A couple months ago, he started limping and
having seizures. Turns out, he has arthritis in his hips and
was showing early signs of prostate cancer. He wasn't neutered so my mom got him neutered to save his life. Now, he's EXTREMELY aggressive. He constantly does this growling-bark thing to everyone, including the 6 people who live in the house. He has lunged at myself, my stepdad and my mom. He was NEVER like this. He did however, barked at everyone.
