A. No I wouldn’t recommend giving benadryl. Starve your dog for 12 hours and then gradually reintroduce food. If the vomiting continues then you should see your vet or emergency vet as it could be an enteritis or even a blockage.

How to Identify Common Pet Problems ?

You can try feeding her a bland diet mixture of boiled white chicken and boiled white rice for 2-3 days and see if that helps settle her stomach. If she continues to vomit or becomes lethargic, then she should see your veterinarian right away.
Allergies. If your dog eats something they`re allergic to, vomiting may occur and bile may be present. Often, this happens when a dog switches their diet.
Ginger is one of the best home remedies for your dog`s vomiting and upset stomach. You can make ginger tea by boiling fresh ginger root in water, cooling it, and giving it to your dog in small amounts throughout the day.
Should I feed my dog after vomiting yellow bile? If your dog is vomiting bile after a long period of fasting, this may mean that the lack of food in their stomach has caused bile to leak from the small intestine back into the stomach. In this case, you can feed your dog small amounts of food after they vomit.
Yellow vomit in dogs can sometimes happen due to a food allergy or intolerance. Ingredients that your dog is sensitive to can cause irritation to the lining of the digestive tract which in turn can lead to vomiting. Usually, they will also have other symptoms such as diarrhea and/or itchy skin.
A dog may be throwing up yellow bile because its stomach is empty and gastric acids are irritating the stomach lining. But, it can also be a yellow foreign object or substance your dog may have ingested, so it`s important to not dismiss yellow bile as a sign of hunger.
They can appear on the skin as rashes, red feet and hot spots. They can appear in the ears or in the respiratory tract. Allergies can also manifest as digestive symptoms including vomiting or chronic diarrhea.
Your vet may recommend treatment options involving changing your dog`s food – an easy-to-digest, low-fat, high-fiber diet could help resolve the issue. Feeding your dog smaller meals more frequently could also be helpful.
Ursodiol (brand names: Actigall®, Urso®, Ursofalk®) is a bile acid used to treat the symptoms of gallbladder or bile related liver diseases such as gallbladder mucocele, cholestasis, and chronic liver inflammation.
As a dog owner, watching your furry friend vomit can be a worrisome experience. And when the vomit is yellow in color, it can make you even more concerned. Yellow vomit in dogs can be caused by a variety of factors such as bile buildup, food allergies, empty stomach, intestinal blockage, or worse, liver disease.
Putting food into an upset tummy is irritating and makes it more likely that vomiting will continue. Take your dog`s food away for 12–24 hours, and don`t give them any treats or table scraps.
In cases where the cause is thought to be dietary indiscretion, your veterinarian may advise you to withhold food for a short time, until vomiting appears controlled. After this time, you may be advised to feed your dog a bland, easily digested diet.
Benadryl is a relatively safe and effective medication for dogs when used according to the instructions of a veterinarian. As with any new medication, always observe your dog closely after administration to make sure there aren`t any adverse reactions.
Diphenhydramine (brand name: Benadryl®, Vetadryl®, Banophen®, Genahist®, Diphenhist®, Unisom®, Sominex ®) is an antihistamine used in cats, dogs, ferrets and other small mammals, birds, horses, and cattle to treat allergic reactions, motion sickness, and vomiting.
Benadryl dosage for dogs.

According to the Merck Veterinary Manual, the safe dosage is 2-4 milligrams of medication per kilogram of weight, or 0.9 to 1.8 milligrams per pound. This amount can be administered two to three times daily, depending on your dog`s symptoms.

