I've had issues with her barking at other dogs in the past. I can't figure out why she barks and goes nuts at some dogs, and she's friendly, fine, and happy to play with other dogs in our complex. For the most part I try to just keep her away from other dogs. She will bark and start going crazy, spinning around. I bought the book "Click to Calm" so I can read it and try to help her. She's not reactive with all dogs. I just don't understand it. I've taken her to dog parks before and she's fine with the dogs there. Runs around and plays, and she's good. Get her around a dog when she's leashed though, and she freaks out. She's gotten in a fight with a dog before where the other dog bled, but that wasn't our fault. A dog that was completely off-leash, with a history of dog aggression, attacked us and she defended herself. She also scuffled with a dog who was off leash and came up onto our front yard before. She's territorial, and when the dog got off of our lawn, she stopped. So.. yeah... she's had scuffles with other dogs before. I don't know how to stop her dog aggression, so I just do my best to minimize her exposure to other dogs. Unless it's a dog that I know she gets along with, I ask people to keep back with their dogs, and when we're walking anywhere and I see a dog ahead, we turn and go the other way. Not sure if that's the best way to handle it, but it's what I've been doing right now until I can figure out how to handle it. Anyway, so yeah. Juno bit a dog today. I took her out to the bathroom and was standing with another lady, chatting, while Juno did her business. Juno was standing next to me calmly and I bent down to pick up her poo and she suddenly charged away from me, ripped the leash out of my hands and took off. There was a lady walking her dog past on the level below us, and Juno ran up to the fence and barked at her, and then ran around the corner, where the two levels meet up. In the past when she's encountered dogs that she barked at she's stopped and sniffed them. She just lunged at this dog and bit her. I caught up to them at that point and pulled her away and she calmed right down and stood there. I don't know if she hurt the dog. The owner pulled her dog away, put her dog in her apartment and then came out to talk to me. Juno pulled a tuft of the dog's hair out. She said she'd check over her dog and see if she was alright and let me know if her dog needed to go to the vet. She hasn't come over yet, and if her dog was hurt, I imagine I'd have heard about it by now. I'm terrified animal control is going to come out. She isn't registered right now. I didn't renew her registration, which is stupid I guess, but it expired recently, and we're moving out of state in three weeks, so I just didn't see the point in paying the fees to register her again. When I move, I'll be in a bit better of a financial position than I am right now, and I've been intending on getting her more training when I'm up there. I also think I'll be in a better position to work with her on training, because right now, I live with two other people who don't reinforce anything I'm trying to do with Juno, and as a result she attention barks a lot, and can be really pushy. This has gotten long and rambly, sorry. I'm just worried about my dog. She's my responsibility and I feel like I'm letting her down. I can walk her with a muzzle, and make sure the leash is firmly wrapped around my wrist, but it won't fix the underlying problem.
