I have a 5 yr old pitbull who won't gain weight.
She's been vet checked, no worms, she's active, eats well, but she is very skinny. She gets two cups of dry food and a can of wet food with it twice a day. I've tried different foods with her but nothing has worked. Eukanuba, canidae, etc. I've given her ground beef with rice three times a week along with her regular dog food but she hasn't gained a pound. My 6 yr old daughter even sneaks her treats throughout the day. I do know that her previous owners abused her and bred her before she was a year old. The vet says she is fine at 52lbs but I can see her ribs so I'm not sure.
