The French bulldog is known for allergies.
The biggest cause is their immune system didn’t develop properly leading to food allergies. I always recommend you start by changing your dog’s food to see if this solves the issue. We suggest no grain dog food that is chicken or beef based. It’s cheaper to feed them good food than to take them to the veterinarian.
Recently, one of my customers called to advise me they were struggling with allergies with their frenchy as well as their other dog and asked for help. Since I haven’t experienced it much, I reached out to an online site for other frenchy owners. The overwhelming response from all of them was to add a cap of apple cider vinegar to their drinking water. Evidently, it helps with allergies as well as fleas and ticks. Hope this helps.
