I you dont feel right find another one. your feelings are most likely right on.
Jess broke her leg and I brought her to my vet who put a cast on. 5 weeks later she tells me "It didnt work at all I think we should amputate" I almost passed out in the room and had to walk out. She looked at me like I was insane...I said "not an option find another one..she reluctantly sent me to a surgeon who was wonderful. I was told by two other vets they NEVER should have put a cast on the leg, it never would have healed that way. She is fine now..that vet? Not mine anymore..
Go with your gut!!
