Ok...
It has been FOREVER since I posted here. But I figured you all would know the best on what to do

I got married on July 9, we had a 17-day honeymoon and moved into our apartment on the 23rd. My Yorkie, six-year-old Bubba, moved in with us this past Saturday. When he was at my parents he had four cats and another Yorkie (Tyke) around, so I wonder if he misses his brother

Bubba hasn't eaten much at all since Saturday. A bite here and there. I am in the process of retraining him and taking him out every two hours and giving him a treat everytime he goes (which is everytime he goes out) and he will take a treat and eat it like someone will steal it in a few seconds. He is drinking. What is odd is he is having bowel movements, but he isn't eating that much

I called the vet and they asked if I wanted to bring him in to make sure he was OK, but I know it's because he is "homesick" for my parents house. They suggested putting chicken broth over his food, so I did that. He sniffs and walks away. We had pasta tonight so I dribbled a teaspoon of sauce over his food, he sniffed it and walked away. I put his soft food in, nothing. He sniffs and walks away.
How long can a Yorkie go before lack of eating will make them sick? Should I take him to the vet or is it one of those "he will eat when is hungry" things?
I'm worried! I love my dog and my husband loves him and I want him to stay with us in the worst way...but not if he is unhappy and starving himself
