We have two male collie x's and their 2 but there both quite unsociable & today we got a female lab puppy, when we brought the pup into the boys the started barking and growling at her. so we have just been letting them see her through a gap in sliding doors now, is this normal? Will the get used to her? Do you think they would attack her?

How old are the boys? Are they neutered? If they are known to be unsociable how come you ended up with a puppy? It is always best to sort out the problems one already has before adding a new one :-)

Can you tell us a bit more about how/where you introduced them - was the pup on your knee? Were you somewhere that the dogs would regard as "theirs"?

there 2, and yes their netured, we got the puppy because their fine with female dogs normally, but this time it seems to be different, they just gott out a few minutes and terrifyed the poor pup, At this stage were wondering are they to dangerous to have if they were to snap at a person like that and do we get them put down? or do we find the pup a different home? They've barked and just up and people before and on walks they dont like people approaching them but they were like that as puppies too, we got them when they were only 6 weeks old which was far to early and it seems that there very protective of the home & family over this..
She was being held and it was in the hall when we indroduced her.

Much of the problem with introducing new dogs is that existing dogs catch the scent of something alien in the house. By not letting the existing ones see the new one, take the new one in and bath it with the same shampoo you use on the existing one which helps hide the new scent and replace it with a scent they know. Keep them separate allowing viewing through a pen or crate area allowing each to view the others this way so that one is not kept crated but swap them out allowing for the new one to have time to move around unobstructed and then do the same with the existing ones.
Though they have already seen the new pup, the scent is still there. Try the shampoo and see if this helps a little.
