Territorial & Dominance Aggression
We have a large fenced property in a rural area with 4 dogs and 2 inside dogs. Of the 4 outside dogs one is both Territorial and Dominance Aggressive. He is a mixed Golden & Retriever, very large and about 13 months old. He has been with us since we found him at about 5 weeks old and has always been around the other dogs on the property. He is the pack leader even though Boots our mix doberman/rottweiler (female spade) is more food aggressive but only with Blue and another male dog, Tux a Black Irish Setter mix. Blue demonstrates his dominance by putting his paws on all the dogs, Paws on any adult's shoulders if sitting down low or wraps around your legs. He is also constant barker when something happens outside our property like a car or neighbor walking or other dogs are outside.
The big problem is that another neighbor has 4 dogs, one a male (Kirky) a little older than Blue and of the exact same breed background. This neighbor is not here regularly so they are loose in the area and other neighbors feed them. They are good to have outside the gate as security and are all friendly to people and dogs other than Kirky and Blue who always try to fight through the gate. So I know the problem, I know to work with Blue on commands but most information I find says to work with the dog and his problem (dog) who is not always at the gate. And of course when he is I know from the barking which may not be at training time. Does anyone have good experience with solving this type of problem? Professional training is not an option as we are too far away from these services
