How to Identify Common Pet Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced pet care professionals :

The most common clinical signs associated with an insect bite reaction include: swelling and redness at the site of the bite. hives or multiple red, raised swellings over the body. a swollen face or muzzle.
The bite can look like a red, raised skin lesion and occasionally have a white center filled with pus, like a pimple. Applying an ice pack to the area can help reduce pain and swelling. If your dog was bitten by several fire ants, call your local veterinarian to ask if Benadryl should be given and at what dose.
Just like people, dogs can suffer from allergic reactions. The most common causes of these reactions are insect bites. Fleas rate their own discussion, but bee, wasp, mosquito, and spider bites can all cause your dog some discomfort.
Allergies: Allergies can cause your dog`s eyes to swell if they`re exposed to an irritating allergen. Dogs can be allergic to various things, such as pollen, mold, dust, smoke, or insect stings, and these all can cause swelling in the eyes.
VISIBLE PUS & HEAT RADIATING FROM THE WOUND

A dog bite that visibly oozes pus or feels hot to the touch is one of the more obvious signs that the wound is infected. In a case like this, the doctor may need to clean and debride the wound, or prescribe a round of antibiotics.

Prognosis is good for localized reactions, as most clinical signs resolve within 12-24 hours with appropriate therapy. Prognosis is fair to good for patients with more severe reactions, providing prompt medical care is provided.
Can I Give My Dog Benadryl for a Swollen Face? Yes, Benadryl is safe for dogs. You can use it to treat mild facial swelling from food allergies or itchiness due to skin allergies. It can also reduce other allergy-related symptoms, including redness, hives, and inflammation.
Symptoms of an allergic reaction in dogs

hives (patches of red, swollen, itchy welts or bumps) also known as urticaria. facial angioedema (muzzle or eye swelling) itching. gastrointestinal signs (vomiting and/or diarrhea)

Reasons Why Dogs` Eyes Become Swollen

It can occur secondary to an irritant like soap or smoke or an invading foreign matter like dust, hair, and grass. Viruses like distemper, herpes, hepatitis, and canine influenza also could cause eye infections. Funguses and parasites have also been known to result in swollen eyes.

Topical antihistamines — Eye drop antihistamines, such as Zaditor, may be recommended to help with eye itching and redness. Dermatology consultation — Dogs with severe allergies and conjunctivitis may require oral steroids, immunosuppressants, or immunotherapy to desensitize them to their allergens.
If the sting is on the nose, mouth, or around the head, observe your dog for several hours to make sure that any swelling does not interfere with breathing or swallowing. If the swelling increases dramatically after a few minutes after the sting, see a veterinarian immediately.
Make a thick paste of baking soda and water and apply it to the sting site. If your dog has multiple stings or bites, a soothing oatmeal bath is the way to go. Minimize swelling. Apply an ice pack to the affected area for 10 minutes to reduce swelling.
Many times, pet parents don`t recognize the warning signs before a bite, so they perceive their dogs as suddenly flying off the handle. However, that`s rarely the case. It can be just milliseconds between a warning and a bite, but dogs rarely bite without giving some type of warning beforehand.
If you have been bitten by a dog recently, then there are some dietary restrictions that you must follow. In India, various studies have been done and the results have found out that spicy food, potatoes, tomatoes, coriander, dhal, and meat should be avoided completely during Dog Bites.
In the case of a mild reaction, the common symptoms of a bee sting in dogs range from: Bee stinger present (Common locations are the face, lips, nose and paws) Discomfort/Pain – whining, crying, distressed behaviour, licking, chewing, pawing, or scratching at the bite site.
Some dogs can be more sensitive to wasp or bee stings and might have an allergic reaction. This can happen quickly (i.e. within 10 minutes) or may be delayed by a few hours. In very rare cases this can be delayed by a day or so.
Yes, swelling is normal after a dog bite, but increased swelling after the initial first aid can be a sign of infection. Dog bites may be dirty wounds that are prone to infection.
The 10-day confinement and observation period for dogs and cats that bite humans has stood the test of time as a way to prevent human rabies. This quarantine period avoids the need to destroy the biting dog or cat in order to test its brain for the rabies virus.
Treatment with prophylactic antibiotics for three to seven days is appropriate for dog bite wounds, unless the risk of infection is low or the wound is superficial.
While mild reactions tend to clear up with minimal intervention, severe reactions are a veterinary emergency and demand immediate attention. Allergies trigger an inflammatory response that may cause hives and swelling on a dog`s face. The swelling might be especially obvious on the eyelids and muzzle.
Treatment of Facial Swelling in Dogs

Mild swelling may resolve on its own, but you still need a vet to check your pet out and determine why their face swelled up. If the cause is due to dental disease, treatments can range from cleaning to tooth removal.

