More: We rescued Rolo in April of 2021. He was 4 months old when we got him and we were not sure he was a pure Lab, so we ran his DNA that proved it. He would bark, bite and was not potty trained. We nurtured him, took him to our lovable trainer 3x/week and did exactly what she said. He is the most mellow, kind and smart doggo now!!! Everyone told us the chocolate labs are so crazy, but he is not. And he's a big boy at about 90 pounds! I love him, and I never worry when he's with me because he is the big protector!!! My mom passed away in May, but we still tell him we are going to Grandma's pool and he gets so excited!!!
