Two dogs

Question
I recently adopted a 2 year old pitbull who did not have a good home. She is a very sweet dog, gets along with cats, children, and other dogs. I also have another 4 year old pit/boxer mix who is living on the west coast with my girlfriend. The pit/boxer mix is also a female and she's a very sweet dog too however she tends to be dominant of other dogs. Both of these dogs are nuetered. my girlfriend will be bringing that dog with her when she comes to visit me in two weeks. I am afraid that these two dogs aren't going to get along since they are not puppies anymore. What advice would you have for me in this situation? I have a second home setup for the 2 yr old pitbull but I really don't want to see her go

Answer
Hi Brad.

I suggest taking the new dog to a new home for a few days until you get them used to each other.  Have them meet at a neutral place and take them for a walk together, but a couple of feet apart.  After they are tired, let them smell each other.  Do this a couple of times and then bring them to your front yard or an area that is at your house, but not the pits favorite area of your house.  

Do not give praise or treats to either dog as it will bring out aggression and competition.  Also, get to know your other dog all over again before you have him meet your dog that has been living with you.  You want to have trust built up again.  It can work out if you are patient!  

If one of the dogs shows real aggression, quickly show them you don't like it and it is not acceptable.  Don't show favor to the dog that was being dominated either.  It will just breed more jealousy.

Hope this helps!  Feel free to follow up if you need to.
