That's surprising that the lab is aggressive. I always found their temperament to be close to a Golden's. Although, having said that I came across one that was real protective at the dog park the other day. Towards other dogs though, not people. They were trying to get him used to the park, with a leash. Didn't let him run loose.Across the street neighbors have a young chocolate lab. He's starting to become protective of their property (especially when their daughter is outside). I get it, but when he starts challenging me on my property that's a problem. Yesterday when I let Maggie out he was on our lawn and started growling at me. Maggie let out her fearsome growl/bark and charged at him. He went home in a hurry. They have invisible fence because the in-laws used it to control Teddy an aggressive pit/chesapeake retriever cross. Talked to the wife, and she realizes the dog is a problem, but her husband (he's a veterinarian) doesn't want to use it. I explained that there are two possibilities: the dog may get hit by a car and killed or the dog may/will bite someone. I also explained that if the dog bites the Princess, Maggie, or me we will have a significant problem. Joggers, bicyclists, walkers with kids frequent our road. It's a problem easily resolved BEFORE it happens.![]()
