Blue is a neutered, 3 year old ACD. He is up to date on all vaccinations and health checks. He does have luxating patella, which is where his knee caps can spontaneously pop out of place, it is not an emergent health problem and he has learned how to correct this when it does happen. Blue is a more calm ACD but does love to play and get lots of love. He has been raised around other animals including dogs, cats, rats, horses, and poultry. He will try to bite horses out of fear, will try to hurt poultry and rodents, and actually has killed an opossum and a racoon, and will chase outside cats. He is a dominant dog with other dogs and can be toy aggressive, food aggressive, and water aggressive with other dogs. He can get grouchy with other dogs as well but has lived in a home with another dog his whole life but needs to be watched and corrected for negative behavior. When it comes to children he gets anxious with hyper children and will try to nip them, he does usually give a warning growl when he doesn't want them by him. He did just recently nip at my 7 year old son's face while my son was petting him gently, and I believe this is because Blue was lying in his bed and can be territorial over his bed/kennel. He is kennel trained and needs to be in the kennel when nobody is home as he will chew things up. He has had professional training to help correct these behaviors and will still need more work. He is a very loving dog and very loyal, but I do feel the best home for him would be as the only animal and without young children. He picks one person as his person and will be their shadow and will be somewhat territorial over this person, if he doesn't feel a threat he isn't aggressive, but he is skeptical with strangers around his person. I have taught him many basic tricks and he also knows heel. He would come with a fresh bag of the food I currently have him on for either keeping him on that brand or to help with a transition to a new brand, has a chip that I would transfer to the new owner, and I have all vaccination records and vet paperwork to go with him as well as training history. I would include his favorite toys, collar and leash, as well as his harness and muzzle, and his kennel and his bed. If anyone has any more questions please feel free to contact me.
