I haven't been on Yorkie talk in a little while. School and Jack take up the majority of my time. Anyway, the reason for the posting is I think that something is wrong with Jack. For a couple of days now, I can hear Jack's tummy rumbling. He seems to be acting fine but it is really loud. When he uses the bathroom it is pretty normal. However, it did use it this morning and there was like a yellow liguid to it. (Sorry for the graphics). I changed him to adult food about two weeks ago. It is the same brand and everything that he has had for the last year so I don't think it is that. I am just not sure what to do. Should I take him to the vet?
