Nia had this problem for the first time when I put her on EVO red meat. She's come back from peeing and start licking herself to clean the urine off but then she'd lick for a really really long time (5-10 min) and grunt and then make this thrusting motion as if trying to get something off her potty area and continue licking.
I thought it must've been the EVO since the problem started 2 or 3 days after I started that food.
I switched her to Orijen Adult (she did fine on it) and now we're on Orijen 6 fish again. The same food she was on before she became itchy in EVO. She's been on it for...I think 2 months now, and the last few days she's doing it again. Licking, thrusting, licking more.
Last time I went to the vet and he said she doesn't have a UTI and since she wasn't licking when we were there, he didn't really know what was wrong.
What should I do? Should I take her off high protein food and try some regular protein stuff? She's done so well on high protein though, happier to eat, shinier coat...
I don't understand why it would become a problem now since she's been eating Orijen for more than 6 months (in total) without any problems including the fish formula.
Edit: she is spayed by the way so not a heat related thing.
