That is the weirdest thing I have heard lately. Early sex is different than early neutering. Just because he looses a few million sperm cells doesn't mean he loses his testosterone.Early sex will stop his physical development altogether, when he could grow bigger, bulkier (and more intelligent) otherwise.
What are your medical references for this one?. Early sex will stop his physical development altogether, when he could grow bigger, bulkier (and more intelligent) otherwise
Oh, now I understand how they developed the toy breeds; they just let them mate at 6 months! Ha, ha, April fools day is long over. I am curious which study you are quoting.If the sperm wasn't spent, the organism economizes on its production and the energy is used for further development of the body.
Oh boy...where to start...A German Shepherd male should be older than 2, that is AKC standard for the show line. But that mainly concerns the dog's health checks. In the working line the male age for breeding is 3, only then the dog is fully tested, it is physically impossible to get that many diplomas for the breeder-handler with a single dog.
