Hi, i am new here, read lots of useful information already! Up until last December, we had 3 dogs, 1 male, 2 females. The male was a GSD and had to be put to sleep just before Christmas when his health failed him. We have just taken in a new GSD, about 2 years old. My females are 5 and 8. He has settled in here very nicely and for the most part, all the dogs ignore each other. We are introducing them slowly, have taken them out for long walks together. It doesn't matter whether we are at home or out on a walk, the new male will sniff at one of the girls, circle around her and then grab her by the neck. There is a bit of snapping and growling but no blood has been drawn - yet! obviously, we cannot leave them alone unsupervised for the foreseeable future and wouldn't put any of them in a situation where they are uncomfortable. My question is this - is the new male attempting to assert dominance? If we didn't pull him back when he grabs the female, would he do any serious harm to her - that may sound like a silly question but I don't want to interfere in any pecking order issues. All three dogs are obediant, even the new one and he already looks to us for commands. We have never had this problem before because we always introduced puppies, never older dogs.
