Ok, Mack started out as my dog but has recently went to a different more experienced owner due to severe aggression problems. We got Mack when he was 7 months old from what I believed was a good breeder, who turned out not to be so good afterall. He had no social skills, had only been outside 2 times (this includes going potty), no housebreaking skills, and only one puppy shot. He was so sweet to begin with, always wanted to be by us, was always really gentle and sweet with our daughter. He was nuetered around 9 months and we thought the few housebreaking and aggression problems he had would go away, but they didn't. For awhile he was good (about a month) and then the housebreaking problems came back worse than they ever were. Then a little before his first birthday he bit me very bad. He stayed at the shelter for a day and my husband bought an outside run and brought him back, desperate to work with him. About a week later Mack bit me agian and caused me to get serious stitches. This time we knew he had to go, and a man stepped up and offered to help him. Well things got worse there and he ended up going to the animal control, by their request (either the guy dropped him off or they would come and get him). Well unfortunetely, or maybe fortunetely, Mack was euthanized yesterday as they felt he was too unpredictable to try and adopt out agian. He was such a good dog, and it's a shame he had to have such a short life, but that's what happens when you go with a backyard breeder. PLEASE don't buy from backyard breeders, you might be getting a deal at first but in the long run these puppies are not a deal. RIP our sweet boy, go join your sister Shelby she's waiting for you.