The most common food allergens in dogs are proteins, especially those from dairy, beef, chicken, chicken eggs, soy, or wheat gluten. Each time a pet eats food containing these substances, the antibodies react with the antigens, and symptoms occur. Virtually any food ingredient can produce an allergy, however.
Some symptoms include loss of appetite, weight loss, stomach/abdominal pain, vomiting and fever. Check in with your vet if your pet exhibits any of these symptoms.
Stay hydrated by sucking on ice chips or frozen fruit pops. Try drinking sips of water, weak tea, clear soft drinks without carbonation, noncaffeinated sports drinks, or broth. Sugary drinks may calm the stomach better than other liquids.
Green or yellow vomit, also known as bile, is produced by the liver and stored in the gallbladder. The release of bile occurs when an individual is vomiting on an empty stomach or is suffering from bile reflux.
One of the most common ways to help a dog that is recovering from vomiting is to feed them a bland diet (usually white rice, sweet potato, boiled chicken or white fish). If your dog has been treated by your vet then they may also give your dog a specially prescribed diet and some medication to help them feel less sick.
If your pooch is mildly dehydrated provide your pet with small amounts of water to drink every few minutes or offer your dog pieces of ice to lick. To help restore your dog`s electrolyte balance you could also provide your pup with Ringer`s lactate (an electrolyte replacement fluid).
There are also several at-home remedies you can try that may help your dog. Try feeding your dog a small amount of plain, unsweetened yogurt to their food. This can help to restore the balance of good bacteria in the gut, which can help to ease stomach upset.
You should hold back giving water to a sick dog for two hours and food until 6-8 hours after their last episode of vomiting. Once this period is over reintroduce small, bland meals such as white chicken or rice gradually. If everything is ok the next day your dog can gradually return to their normal diet.

Q. How do I determine how much my overweight pet should weigh?
ANSWER : A. There are many tools to determine overweight and obesity levels in pets. A new tool, morphometric measurements and body fat index, are available to accurately determine a pet’s ideal weight; this will allow an accurate determination of the amount of food a pet should receive to achieve weight loss. Feeding the correct amount will lead to greater weight loss success.

There are many weight loss food options to help pets reach their ideal weight. Your veterinarian can help make a ideal weight recommendation. Here are some tips to help your dog lose weight in a healthy and safe way:

1. Diet: Providing a healthy and well balanced diet is essential to your pet’s overall health. Finding the right food for your dog can be a challenging process. For those overweight animals many commercial dog companies offer weight loss diets, but it is important to evaluate food labels for adequate nutritional content.

You want to ensure you are not missing other essential vitamin or mineral content. Volume of food is also important and the amount of food that works for one breed of dog may not be the same for another breed of dog. Portion control as opposed to free-choice feeding can help your dog to drop a few unnecessary pounds.

There are also prescription weight loss foods designed by veterinary nutritionists, such as Hill’s r/d (http://bit.ly/1AoENSd). Some pet owners find that home cooking is the best option for helping to provide a well-balanced and realistic diet plan. There are websites such as balanceit.com that offers recipes to fit your dog’s specific needs. Consulting with your veterinarian or a veterinary nutritionist to find the appropriate diet is a great way to help your dog be as healthy as possible.

2. Exercise: Another great tactic for weight loss for your dog is exercise. Whether this is through running, walking or playing with a favorite toy all of these are wonderful types of exercise to help keep your dog at a lean and healthy weight.

For those pet owners with busy schedules utilizing professional dog walking services or playtime through dog daycare services is another option. It has been shown that those pet owners that exercise regularly with their pets generally live a healthier lifestyle.

3. Physical therapy: As animals age pet owners offer encounter their favorite canine having more difficulty walking and have a dwindling desire to play with toys. Physical therapy, specifically hydrotherapy is a wonderful way to help older and arthritic animals gain more mobility and lose weight. Hydrotherapy has been proven to have several therapeutic effects on the body including, muscle strengthening, relief of swelling, decreased joint pain, less stiffness in limbs, improved circulation, weight loss, and increased tissue healing to name a few. For more information on the benefits of hydrotherapy:

4. Veterinary visit and blood work: Weight gain can also be related to underlying health concerns such as hypothyroidism or other endocrine disorders. Scheduling a veterinary evaluation and routine blood work can be another important component in increasing the longevity of your dog’s life. Conditions such as hypothyroidism that predispose dogs to gain weight can be treated with a daily medication to improve hormonal balance. If feel that your dog is unnecessarily overweight there can be an underlying health condition that needs to be addressed.

