I have two dogs. A chihuahua named Tony Stark, one and half years old. He's half short hair, half long hair, so he's a little scruffy. And a mix female, chihuahua/papillon/pomeranian/a few others mentioned I can't remember, named Casey. I think she's 7 or about to turn 7. Also very fat. We got her spayed last year and she just ballooned. We've got her eating less and exercising more, but she hasn't lost even the slightest bit of weight as far as we can tell. Vet says she's healthy aside from being fat, though. I'm at a loss.
