Hello,
I was wondering if anyone could tell me from experience how othe dogs react to the arrival of puppies.
I have a boy and I want to be prepared to keep him away from my girl and the pups if necessary. Will he hurt them? Or will his presence possibly upset my girl? I'd be extremely grateful for any advice :0)

Definitely keep them separate whilst she is giving birth and for a few days afterwards - after that she will let you, and him,  know whether she wants him near or not.
