At one time I had two hunting dogs (Brit and Gordon setter) and a Pit mix house dog.
All of them were socialized with neighbors dogs and I never had any issues with them attacking other dogs or any aggressive behavior.
Two years ago, I had to put my Brit and Pit down.
Since then, my Gordon who is 13 and 80% deaf, is a total mess and very unstable with other dogs.
I was hunting grouse in VT last year and I let him out to do his business, but he decided to attack the puppy of the land owner as he was walking her across the property.
Since then, he's been on a short leash and I don't hunt him with any other dogs.
I have no tolerance for owners that know their dogs are aggressive and let them run free to be aggressive.
