Diarrhea. Its not the most exciting topic, but something we have all dealt with at least once. It seems Frenchies have extra sensitive stomachs, especially at puppy age. Many families bring their puppy home at 8 weeks old when they have recently been weaned from breastmilk and are still getting used to eating kibble. Add on top of that the stress from separation anxiety, and its highly likely to result in diarrhea. Separation anxiety is a whole other topic, so very briefly, it is a side effect of being separated from everything your puppy has ever known in his short life. The familiar faces, siblings, mother, sounds, smells, food, and area are all gone in once instant when coming home to his fur-ever family. The stress from this tremendous transition in life can cause many things, including diarrhea, and can even depress the immune system. This is one cause of diarrhea I have seen over many years of breeding and experience with my French Bulldogs. They need a stable, loving environment first and foremost.
Another cause of diarrhea can be sudden change in food, eating table scraps, eating rancid food, an intolerance to any specific ingredient, or food poisoning. If you think your French Bulldog might be intolerant (allergic) to an ingredient, ask your vet for an allergy test. If you are thinking about switching foods, do so slowly to avoid causing diarrhea. Mix the new food into the old food, each day decreasing the amount of old food, and increasing the amount of new food until you are only using the new food. If you think your Frenchie has gotten into something potentially poisonous which may be causing diarrhea please don’t hesitate to call your vet and get your puppy examined.
Next likely cause is parasites. It’s a bit of a nasty topic, however all part of life. Dogs like to lick their behinds, some lick other dogs behinds. Some dogs even eat feces that they find outside. No matter how clean you keep your beloved pet they are most likely carriers of parasites. Giardia (a single celled parasite) can be found in the water, and even on the grass. It will live for months in moist conditions so all it takes is your Frenchie going on a walk outside, coming home, and licking his paws. Your vet should have your French Bulldog on a regular deworming schedule. I personally deworm once or twice a year preventatively with fenbendazole for five days following my vets recommendation for dosage which depends on weight. Its very important to remember you must follow up with a second treatment in two weeks. This is because many dewomers only kill the live parasite, but not the eggs. The eggs take about two weeks to hatch, and if you don’t follow up with a second treatment then they will develop into worms and your Frenchie will continue to have symptoms (diarrhea). Not all dewormers target the same kinds of parasites. For example, fenbendazole doesn’t kill tapeworms or heartworms. The transmitter of tapeworms are fleas. So if your French Bulldog has fleas, treat the fleas at the same time as tapeworm. If you see “rice” in your dogs poop, they likely are infected with tapeworm. If you see blood in your dogs poop they are likely infected with coccidia (another type of parasite). Your vet can take a poop sample to test for parasites and give you medicine if you are not sure what they might be infected with and what to treat with.
I deworm my French Bulldog puppies preventatively with fenbendazole and albon before they come home to their fur-ever family. However, giardia particularly can be resistant to treatment and persist in the right conditions. The right conditions would be including stress, very young or very old age, during pregnancy, active disease or condition which depresses the immune system. I mentioned earlier that separation anxiety can cause so much stress to a newly rehomed puppy that it depresses the immune system. Only tender loving care, and time can help with separation anxiety. However there are other things you can do to strengthen the immune system for example feeding super premium, easy to digest food, and probiotics to help the gut. I also feed my French Bulldogs ground raw pumpkin seeds which are a natural dewormer and help to make the poop solid.
Yet another cause of diarrhea can be from a virus. Parvovirus and distemper both cause diarrhea and can be fatal. It is transmitted through contamination with infected feces and can be very difficult to treat in young puppies. Your vet can quickly test for parvo with a poop sample. My puppies come home with a minimum of their first set of vaccinations including parvovirus, distemper, parainfluenza, and adenovirus. That being said, the puppy will still need booster shots so talk to your vet about what vaccines your puppy might be due for.
If your French Bulldog continues to have diarrhea despite ruling out anxiety, food related issues, parasites, and virus I would talk to your vet about ordering a lab to check for pancreatitis. A friend of mine ruled this out in his Frenchie. It was an expensive test, but after finishing the meds his dog finally stopped having diarrhea. Also ask your vet for more recommendations, especially if the diarrhea is accompanied with vomiting and other symptoms you need to act fast.
