So Spy used to have a pretty nice heel, but I've noticed it get sloppier and sloppier over the last couple years. Now that I am toying with the idea of competing in something, I want to bring his heel back up to snuff What I have noticed: 1. He is quite pushy and ends up a little too far ahead of me and kind of steps on my feet, it's almost as though he is bending around my legs to get in front of me I like that he is eager and motivated, but I know he should give me a bit more space and not 'bend', so to speak. Should the dog's snout be in line with my legs? What exactly IS the correct position? 2. He sits when I stop, but I have noticed his bum swinging to the outside a little. Is there a simple way to improve this? Thanks!
