Connor came to Colorado Top Dog with severe separation anxiety and was very aggressive to start. He required behavior modification. Corey spent 5 weeks working with Connor. Now an amazing pup. You’ve never seen a short dog fetch so well and fast. He’s very dynamic. Has a great heel, down stay. Stays on his bed well in the home, even at dinner. This was Colorado Top Dog’s first opportunity to work with a Cardigan Corgi. Needless to say, they’re fun dogs!
