None of my dogs have been aggressive. My spouse got a small dog and yes, for the first year, he was hell to deal with, BUT my spouse enrolled him into a training class and every single day he made improvements little by little. It took a full year to get him tamed down and we had to seek a doggy psychiatrist. That was really expensive, but it worked thank God‼️‼️ My spouse and I got a look into his past. What we found was absolutely heartbreaking‼️‼️🤨😡😢 He was being trained as a bait dog. Someone with a soft heart took him out of that situation and took him to the shelter my spouse rescued him from. I’m so glad we rescued him and gave him a good home and a good life. He’s still with us and I am very grateful to the person who helped him out of that horrible situation. Also, when we first got him, he had no idea how to play, he didn’t know how to eat out of a bowl even‼️‼️ We had to teach him how to eat and drink water from bowls. Like I said, it was heartbreaking ❤️‍🩹 ❤️ We got past all the trauma!! He’s great now and he’s happy.