5. Healthy treats: Pet owners love the chance to reward their favorite canine companion with treats and most dogs jump at the chance to consume these delicious products. The problem is many treats, which can include commercial dog treats or table scrapes can add many unnecessary calories to your dog’s daily intake. Reading labels and making note of the calories in these treats is an important component of understanding your dog’s overall health. Treats should not exceed more than 10 percent of your pet’s daily calories. There are healthier treats that can be offered to your pet to keep calories lower yet provide a fuller sensation. A pet owner can add steamed or pureed vegetables, such as carrots, green beans or sweet potato to add more fiber and thus a fuller feeling for your dog.

Q. My dog licks his feet and legs and they are turning brown. He is a white dog. Can you help?
ANSWER : A. Licking the feet and legs can be caused by a number of things in dogs including allergies, illness or even stress behaviors. Allergies are the most common in dogs, with yeast infections coming in second. Allergies can cause the area to become red and itching, making your dog want to lick and chew on them. Over time, the area may become stained from saliva, especially in lighter or white-coated dogs. Yeast infections are also common between the toes, and may cause a smelly “corn chip” smell to appear near your dog’s feet. Again, dogs will attempt to lick and chew to relieve the itch. Keeping the feet clean and dry can help relieve both allergies and infections and pet wipes or a baby wipe of all paws when your dog comes in from outdoors may also help. Keeping your dog from licking the space with either dog booties or an Elizabethan collar is also good as it will prevent secondary infection and staining of the paws and legs. If your dog is determined to keep licking and keeping the feet clean and dry do not help, then your vet can help by providing a medication to treat any infection or provide relief of allergies.

Q. Which common foods are poisonous to pets?
ANSWER : A. That’s a great question. As responsible pet owners we need to be aware of food items that can be harmful to our canine or feline companions. Here are some of the most common foods proven to cause illness in our animals at home:

Chocolate: A favorite and irresistible treat amongst most humans, chocolate is considered toxic to dogs. In very small amounts it is usually not a huge issue, but with larger volumes and with darker chocolates pet owners should be concerned. Chocolate contains methylxanthine theobromine, which is similar to caffeine. Chocolate ingestion can cause vomiting, diarrhea, hyperactivity, issues with normal heartbeats, seizures, and in some severe cases, death. It is best to keep your favorite chocolate treats in a good hiding spot and out of reach of your dog or cat.

Grapes and raisins: Dogs should not consume grapes and raisins because of the risk of acute kidney failure. Most dogs experiencing grape or raisin toxicity will begin to have vomiting and/or diarrhea within 6-12 hours of ingestion. Other abnormal clinical signs include lethargy, abdominal pain, dehydration, and tremors. Kidney failure develops within 24-72 hours of the initial ingestion. There are some dogs that do not experience these devastating side effects. It is best to contact your veterinarian or veterinary emergency facility if you believe your pet has ingested grapes or raisins.

Garlic and onions: We often forget that our meals contain these two popular ingredients and will allow our furry companions a few bites or licks. Onion and garlic both can cause a type of poisoning that results in damage to red blood cells, making them more likely to rupture. They can also cause stomach upset and mouth irritation. Look for pale gums, increased breathing or drooling or any vomiting or diarrhea.

Bread dough: Unbaked bread dough is considered poisonous to our pets. The bread dough, when ingested, expands in the stomach because of the warm and moist environment. This can lead to a bloated or even twisted stomach. In addition yeast is often added to our baking products to help get bread to rise, and when this yeast is fermented it produces both carbon dioxide and alcohol. The alcohol produced can be absorbed into the bloodstream and causes dangerous drops in blood sugar, blood pressure and body temperature. Common clinical signs include vomiting or retching, distension of the stomach, weakness and collapse.

