Sorry Rini about the name mix up It sounds like you love your Buster very much And what a loving friendship he shared with little Angel. I'm sorry he had to lose his little friend Like Candy said, I think the best thing to do would be to have the vet check out Buster. He or she will give you some helpful advice, I'm sure. Please let us know how he's doing, ok?? He's sounds like he's been a very loving best friend to you!!
