I have lost a dog that looked like a rot in much the same way as you. It showed up in our yard one summer when it was 100+ degrees out, and did not leave. The dog was very sweet and playful and very much wanted to please you so she would do almost anything you told her to. Since she had showed up in our yard we had no idea if she had been fixed or not, so the vet told us to watch for her to go into heat, and if she did bring her back and he would fix her. Well sure enough she went into heat, and we had her fixed, but while this was going on, there were so several neighborhood dogs who were continually getting out and tearing down our fence, and I was having to repair it almost daily. The local dog catcher new the storey behind the dog, and the reason she kept getting out because of the other dogs. Though he would drive past our house 5 or 6 times a day just looking for her to be out of the yard, several times he brought her back into the yard, but yet he never did anything about the other male dogs that were tearing down our fence, one of which belonged to a cop that lived around the corner, and yes he did see the other dogs our on several occasions but totally ignored them. One day she got out, and had only been out for a matter of a couple of minutes before I realized she was out, though during this time she had gone around the corner and the cop saw her out and instantly notified the dog catcher. When the dog catcher got there, they through the dog into the back of the truck, and she growled at them because she was in pain, because she still had her stitches in, as it was only a matter of a week and a half or so after she had the surgery. So the cop decided that she was a viscious dog, and told the dog catcher he was filing a report on her, which he never did. The whole time that was happening I was out looking for the dog, and calling her name, trying my best to find her, and I am sure that both the cop and the dog catcher were able to here me. After a few minutes more the dog catcher showed up at my house telling what had happened and that he had to take the dog because the cop had filed the report, which ne never did, and the fee to get her back out of the pound was going to be over $200, which we did not have the extra money to pay for it. The whole time the dog catcher was on the rude side, and had nothing better to do them drive around my house 5 or 6 times a day just watching for my dog to get out. I had the dog for maybe 4 months, but in that time I had grown very fond of her, as she was always very playful, and loved to wrestly, play tug of war, which she really got into, and just run around at your side, no leash neccesary because she wouldn't leave your side. Yes, you can legally have a dog out without a leash if she is under your control and follows your commands, which she always did. This was several years ago, though I still hate the dog catcher, and yes he is still employed by the city.
Yes, I agree with you on the fact that people who live on farms or ranches never bother to keep there dogs fenced in, some of the reasons being, to keep the coyotes away from the livestock, and to keep people away that shouldn't be there. Most of the time these kind of dogs don't leave the vacinity of the house or barn, for the most part, unless they are going somewhere with someone on the farm. That is the way it is with all the farms and ranches around here, as I have several friends who live out on them. I am in the Texas Panhandle for anyone who maybe wondering. I completely agree that what happened to your dog was totally uncalled for, and I would deffinately look into the laws on it, and it you really want to have some fun, give PITA a call, and tell them that the dog was allowed to run around totally free without fences and whatnot and tell them your story as I am sure they would give your local county pound a nice bit of trouble about it. No, I am not an advocate of the PETA in anyway or form, and personally think they are very dumb, but it could be a good laugh to give them a call.
