I had a bad experience with my 1-year-old dog at a dog park recently. She is a pitt mix. I adopted her at 5 months of age. I had been going to puppy socials at the pet store every weekend with her. She loves other dogs and people. Only problem I saw with her was jumping up on people, which I am in the process of breaking, and working out pretty well with that. Now the problem I encountered this week. I am very disappointed to say I found out the hard way that she is not dog park material. On her 4th trip there (the first 3 were okay, she was a little over excited to see new dogs coming in), she lunged at a smaller, timid dog and had it by the throat. I had to use my hands to release her mouth from the dog's neck. I didn't see any injuries to the dog, people were very upset, I got the leash and removed her from the park. Havent been back since. I called the city dog park office today just to see if there any complaints filed, I didn't say who I was because I wasn't asked. The clerk said there were 3 complaints filed so far about this incident and she gave me her email address if I could send her an email describing what happened, a description of the dog and its owner, but she had the dog's name right. She said they would try to look up the information on their system (which I find strange because they have all the information when I registered, I'm surprised I havent been contacted yet quite frankly). She also said a police report may be filed. (?) I asked if anyone was injured, and she said no (big relief on my end, because I couldnt tell by looking at the other dog if any damage was done. The owner carried it out of the dog park after having a few choice words with me.) So now I'm waiting to see what happens next. This is so devastating and I feel badly for the other dog and its owner. I do NOT intend on returning to a dog park ever again. Anyone ever have something similar happen to them or someone they knew. I just wonder what I'm in for. And I'm not defending my dog, I never thought she had this in her. There were a few other aggressive dogs there as well, but not to the extent that she carried this out. I'll say one thing. On my first visit, I sensed people didnt like the fact that she was a pittbull mix. When I registered her, they didnt have any breed restrictions, and they knew what breed she was.
