Experienced and professional animal trainer provide their insights in answering this question :
A. Vomiting and diarrhea can occur if food is switched too quickly. Dogs generally need a slow changeover of foods over a period of a week or so to allow their guts and the gut bacteria to adjust. If there has only been one vomiting and diarrhea episode, removing the food for a few hours then feeding a bland diet of boiled chicken and plain rice can help soothe the stomach. You should then return to his old food and begin a gradual changeover of foods starting with 3 days of 75 old/25 new, 3 days of 50/50 and then 3 days of 25old/75 new. However if the vomiting and diarrhea symptoms do not improve, it may indicate something else causing his digestive distress and an appointment should be made with your local vet.

Treatment of Diarrhea Due to Diet in Dogs

Anti-diarrhea medication may also be prescribed. Food may need to be withheld for at least 24 hours. Small amounts of water will need to be given frequently to keep them hydrated if they are not already dehydrated. A bland diet can be given after 24 hours.

Most pet`s suffering from diarrhoea due to a change in food will recover within 1-3 days.
Withholding food for 12 to 24 hours, and providing water in small amounts frequently, can clear the cause of the upset and allow the gastrointestinal tract to settle. It`s usually the first line of attack for diarrhea. Before you decide on a fast, be sure that your dog is healthy enough to endure it.
Sudden Change in Diet

Introducing a new diet to your dog can lead to gastrointestinal intolerance and result in vomiting. This is often because he does not digest the food and in some cases, may have an intolerance to it. His body will then work to eliminate the food from his system.

Switching your dog`s food abruptly can cause gastrointestinal upset such as vomiting, diarrhea, and a decreased appetite. Any time you decide to change your dog`s food, you should transition to the new diet gradually in order to give your dog`s system time to adjust to the change.
As a home remedy for diarrhea, try giving your pup a small amount of pureed pumpkin (one to three tablespoons, depending on your dog`s size). Make sure that it`s 100% pumpkin with no sugar or other additives, which may upset your dog`s stomach even further.
Pets that have chronic soft stool or chronic full-blown diarrhea should definitely be examined by a veterinarian, even if they are otherwise behaving normally. In these cases, there is likely an underlying problem that`s causing the diarrhea. This is especially true with older pets.
Usually most diarrhea will run its course within two to four days, although in some cases, it can last longer. If there are any other signs of illness like vomiting, loss of appetite, depression, or pain, a veterinary trip is in order.
When should I take my dog to the vet for vomiting and diarrhea? If their symptoms haven`t improved within 12-24 hours you should bring them to the vet. You should bring them sooner if they`re displaying other symptoms such as; severe tummy pain, not drinking, lethargy or if there is blood in the vomit or feces.
My dog has diarrhea, What should I do? Fast your dog for 24 hours. Only water is permitted. After the 24 hour fast, begin feeding a combination of boiled white meat chicken (with all the skin and fat removed and the water poured off) and boiled long grain white rice.
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.
Their digestive enzymes and microbiome have adapted to the diet they`re used to eating. An abrupt change in the type of diet (change in brand or protein base) will cause an inflammatory response along the intestinal lining, leading to gastrointestinal signs such as vomiting and diarrhea.
A sudden change in diet can upset your dog`s stomach and intestinal tract, leading to diarrhea. The usual rule of thumb is a gradual change if you are switching your dog`s food. The general recommendation is to slowly increase your dog`s new food while decreasing the current food over the course of one week.
Vomiting and diarrhoea can have a wide range of causes including parasites, a viral infection, a bacterial infection, toxin ingestion, a gut obstruction, a new food allergy or sensitivity, pancreatitis etc.
A bland diet for 24 to 48 hours may help to resolve your pup`s issue. Plain-cooked white rice with a little chicken and some canned plain pumpkin (not pumpkin pie filling) may help to make your pup`s tummy feel better. Once your pooch feels better, gradually reintroduce their regular food.
Ensure your dog is hydrated and getting ample water

Diarrhea can easily dehydrate your dog, especially if she`s young, so it`s important to ensure that even if you`re limiting her food intake that she has ample access to fresh, clean water.

Rest. Just like with us, rest is important. Give your dog a quiet and comfortable place for them to recover. It is likely best to be a place close to a door to go outside, and that has an easy-to-clean floor for those unfortunate poop accidents.
Recovery time usually is within a few days but sometimes can last a week or more. If left untreated, gastroenteritis can worsen and cause severe dehydration which can be life-threatening.
If loose stool lasts more than two days, call the vet

Diarrhea is no fun for you or your dog, but the good news is that most cases resolve on their own. Mild cases are usually uncomplicated, and the dog is otherwise happy and normal. “Many cases of diarrhea in dogs and cats are mild and self-limiting,” says Dr.

Loperamide (Imodium®). This medication is a good treatment for diarrhea in a pinch and should be safe for your dog if dosed at 1 mg per 20 pounds of body weight. Only give one dose. If the diarrhea does not resolve, contact your veterinarian.
Anti-diarrheal agents, de-wormers, and/or probiotics may be prescribed.” Anti-diarrheal agents, de-wormers, and/or probiotics (bacteria that support intestinal health) may be prescribed. There are several probiotic products that may be helpful in dogs with diarrhea.
Fluids given at the veterinary clinic (this helps restore hydration and electrolytes, which are commonly lost via the vomit and diarrhea). Medications for nausea and to help firm up the stool. Treatments for underlying causes (for example, antibiotics or de-wormers).
Ingesting toxins or poisons. Medications such as antibiotics. Parasites – roundworms, hookworms, whipworms, Coccidia, or Giardia. Viral infections such as parvovirus, distemper, or coronavirus.
Skip a meal. Yes, do NOT feed your dog for at least 12 hours. Water is to be given, just do not allow your dog to drink large amounts at a time.

