My mother and grandmother were out walking our dog (11 yr old chocolate lab - female) through our neighborhood when a dog came up from behind them and bit into the rear end of my lab. $600 in vet bills and medicine later, we have our lab home with several stitches and drain tubes. Luckily my mom was able to get a good look at the dog before it ran off. She told me that it was light brown with some white on it, and it wasn't wearing a collar. She also said she thought it was a pit bull. After a couple of hours of searching, I saw a dog run across the street that fit the description. It went through some bushes and I lost sight of it. But I waited. The dog came back out again so I got out of my car and followed it. Watched it jump a small fence into a backyard. After watching for a couple of minutes I saw someone let the dog in the back door of the house. Took note of the address and headed home. We contacted animal control, and an officer came out to take a report. He informed us that because of the extent of our dog's injuries, the other dog would likely be classified as dangerous. For this area, that means that the dog would have to have a muzzle, insurance, proper fencing, etc. or else they'd put the dog down. The decision on whether or not the dog is "dangerous" would be left up to his boss. Well, we heard back from him today and apparently they aren't going to be able to classify the dog as dangerous. "Potentially dangerous" will be the classification. The fact of the matter is that this dog is dangerous, and it is not safe to be have the damn thing running freely through the neighborhood. What would you do?
