Hi Lori,
I think you are referring to Candida when you say you think your dog has yeast overgrowth inside his body. Candida normally an innocuous inhabitant of the bowel can invade other areas. Occasionally a dog can get Candida in the urinary tract, seen secondary to Diabetes for example. Candida inside the body is very rare and almost always occurs secondary to some other illness. You’ll have signs like fever, abdominal pain, weight loss, lack of appetite .. these dogs are very very ill and usually die.
That said some years back a few loud voices attributed a myriad of problems including allergies to “yeast overgrowth” in the bowel. The idea has been abandoned by nearly all medical personnel because there are no medical finding to support the concept. A few people are holding tight to the idea despite lack of evidence that it occurs.
There is so much misinformation out there….be careful when researching as it is easy to go down the wrong rabbit hole
