I think Nemo is potentially having some sort of tooth-related issue and I'm curious if others have seen this set of behaviors, possibly in conjunction with dental issues.
Recently, after he eats dinner, usually kibble or sometimes raw food, he has started rubbing his muzzle on the ground back and forth (both sides) and will also paw at his face several times. He has also been sometimes slow to eat his food or won't eat it at all (mainly if it is kibble, and very atypical for him). If I soften it with water he will eat it. It doesn't appear to be an appetite issue. If it is something extra yummy, he will
Historically he has pawed at his face or rubbed his muzzle on the ground occasionally after he ate something messy but I don't think that is the same as what is occurring now. Particularly as it is in combination with the non-eating issue.
I took him to the vet today and there was nothing obvious to note in the exam. There is some gum recession on one of his very back teeth but it wasn't mobile and did not cause a reaction when the vet pressed on it. Rather than doing an X-ray, we opted to try a round of antibiotics and watching to see if it gets better over the short term and then returns again after the course of antibiotics is complete. If that happens, then we'll pursue the x-ray to see if it is something like an abscess.
