Canine Behavior/Introducing a new dog


Hi, I own a lovely staffy/boxer cross bitch. She is a really wonderful gentle dog. She is a rescue of about 3.5 years age an we have had her since she was about 1
So when we saw of another staffy/boxer cross of around the same age in arescue centre (even though we wernt looking for another dog) we decided to get him. He is also a really lovely dog and extremely gentle and full of affection just like the bitch.
The problem were having with them is that although they are generally fine together during the day or night, intact they often share a bed. When were home The bitch which is the original dog will follow him round the garden nipping at his Jowls. The dog is very submissive but has started to stand up for himself causing them to fight. A couple of times they have even drawn blood. I believe part of her behaviour could be jealousy over the new dog been in her garden etc. is there any good methods for stopping them fighting. As iv read up on it in a few different articles and they are often slightly contradictory. It seems so sad to have to give this lovely dog up when they get on 95% of then time. We have only had the dog 5 days and we was just going to see how it played out and hopefully calmed down between them but the one thing most articles agree on is that this aggressive behaviour will often just get worse between them. I would be very grateful for any information you could provide me with.

Dogs were introduced improperly (no reflection on you, how could you possibly know what to do.)  After only five days, you're having trouble.  You need the intervention of a behaviorist and in the UK there are many licensed professionals.  Before this gets worse (and it might), do something.

Here are some resources:

Meanwhile: identify WHERE and WHEN the problem arises and keep the dogs from repeating in these situations. Do not allow the bitch to follow the dog around in the garden.  He is being a male, he is acquiescing, but her behavior is pushing the issue and then reacting in a manner that causes me some modicum of alarm because the dog almost always acquiesces to the bitch.  You have no history here, this male might not be habituated to another dog; your bitch might not have been habituated to another dog.  I can't see anything from here.

Can this be de-escalated?  Yes, I have done so in situations with same sex aggression (much more treacherous).  It can be done by the "right" person but that person absolutely requires solid credentials and references you can CHECK.  I think there's hope in this situation but you must act, and soon.
