When i rang about her injections she said was I going to breed her. When I said no she said they spay them at 16 weeks I said to her that was quite young. She told me the younger the better for her. I said I had heard its best to let her have her first season, she just said it was an old wifes tale as was letting them have a litter of pups first. I did say I would have a chat with the vet when she as her injections.