Nonsteroidal anti-inflammatory drugs (NSAIDs for dogs): Relieve pain associated with surgeries and arthritis including swelling, stiffness, and joint pain. Both Metacam and Previcox fall under this class of medication.
Although relatively safe in humans, ibuprofen and other NSAIDs can be extremely harmful to dogs. Poisoning may happen when pets get into the owner`s medications. In some cases, owners may administer ibuprofen to treat their pet`s pain prior to consulting a veterinarian.
No matter what the cause, an allergic reaction can occur immediately or up to 48 hours later. These reactions can range from mild to severe and life-threatening, so if your dog shows these signs, contact your veterinarian as soon as possible.

the most relevant questions and answers related to your specific issue

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 is house trained but has started pooping in the house, why is she doing that?
ANSWER : A. It could be the type of food you are feeding. If you are feeding a lower quality kibble, it will be packed with fillers. These fillers will cause your dog to poop more than is necessary, and it can cause your dog to poop indoors because of the excess poop. Finding a higher quality kibble like Taste of the Wild, Orijen, or a high quality food like Ziwipeak, or Honest Kitchen, will help with that issue.

Remember to NEVER scold for accident indoors. The more you scold, the more fearful your dog is of pooping in front of you, the less your dog will want to poop in front of you outdoors, the more he will poop indoors, the more you scold… it’s a vicious cycle.

Have you been cleaning messes with Nature Miracle? Pick up a bottle, and try cleaning with that instead of regular cleaner. It will eliminate the smells deep down (even to your dog), which will discourage him from potting in that spot again.

Maybe he needs to be taken outside more often, and maybe he needs to be kept outside longer each time. He should be allowed at least 10 minutes of roaming outside before he has to come back inside. Allow him 10 minutes every single time you bring him outside, just in case he has to poop. He needs every opportunity you can give him. Bring him outside every hour if he’s full grown, every 40 minutes if he’s an adolescent (6-10 months), and every 30 minutes if he’s a puppy (2-6 months). If you have a doggy door, you should still be bringing your dog outside yourself to encourage him to stay outside longer, and poop. When he does poop outside, you should praise him, and reward him with lots of treats!

Q. Whenever I take my dog on walks he always barks at people and others dogs in my neighborhood. What should I do to resolve the problem
ANSWER : A. The very first thing to do is to make sure your dog is getting sufficient physical and mental exercise every day. A tired dog is a good, happy dog and one who is less likely to bark from boredom or frustration. Depending on his breed, age, and health, your dog may require several long walks as well as a good game of chasing the ball and playing with some interactive toys.

Figure out what he gets out of barking and remove it. Don’t give your dog the opportunity to continue the barking behavior.

Ignore your dog’s barking for as long as it takes him to stop. That means don’t give him attention at all while he’s barking. Your attention only rewards him for being noisy. Don’t talk to, don’t touch, or even look at him. When he finally quiets, even to take a breath, reward him with a treat. To be successful with this method, you must wait as long as it takes for him to stop barking. Yelling at him is the equivalent of barking with him.

Get your dog accustomed to whatever causes him to bark. Start with whatever makes him bark at a distance. It must be far enough away that he doesn’t bark when he sees it. Feed him lots of good treats. Move the stimulus a little closer (perhaps as little as a few inches or a few feet to start) and feed treats. If the stimulus moves out of sight, stop giving your dog treats. You want your dog to learn that the appearance of the stimulus leads to good things.

Teach your dog the ‘quiet’ command. Oddly, the first step is to teach your dog to bark on command. Give your dog the command to “speak,” wait for him to bark two or three times, and then stick a tasty treat in front of his nose. When he stops barking to sniff the treat, praise him and give him the treat. Repeat until he starts barking as soon as you say “speak.” Once your dog can reliably bark on command, teach him the “quiet” command. In a calm environment with no distractions, tell him to “speak.” When he starts barking, say “quiet” and stick a treat in front of his nose. Praise him for being quiet and give him the treat.

As in all training, always end training on a good note, even if it is just for obeying something very simple, like the ‘sit’ command. If you dog regresses in training, go back to the last thing he did successfully and reinforce that before moving on again. Keep sessions short, 15-20 minutes max, and do this several times a day.

Q. I was told by my vet that my dogs cherry eye was caused by something hitting his eye when he was poking around under a bush. I was told surgery needed
ANSWER : A. Prolapsed gland of the eyelid refers to a pink mass protruding from the animal’s eyelid; it is also called a “cherry eye.” Normally, the gland is anchored by an attachment made up of fibrous material. The most common sign of “cherry eye” is an oval mass protruding from the dogs’s third eyelid. It can occur in one or both eyes, and may be accompanied by swelling and irritation. He may have acquired it by getting an injury to his eye but this isn’t the case sometimes. Sometimes there is a weakness in the fibrous attachment.

The veterinarian will review the mass in the dog’s third eyelid and determine if there is an underlying cause for the condition. The diagnosis of the prolapsed gland could be scrolled or everted cartilage in the third eyelid, abnormal cells in the third eye, or a prolapse of fat in the dog’s eye.

