Really, only a vet can help Buddy. We are not vets here, only pet loving people.

I have been to a vet twice, blood test taken, x ray taken, says swollen back joints, gave dog medicine, still no better. Spent so far over $500.00
I say now what for my poor dog.

What medicine did he give? Anti-inflammatory pills?
