The past 2 or so weeks Summer has been leaving kibble in her bowl quite often. She'll eat maybe half of what she usually does. I was watching her today and hand feeding her kibble (training) and noticed a lot of times she would take the kibble and then spit it back out. It would look like she would move it to the back of her mouth then spit it out. I'm wondering if I should take her in to get her teeth looked at? It almost seems like a tooth sensitivity on a molar to me. But then I think I'm probably worrying about something that is fine.
