Please help I'm having trouble training my puppy Benito .. He's about six months. I take him outside every morning and we take him out several times a day. We have an eight year old Boston named Bella so we try to take them to the park and play with them for a day of fetching a ball besides their daily walks. Benito sometimes participates with her but doesn't run
fully to catch the ball. We feed him eukanuba twice a day and we also take them to the dog park at least a couple times a week. Benito is stubborn and has poor listening skills. He will choose to go to the bathroom in the house after we have just taken him outside. They have millions of toys and bones but he will find other objects such as shoes etc to try to eat or destroy. He also will go in the garbage if given
The opportunity . He's learned sit but he's hyper active jumps and tries to steal everyone's food. Please help!
