Caution when Spay or neutering your dog!
We were told a few weeks ago by a champion breeder that it can be harmful to spay or neuter your dog before they are a year old. I don't know if its really serious though.
We asked the vets why this was and they said that it will cause their bones to not fully develop. So they will be thinner than normal. (again I dont know how serious the vet said it doesn't usually cause problems)
Though plenty of dogs get this done before they are a year old and they are fine, know that it can cause weaker bones. And weaker bones means a higher possibility of breaking them.
