My name is Bowie!

Bowie is a sweetheart! He is learning to calm himself down. He has had a couple of private training lessons. He needs lots of exercise and mind stimulation and needs someone with a very active lifestyle. He's very smart. He does know basic commands but needs help reinforcing them. He is super playful and excited, a lot! The vet said he'd be around 80 lbs. He will need to be socialized with other dogs as he is very reactive. He's not aggressive in any way but his bark is intimidating. He nips and plays but he is a puppy and is part Australian shepherd so herding is his "thing". Bowie is crate trained and potty trained. Our cat and Bowie do not mix well. The cat has become a mostly outside and garage cat but I am worried for the winter months coming soon. She is losing weight and hair from the stress. Please help Bowie find his forever home. He has so much potential and is very loving.
