at what age do male german shepherd dogs can start breeding?

At 1 year they are sexually mature, but when it comes to breeding, it is best to wait until year two, so the pups can be healthier.

Usually it comes around six months of age whenever or whenever their balls drop.

Have your dog neutered. You aren't an established breeder, and there are enough pets being destroyed every day in shelters and pounds. If you do it properly, you won't make any money, and it's not a good get-rich-quick idea. Just neuter your pet, enjoy him, and leave it at that, please.

It is best to wait until they are two so that they puppies are healthy.

Not until after he's 2 when you can have his OFA and eye CERT tests performed to make sure he's a quality stud.BUT - If you don't know the answer to this question, then you shouldn't be breeding at all!

around one year !
