I don't know-she seems to scoot in such a random manner. I kept a log for about a month and could never find a pattern. She had fleas and that was a factor, then we took care of that and now we're trying the food allergy thing again. I thought it was environmental. Wouldn't you think that if it was, let's say, the peanut butter, she was reacting to, it would happen right after eating the "offending" food? Nope! I guess that would be too simple.
The vet said-feed fish and sweet potato, duck jerky and not the oatmeal cookies. I give her her pill with peanut butter.
I don't know???
