I have two dogs: a 4 year old English Mastiff that weighs 210 pounds and a 3 year old chocolate lab that weighs 140 pounds! We are having problems with the lab, Mac. We walk our dogs almost every day, but Mac has continued to drag us on walks so we can only walk when my husband is home. When he sees people or dogs coming toward us, he charges toward them. He will not listen to commands at all. We try to stop him and make him sit, but he just charges on. At 140 pounds, it's impossible to stop him. He is usually friendly once he gets to the dog or people, but the other day the other dog lunged at him and they were snapping at each other. When we finally got to the park and let him off leash, he ran to a couple that walked into the park and started growling at them. I think he has territory aggressesion, as he barks at everything he sees outside the window - people walking or driving down the street, people (even us) coming in the door. He will not stop or listen to any commands when he gets excited like this. I'm at the end of the rope. We tried the gentle leader head collar, but he scraped his nose on the ground and made it gush blood. We then bought the Gentle Leader Easy Walk Harness, which has helped the pulling, but I'm still worried about his aggression toward people and animals in his perceived territory. Any suggestions? Your help is greatly appreciated.