Treatment often includes surgical replacement of the gland in the dog’s eye, or removal of the entire gland if the condition is severe. Conversely, if medications are recommended, they are typically topical anti-inflammatory drugs that are effective in reducing swelling.

Q. Rescued a dog almost two weeks ago, and now that her kennel cough is gone her personality shines!! No previous training, how should I start?
ANSWER : A. POST FOUR:

After your dog is familiar with the behavior you lured from scratch, and taught to your dog, you can start to use the “no-reward marker” I talked about. What you do is ask the dog to perform the behavior, and if the dog does not perform the behavior, you simply say your no-reward marker (choose one: eh-eh, hey, uh-oh, oops) show them the treat, put it behind your back, and BRIEFLY ignore your dog. Just turn your back for a second or two, before turning back to your dog and saying, “let’s try that again.” When you’re ready to start over with your dog, make sure you move around. If you are repeating the same cue while in the same position, while your dog is in the same position, you are likely to receive the same results. The more you move around, and start fresh, the better your chances are of having your dog listen to your cue the second time around. BIG rewards when they dog it successfully! Lots of praise and treats.

My no-reward marker is “hey.” When my dog does something wrong I say, “hey” and she immediately understands that she needs to offer a different behavior. This is clear to her. I don’t have to say it in a mean way, I simply say, “hey” in a normal tone of voice and she understands what the word means.

Once you’ve built up that connection and communication with your new dog, you can work on all kinds of fun behaviors! I personally enjoy the more zen-like behaviors: https://www.youtube.com/watch?v=ruy9UMcuGh8

I like to teach my dog fun tricks that offer her a “job” to do of sorts like object retrieval: https://www.youtube.com/watch?v=I4iertZSva8

(object retrieval training completed; what it looks like: https://www.youtube.com/watch?v=jx0Dml28FGY)

Scent-games are fun too! Very confidence building. Hide a REALLY smelly treat in a box, and place that box in a line of boxes. Let your dog go in the room while saying something like “search!” or “find it!” and watch them hunt for that smelly treat! Lots of rewards when they find it!

Q. My 4 year old Chihuahua mix began having a series shaking/panting episodes (last 15m- 1hr) out of the blue. Vet’s tests say its not physical.
ANSWER : A. There are many causes for shaking/panting. The shaking and panting are both signs of stress, and your dog may be dealing with anxiety, or stress, related to an event that happened, or is happening. I realize you cannot answer questions on this, however, I will ask some questions that you can ask yourself. Have you recently moved? Have you ever hit or yelled at your dog? Has the weather been bad lately (storms)? Have you had any new guests stay over recently? Have you had any dogs come to your home recently? Have you had any dogs or cats in your yard recently? Was your dog frightened by something initially (a falling pot/pan; a loud bang from the washing machine; a gunshot; a backfiring car/truck; someone screaming in your home/a fight)?

If you answered yes to any of those questions, it could definitely be that. Dogs don’t typically hang on to something for very long, but if it really frightened your pup, then she/he could be feeling serious anxiety related to that specific event, and relating other events to that one.

Do not yell, or hit your dog. I’m not assuming you do, but if you do, please stop doing that right away. It could be that your dog is afraid of you specifically, and you notice the shaking/panting when you are near, because that is the only time your dog is doing it.

If you’d like to purchase a consultation with me (I know, it’s a lot to ask, but I really feel like I could help) I’d be more than happy to ask you many questions, and together we can figure out what the heck is going on here. It’s important that your dog is comfortable, and if your pup is always feeling anxious/uneasy, then his/her quality of life is in jeopardy.

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).

Q. Husband shamed dog for having an accident inside, and now she won’t poop when he takes her out. Can we fix this? He realizes he erred
ANSWER : A. Good on your husband for realizing that scolding is not the way to potty train! Hopefully these tips can help both him and your pup get back on the right track and make pottying outside successful.

If your dog is still a puppy, that is good news as you may be able to more easily time your potty outings with your dog’s schedule. Even if your dog is older, this schedule may help. Dogs generally have to go potty about 15 minutes after eating, drinking, waking up or playing. Knowing this, get your husband to start taking out your puppy at these key times, so puppy gets used to going out with him, and the urge to potty may be higher than any fear to go. If the potty is successful, have your husband reward the dog with a favorite treat! For bowel movements, dogs may take a little more time, and you may have to stand outside for a while (sometimes even 10 minutes) to give your dog a chance to go. If she doesn’t go, take her back inside and play some, then try again in about 15 minutes. Again, a success equals a treat which most dogs will like right away!

For any indoor potty accidents that occurred, an enzymatic cleaner is great for cleaning up urine and stool. Not only does it remove the stain and smell, but it breaks down the enzymes in the urine and stool your dog can smell, which may deter her from going potty there again.
