I need to find a new home for my dog Gunner. He's so sweet and I love him so much, however, he is aggressive towards other dogs. He does not get along with our other dog Charlee, and this makes our living situation very difficult. If you have or know anyone that has room for him to run and a good home, please reach out. Gunner is an 8 year old Aussie. He is incredibly healthy and never had and health problems.
