When used in moderation, Pepto-Bismol isn`t toxic for dogs. In fact, it`s been found to be an effective treatment for diarrhea in dogs when given in small doses. But when Pepto-Bismol is used in excess, it can actually cause vomiting and diarrhea in dogs.
If your dog has diarrhea, constipation, or nausea without any additional symptoms, it is generally safe to give your dog Pepto-Bismol. It is important to note that you should only give your dog Pepto-Bismol for a day or two.
Pepto-Bismol can be used in dogs, but it does not suit every dog, and chronic use is not recommended. If your dog has gastrointestinal signs and you`re considering using Pepto-Bismol, you should consult with your veterinarian first and administer the medication to your dog only under their direction.
Some tried-and-true methods include: Rice water: Boil high-quality rice in a lot of water, remove the grains, and offer the dog the creamy white soup that`s left. A splash of broth or a bit baby food will make it more palatable. Plain white rice.
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.
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.
Pepto Bismol is not recommended for dogs due to its active ingredient Bismuth Subsalicylate, which can be toxic to dogs when ingested in large quantities. Ingestion of even small amounts can cause side effects such as vomiting, diarrhea, black or tarry stool, and abdominal pain.
If your dog has diarrhea but is acting fine and isn`t displaying any other symptoms, the issue is contained in the GI. This means it`s more than likely that your dog ate something that isn`t agreeing with them or has a parasite infection.
Kaopectate for dogs is an over-the-counter drug that veterinarians sometimes recommend for dogs with gastrointestinal upset. Kaolin and pectin were the primary ingredients in Kaopectate`s original formula, though in recent years, these were swapped out for bismuth subsalicylate, the active ingredient in Pepto Bismol.
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.
Bland, starchy, low-fiber foods like those included in the BRAT diet (bananas, bananas, rice, applesauce, toast) are binding, which can bulk stool and help you get rid of diarrhea fast. You can also try probiotics, glutamine supplements, or home remedies like herbal teas and rice water.
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.
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.
Wait until your dog has stopped vomiting for at least 2 hours. Give water very gradually and slowly. Start off by giving one or two tablespoons every 15 minutes. If your dog vomits the water offered, you may try again in a couple of hours, but this time give ice cubes.
Vomiting may also be caused by something more serious, such as toxin ingestion, gastrointestinal obstruction, pancreatitis, and more. Vomiting is one of the most common signs of illness reported by dog owners. Dog vomiting and diarrhea often occur together, and loss of appetite or lethargy can also accompany the puke.
Allow them to rest. Don`t force your dog to play or walk if they don`t seem interested. Their body will need to naturally recover after vomiting, which is generally over a period of 1-2 days.
Dogs need roughage in their diets and grass is a good source of fiber. A lack of roughage affects the dog`s ability to digest food and pass stool, so grass may actually help their bodily functions run more smoothly.
Treatments for Dog Constipation

One of the easiest and most common at-home treatments for constipation in dogs is to feed them some canned pumpkin. Pumpkin is a high-fiber food and is perfectly safe for a dog to ingest, as long as nothing else has been added to it.

Some of the signs of parvovirus include lethargy; loss of appetite; abdominal pain and bloating; fever or low body temperature (hypothermia); vomiting; and severe, often bloody, diarrhea. Persistent vomiting and diarrhea can cause rapid dehydration, and damage to the intestines and immune system can cause septic shock.
There are no safe OTC anti-nausea or anti-vomiting (anti-emetics) medications for dogs. Giving your dog these medications can mask symptoms in dogs that have swallowed a foreign body, have an obstruction, or are experiencing a serious illness.
If your dog is constipated, he or she will probably attempt to pass feces unsuccessfully several times. You may observe your dog circling excessively, scooting (dragging bottom along the ground) or squatting frequently, or even crying out in severe cases.
Start by placing your dog in an upright position and rub behind the back leg. Your dog may begin to kick the rear leg, continue to rub until the tail begins to rise. Then, place your dog on their back and rub their left side vigorously for several minutes. As your rub the vent begins to open so your dog can poop.
Diarrhea in dogs can occur suddenly and last as long as a day or two up to a few weeks or months. If your dog`s diarrhea persists for more than a day, dehydration can be a concern. Diarrhea that lasts longer can be an indication that your dog has an underlying health issue.
Diarrhoea is passing looser, watery or more frequent poo (stools) than is normal for you. It affects most people from time to time and is usually nothing to worry about. It can be distressing and unpleasant. It normally clears up in a few days to a week.

Q. I have a yorkie that is 10.2 pounds. I came home from work to loose stools and vomiting after her meal. Can I give her pepto bismo? Liquid?

Q. Healthy German Shepherd has extremely loose stools once a day. I added 2 spoonfuls of pumpkin puree that hasn’t helped. No diet changes. Any advice?
ANSWER : A. Loose stools can be caused by a number of factors, and the first step is always to bring a stool sample to your local veterinarian to check for anything. Fecal exams can check for common bacteria and parasites in the stool that may cause chronic diarrhea.