Macadamia nuts: Ingestion of these nuts are not proven to be fatal in dogs but can cause them to experience uncomfortable clinical sings, including fever, joint stiffness, vomiting, tremors and difficulty walking, especially in their hind legs. Often your pet will start to feel better after about 48 hours, but supportive veterinary care (such as pain medication) may help ease their discomfort.

Xylitol: The most common ingredient used in sugar-free gum is xylitol, which is a non-caloric sweetener. It is also found in some oral rinses, toothpastes and vitamins. Xylitol and dogs do not mix – it can cause a dangerous drop in blood sugars levels. Dogs will often display signs of disorientation, black tarry stool, tremors and seizures. If severe enough some dogs have developed liver failure. Keep your gum away from your canine companion.

Avocados: Avocados are not actually poisonous to dogs or cats but as many veterinarians can tell you the avocado pits can cause a foreign body obstruction. Avocados contain persin, which is actually toxic to the majority of pet birds. The abnormal clinical signs associated with avocado ingestion in birds include, respiratory distress, inability to perch, liver and kidney failure and sudden death.

Go forth and enjoy your favorite foods, but keep in mind which foods you should avoid sharing with your furry family members. Whenever in doubt, contact your veterinarian for healthy and safe food suggestions.

Q. My dog itchs all the time a codozon shot helps but don’t cure it after a bath she turns red and still itchs I changed dog food that didn’t help no fle
ANSWER : A. Do you live in a region where fleas are prevalent. Where I live the fleas are truly horrible, and I see many animals developing a flea allergy. This usually presents as relentless itching especially at the base of the tail, although it can be all over the body. Often on exam I won’t find a single flea, just red bumps, hair loss and itching. In response, I will start animals on an oral steroid such as prednisone (I think your doctor has administered an injectable steroid), while at the same time bathing the animal and starting on an oral flea preventative such as Comforts which I then re dose at 3 weeks instead of 4. Additionally, the environment needs to be decontaminated- flea bombing the house, vacuuming often and washing bedding on hot. The flea life cycle is short, however, so this needs to be one frequently as they will just continue to hatch in your home. Most importantly, I tell my clients, that any steroid (oral or injectable) does not fix the problem, but rather suppress your dogs reaction to it thereby making them more comfortable. Just the steroid alone changes nothing except giving them a brief break from their symptoms.

Now that I have spoken in depth about flea allergy, there is a potential that it is something else. Food allergies are slow to develop, and slow to change. If you wanted to eliminate a potential food allergy I would switch to a novel protein, limited ingredient diet. For example, lamb as the protein source if your previous food was always chicken or beef, and in a formula with very limited ingredients such as lamb, rice and veggies. A pet store should be able to help you with this. While on this diet they cannot have any additional treats for 1 month, to see if you have eliminated the allergy. From an Eastern Medical perspective, I also recommend novel proteins that are “cool”, such as fish, lamb, or duck while avoiding “warm” foods such as beef, chicken, pork.

Finally, all animals with allergies should be on an Omega 3 supplement. Given regularly, this can help reduce overall inflammation in the body both in the skin, joints, and other tissues. Good for allergies, arthritis and overall health. My dogs are on fish oils, but one of my dogs who is allergic to fish gets flax oil instead. I would be happy to consult with you further, but I hope this helps to some degree.

Q. My dog has no fleas, but is scratching and licking continually. He has been through a round of prednisone and it hasn’t helped. What can I do?
ANSWER : A. Itching can be caused by more than just external parasites, and if your dog is already on a flea medication, then it is possibly not the case. Itching can indicate anything from allergies to even minor skin infections causing problems. If your dog has been treated with prednisone (a steroid that inhibits the immune system) and it did not help, then looking at other options may help.

Food allergies are very common in dogs and can present with itching and licking all over the body rather than on just one spot. Common food allergens include ingredients such as wheat, corn and soy products, however dogs can be allergic to almost anything! Starting a food trial of an allergen-friendly diet from your vet or pet store that avoids these common ingredients may help. The food should be switched over a period of 7-9 days and then given about a month to decide if it is helping.

