I posted this on your other thread....so now I will post here.
I have been told before that the problem with this is not that they don't get along but that they get along too well. They are a little more difficult to train due to the fact that they are wondering or more interested in what the other was doing. Another factor could be that they tend to have the "pack" mentality and would gang up on other dogs.
The only time I have ever "witness" a problem was with two Akitas a neighbor owned. They fought like crazy and eventually one had to be rehomed.
If you have no problem then I would not worry about this. |
