Hello, My border collie is 1yr and 8 months old. He's just about perfect apart from recently his dog walker has suggested getting him neutered for the reasons he is underweight and he shows some anxiety before going in her van and my car. And a bit of misbehaving when he's out with her and the group of dogs. He weighs 16kgs and the vet says he should be over 17kgs. The vet also said he doesn't need neutered. But she did not ask many questions about his routine, walks or diet. So I feel it was quite an uninformed answer from the vet. My dog is mainly anxious before he goes out with the dog walker. Not so much anywhere else. He runs after rabbits and squirrels sometimes and wont come back until he loses his focus or manages to herd them all the way back to me. But then he does come back every time for me (not for the dog walker though). At the same time I've walked right past flocks of sheep with him and he's just stuck by my side without running after them. Just to emphasise, I trust the dog walker and she has never gave me bad advice. This is just my way of making a more informed decision to get my dog neutered. Should I get my border collie neutered?
