My dog found a dog. I was with my dog at the time.

8. I also live in a high dump area..

With plenty of coyotes (and some very large raccoons). Had a big boy (feline) show up mid-December. The next week, we knew cold weather was coming. Attempt one to get him in the garage failed but attempt two did not. He'd been an inside cat, no doubt about it. He was NOT even a year old and of course, not neutered and not chipped (not that we'd have given him back). Absolutely NO ads for a lost cat fitting his description - kid and I scoured all the websites. He's now neutered, vaccinated, and spoiled. Thankful we have the financial means to do the neuter/vaccinating plus initial blood work (no feline leukemia or kitty aids).
So thank you very much for bringing her in and I feel your pain with the let go. We've had to trap a few "dumps" who we knew were probably all euthanized. All but one were not in good health (visual and behavior), not sure about the one. But yes, better than what would have likely happened. All but one of our fur-babies (canine and feline) were rescues/from the shelter.
I've NEVER understood the thinking of "well if I take to the local shelter, they'll euthanize". You think the animal ACTUALLY has a better chance on the streets/dumped out in the country?
Yes there is a special hell for those who mistreat animals. May they never cross my path.
