I had a corgi that had watery stools, diarrhea off and on from the time I got her at 10 weeks old. It didn’t happen every day but at least once a week.
At the time I could not afford to go back and forth to the vet. Don’t think I had much testing done other than routine. Tried different foods, nothing seemed to make a difference.
At age 9 months it just stopped completely. She was fine for the rest of her life. Cancer got her at age 9+.
PS: In retrospect she probably had some kind of a bug, that’s why your vet wants to try medication, antibiotics panacur, tylan. I would go along with it.
