My dobermann male is 6 1/2 months old and my friend has a 2 1/2 year old bitch Rottweiller. Since my puppy was 12 weeks he has been mixed with my friends rottweiller, but she has always growled at him and tried to dominate him. As my dobe has grown she doesn't seem to lunge at him as much but she still will growl and try to have a go at him. On Monday we went for a walk and she kept having a go at him and eventually after a few times he then had a go back and they were up on their back legs and seemed to be fighting - they were growling and snarling and biting at each other's mouths. I would have thought that a male puppy and female dog would be okay together. This happened about three times while we were walking. She seems to instigate this all the time, what is the best way to handle this?
Most of the walk they get on fine playing and jumping about!