Diet problems can also play a factor in loose stool as well as chronic illness. Dogs can be allergic to many different ingredients in the diet, however grains such as corn, wheat and soy products can be the most problematic. Adding a probiotic supplement can sometimes help such as a scoop of plain yogurt ever meal, or commercial product from your vet.

Illnesses and metabolic disorders may also cause chronic loose stools. German Shepherds are prone to a disease called Exocrine Pancreatic Insufficiency which is a problem with the pancreas (the same organ that dysfunctions in diabetes- however that is ENDOCRINE function in that case) producing enough digestive enzymes. This causes stools that may be loose, discolored grey or yellow and appear very fatty in color. Shepherds can also be prone to chronic small intestine infections that cause loose stool as well. Luckily, treatment for these conditions often just involves adding a daily digestive enzyme supplement to the food, or daily anti-biotic designed specifically for chronic bowel issues.

Q. My puppy is throwing up her food this morning and yellow foamy stuff. Please help!
ANSWER : A. If the vomiting has only occurred once, it may be due to the fact that there was something causing a minor upset stomach in your pup. Yellow foam is often acid, and tummies that are upset or that have been empty for too long can cause this to appear in vomit. It may just be that your puppy needs an extra meal in the day to help keep her stomach happy. Eating a meal too quickly can also cause a pup to vomit up undigested food and foam, and feeding smaller meals more often, or slowing down your dog’s eating can help.

If the vomiting has only happened once, pick up your puppy’s food for an hour or two and then offer a bland meal of plain boiled chicken and plain rice. These bland ingredients can help settle upset stomachs while being enticing “people food”. If the vomiting does not occur again, you can return to a normal feeding schedule.

However, if the vomiting continues, worsens, or new symptoms appear along with it, then it is a good idea to schedule an appointment with your vet to rule out any more serious causes.

Q. My new cat seems to constantly have loose stools. I have tried to limit what he eats but with 2 other cats it’s difficult. He also ate a plant I had
ANSWER : A. Many plants can be poisonous to cats, so if you know the type of plant eaten it is best to look up if it is safe for your cat to do so. If you suspect the plant is toxic, it is best to contact your local vet for care.

Loose stools in cats can be caused by a number of things ranging from chronic stress, internal parasites, food allergies, to digestive upset and internal illness. You can try some home remedies such as adding pureed pumpkin or plain yogurt to meals which may help bulk up the stool some and is safe for your other healthy cats to ingest.

However if the loose stools continue, bringing in your cat as well as a sample of his stool to your vet is best. They can check for any internal parasites which may be causing the issue, as well as look for any underlying conditions causing it. If a food allergy is the cause, changing the food should be fine for your other cats if they are healthy.

Q. My dog gets very loose stools
ANSWER : A. Loose stools can be caused by a wide number of things, however the most common two are internal parasites and food ingredient allergies. Internal parasites like worms can sometimes be seen in the stool, and may also cause other symptoms such as vomiting, bloated abdomen, or changes in appetite. Bringing in a stool sample to your vet can help determine if there are parasites present, and if so, what type.

Food ingredient allergies can also cause similar symptoms and are commonly caused by ingredients such as wheat, corn and soy, but some proteins such as beef may also cause it. Switching to a different food that does not have these ingredients may help. Be sure to switch over a period of 7-9 days to give your dog’s stomach a chance to adjust as switching too quickly may cause vomiting and more diarrhea.

If you still can’t figure out what the cause to the loose stools may be, then a more thorough examination or additional tests at your vet may be best.

Q. My dog is pregnant and I believe is constipated again. What can I feed her to help?
ANSWER : A. If your dog is currently pregnant, it is always a good idea to check with your veterinarian prior to giving any additives or treatments. However, pureed pumpkin can usually be given successfully to help regulate stools. The added fiber in the pumpkin can help to make stools a little easier to pass. A plain yogurt added to the meals may also be safe to give and can give probiotics to the body to make digestion easier and stools more regular. Increasing water intake by adding in a wet food safe for pregnant and lactating dogs can also help bring more water content into the body which can help ease constipation.

In some cases, diarrhea can actually be confused for constipation. Dogs with diarrhea may strain after a movement, which may appear as them straining to get stool out. If you are seeing stool that is soft or loose in addition to straining, then diarrhea instead of constipation may be the cause.

Q. My female 2yr old papillon has had loose stools & small amounts of vomiting. Somewhat tired. Can I give her something to help her? A scrambled egg ?
ANSWER : A. For the loose stool give some cooked white rice and plain cooked chicken. For the vomiting there is nothing to give and if that continues I would advise to see a vet because he will get dehydrated and may require IV fluids.

Q. Bowel movement 6 times a day. Stool is soft light brown and white. Sometimes drops of water come out during bowel movement. He seems anxious
ANSWER : A. If your pet is experiencing frequent bowel movements, loose watery stools, or stools that have changed color it is best to contact your local vet. Stools that are watery can indicate many problems ranging from digestive upset, internal parasites or even illness. Color changes in stool can indicate problems such as issues with the pancreas or gallbladder as these two organs contribute enzymes that give stool its brown color. Be sure to bring in a sample (or multiple) of the stool to your vet as this can help them quickly examine it for issues as well as check for common illnesses or parasites.
