I have 3 dogs in the pen with my 2 deer. A golden retriever, great pyranees, and a 1/2 lab 1/2 pit. THEY ALL GET ALONG GREAT!!! When I first bought Faline (1 wk old) home - I had 2 dogs, I kept her in the house and brought in each dog in 1 at a time and introduced them. She was fine - the dogs wagged their tails and sniffed her. Two yrs later, I bought Nina home (2 wks old), about 3 weeks prior I had purchased Kane (great py) he was 9 wks old when he met Nina. Nina and Kane grew up together - he was too small to let him run & play with Faline so I kept him and Nina in the fawn pen for a couple months. Two years later they are still BEST friends! When the other 2 dogs are laying together and the girls are laying together - he goes with the girls. He is an awesome guard dog. It's funny, he lets Nina do whatever she wants, but sometimes he gets bossy with Faline. For example, there have been a few times when he lays on the deck - when Nina walks onto the deck he doesn't make a sound he lays there and looks at her, but then Faline comes along and he jumps up and barks at her. Weird.....
