What is the right age to have my pup neutered. I have heard different things..like 6 months..etc. but I'm not sure when I need to get it done. Right now, he is 2 months and 3 weeks, and has an appointment with the vet for his vacs. next week. I guess I could just ask her then, but I thought I would go ahead and find out. I know she appreciates it when I know what shes saying and I don't have to ask questions about every little thing, haha.
