Hmmm....well there isn't really a need per say for the stud to play and bond with the pups. The dam will be extremely protective of her pups for a long while and aggressive (possibly) to any dog she sees as a thread to them, even the sire. The female's instincts tell her how to act around the pups...dad will just see them as play things. So in short, introducing them when the pups are young could present several possible dangers.
You kind of have to play it by ear. I would say minimum of 6-8 weeks, maybe? Act as if the sire is any other dog...not the dad. When would you be comfortable with any other dog being allowed access to them...and to mom? |
