I feel the same way towards animals, but honestly, if the dog is a stray, then the animal control cant do anything really . Now if the animal is owned by them, they you can call the ASPCA and fine his ass...
I try to live peacefully with animals, but it doesn't always work out. Doesn't help that half of 'em around here are dangerous, destructive or disease-ridden...
Good on you for looking after the dog though. My Mum's pet dog, and cats, were all rescued from various situations. I also remember taking a long detour whilst on a road trip with friends a while back, to get an injured Kookaburra to the vet. Yup, got plenty of adventure stories involving helping animals in need.
