I've got a 7mth old Nova Scotia Duck Tolling Retriever. He's just a family dog, but is from good showing background (I won't be showing him though as I don't have time) I do take him to the local toller group, run by the breeder that he came from, and there's a possibility that I could breed from him if I wanted to as he's turning out well. I've also got friends with a young collie bitch and they'd love to breed their bitch with him when he's older as they think he's a lovely dog and they'd make gorgeous puppies. It'd be lovely to have one of his sons/daughters in the future, pedigree or mutt! but I've also heard that if male is only bred once or twice he can become very frustrated and dominant as he knows what he's missing and to keep him entire and not breed from him can lead to bad behaviour. I've been told it should be done before he turns 1. I wouldn't mind not breeding from him, and I've heard its healthier to get him neutered. At the moment he's pretty good, does try to hump his bed and some other dogs but is fine with people, but he's only 7mths and has only just started cocking his leg. What do others do? I've never had to make this decision before as my other dogs have been rescue dogs and were neutered when we got them.
