Ryker is a handsome, high energy 2.5 year old brindled, male Mastiff cross who came to us from Manitoba. Ryker is a very busy dog. He is always exploring and investigating. He is very food motivated and this is an effective way to help him improve his obedience. Ryker reacts to other dogs and today he is walked away from other dogs. He is very strong and weighs about 100 pounds so dog and squirrel sightings can be a challenge. Once Ryker bonds with you, he is trusting and affectionate and also protective. He is house trained, crate trained, knows sit, paw and down and is working on heel. He needs positive reinforcement on his leash manners.
