Would you breed off a 12 month old pup?
no, but you can, and if dogs were in the wild and come in season it would get mated, age wouldnt come into it. dogs dont know how old they are do they.
No wild dogs going to live past 8 i wouldnt of thought,Plus in the case of wolves only the alpha female breed,so if it aint strong enough to hold top spot it aint breeding any way.Personally i would push it to8 if the bitch was fit.