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.

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.

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.

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 cocker spaniel is 9 years old. He has involuntary bowel movements (little drops) very frequently, especially when he is asleep.
ANSWER : A. Is your dog on a senior dog food? I would get your dog on a high quality high protien dog food. Ask a pet store assosicate or your regular vet for a food recommendation. When you buy a better food the dog will have to eat less to get the same amount of energy from the food. The dog has to eat more of the cheaper foods to get the energy it needs from it. Meaning more poop and buying more food. So the cost really evens out. So the lessen your dogs bowel movements get on a better senior dog food. Next talk to your vet they may have a recommendation. If you switch dogs do it slowly by mixing the foods. Start with 10% new 90% old mixed for at least a week until you have switched to 100% new 0% old. Senior foods have more fiber to help with bowel movements. Take the dog outside to go potty more frequently, right before bed time.

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. What is the best limited ingredient dog food for a dog with allergies? Can I buy it online or do I need to get it from a vet? Thanks
ANSWER : A. I’m going to recommend a dog food that is extremely expensive, but absolutely worth the price. It is a food that is fantastic for dogs with many allergies because it is essentially just air-dried raw meat, muscles, vitamins, and kelp. It is called Ziwipeak http://ziwipeak.com/ and it is the best dog food on the market! I feed it to my dog so I do not have to worry about getting raw-food portions right. If you’re worried about the price, there are so many other types of food out there you’ve probably never heard of. You do not have to get food through the vet in order to find the right food for your dog. Many grain-free foods are typically good for dogs with allergies, brands like Merrick, Taste of the Wild, Orijen, etc are great kibbles. It may be pricey, but it’s all about trial and error here unless your vet can tell you exactly what the allergy is and how to manage it.

Q. My 20 month Cavalier doesn’t eat unless I let him eat from my finger, then he eats. Sometimes he will only eat once a day and leave his food.
ANSWER : A. It is possible that your dog is just not satisfied with his current food, or may be a picky eater. There are several things you can try to encourage your dog to eat.

The first step is to remove any additional treats or people food that may be more enticing to your dog than his own meal. If you feel you must give him some form of treat, be sure to place them directly in his food bowl and mixed with his regular diet. This allows him to get some snacks while also “forcing” him to try out his current meal to get the reward.

Enticing your dog to try his food by adding a pet-safe gravy or even a few treats of plain boiled chicken mixed in can help. Be sure to mix the foods thoroughly so he must explore his own food before getting the treat.

Some small breed dogs may also have a hard time with certain bowls and their collars. If there is a metal name tag on the collar and a metal bowl, the clinking sound can sometimes scare off dogs and make them not want to eat from their bowl. Using a bowl of a different material, or removing the collar prior to a meal may help with this issue.

Your dog may also just not be into his current food and may like another variety better. You can try a new variety by gradually switching over a period of 7-9 days, slowly adding in more new food and removing old until it is switched. This change may encourage him to try out meals again, and the slow changeover will allow his body to adjust to the new diet without digestive upset.

Q. We have a 3 yr old Weiner dog, she is having pus in her eyes, I took her to the vet he gave me derma vet ointment, used it as the doctor prescribed
ANSWER : A. If the pus really isn’t all that bad, and it’s just some discharge, your pup may benefit from a diet change. It could be that the food you’re feeding just isn’t right for your dog, and that’s okay! Dogs grow and change over time, and now that your dog is fully matured, a diet change may be in order. Try something like Taste of the Wild, maybe a grain free dog food, Orijen, or Ziwipeak. These are all really great food options.

If the pus is really bad, and continues to get worse, see your vet again and let them know what’s going on. Maybe you could try a diet change, and then see if there are any improvements.

Remember, you should always gradually change a dogs diet. By gradually, I mean you put a tiny bit of new kibble in with a bowl of the old kibble. Reduce the old kibble by just a few bits of kibble. Throughout the course of at least two weeks (or as long as you want depending on whether or not you want to finish off the old food) you slowly add more of the new kibble while removing some of the old kibble. This makes the process gradual, and won’t cause any tummy-upset in your dog.

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. My dog has suffered from diarrhea with vomit and bloody stools for about 3 months. Vet has given Metronidazole, but hasn’t been effective
ANSWER : A. Several things can cause a dog’s diarrhea, and chronic diarrhea can sometimes be hard to treat. However the most common causes of chronic diarrhea can be from food allergies to certain ingredients in the diet as well as a disruption in the gut bacteria. Metronidazole helps with chronic diarrhea in some cases if there is an underlying bacterial condition. Checking your dog’s food for common allergens such as wheat, corn or soy products may alert you to a problem as these can cause a lot of digestive issues in some dogs. Some dogs may also be allergic to more common protein types such as beef, lamb or even chicken, so finding a food with an alternate protein source can also help. Natural remedies to help clear up diarrhea can also include adding plain yogurt to meals to seed the gut with healthy bacteria, or adding pureed pumpkin to provide a fiber boost to firm up stools. However, if these things don’t help with the diarrhea, additional testing and treatment with your vet is best.