Small skin infections or yeast in the skin can also cause itching, however this itching is often more specific to a certain area of the body (such as the toes, or base of the tail). Your vet can perform a skin scraping of the area to be cultured at a lab to look for any yeast or bacteria. If they are present, a medication given either orally or placed on the affected area can clear up the infection.

In some cases, licking and chewing can actually be due to a boredom or anxiety behavior. Dogs may lick one spot obsessively to the point of creating sores or wounds in the area. Stopping your dog from licking and chewing either through the use of dog booties, no lick strips, T-shirts or even Elizabethan collars can break the habit and give the area time to heal. Licking and chewing can also cause the spread of bacterial infections so should be deterred even if not behaviorally caused.

Q. My 4 yr old male Catahoula Leopard Dog mix is a rescue. He’s become very possessive of me around larger dogs. How can I correct this behavior?
ANSWER : A. Sudden behavior changes can sometimes indicate an underlying health issue, so scheduling a checkup with your regular vet is always the first step. Once any health issues have been addressed, then you can address the behavioral ones. It is very common for dogs to become “possessive” of people or objects when around other dogs or people, and is called location guarding. Possession of objects or places can be a little easier to manage, however possession around other dogs can be treated as well. Working from a distance in a technique called BAT or Behavioral Adjustment Training may help. This technique involves your dog and another calm dog. Start off at a far distance and then move in until your dog becomes reactive or wary of the other dog. Move back a small amount and wait for your dog to become calm. If he shows calm behavior, reward with lots of praise, treats and love! If he becomes agitated or possessive, move back until he is calm, or stop the session completely and try again later. While this may take some time, it can help dogs learn that other dogs are not a threat to them or their people. Reading more information about BAT training or contacting a local trainer in your area can help with further advice and techniques!

Q. Want a pet cat companion for my dog Lucky, who is 5. The problem is that I’m somewhat alergic to cats. So, not sure what to do!
ANSWER : A. Dogs can make friends with lots of species, including cats! If you are heart-set on a cat, allergenic breeds are available such as hairless or lesser haired Sphinx and Devon-Rexes. However these breeds can be rare and hard to find at times. A short-haired cat that is brushed regularly may also cause less allergies. Many people with allergies are also able to take medications such as a daily allergy medication or spray like Nasocrom which can make living with a cat much easier.

If your dog is very friendly with other dogs, then getting him a dog friend may be an option! That would keep you from needing to get a cat and having an allergic reaction. Looking at your local animal shelter may help you to find a dog for adoption that is similar in personality and play style to your current dog. Many shelters will also let you introduce your dog to the one you are interested in adopting to see if they will be a good fit! If you can’t get another pet at this time, taking your dog to a local dog park or dog meetup can help him to get more social interaction and get out extra energy without the need for caring for another pet.

Q. Why does my dog eat grass?
ANSWER : A. As another user mentioned, dogs can eat grass when they want to vomit. Sometimes, when a dog has an upset tummy, they will eat grass. If you notice your dog eating grass frantically, you can assume vomiting will shortly follow. Grass does not digest and pass normally. If your dog eats too much grass, it can cause serious issues with pooping. Your dogs poop can end up all tangled inside of her, and it can need veterinary assistance to remove it. The same goes for celery, so avoid feeding celery to your dog.

The other day my boyfriend accidentally left the laundry room door open where we were keeping the trash that was filled with cooked chicken bones. She ate one of the chicken bones lightning fast. We had to induce vomiting by feeding her some hydrogen peroxide. After we had fed her the peroxide, she immediately began frantically eating grass because her tummy was upset.

If there is something lacking in your dogs diet, it could be that your dog is eating grass to make up for it. I am sure that my dogs diet is extremely well balanced (I do not only feed her an air-dried raw food-type diet (Ziwipeak), but a wide variety of safe, healthy foods), so when she eats grass, I know that it is because she has an upset tummy.

That is why I think it is important making sure your dog has a very well balanced diet. If your dog is on a low quality kibble, your dog may be trying to let you know by eating grass (or eating poop).
