How bout those wild dogs and other nuisance critters!
Our deer lease has one side that has a highway down one side of it, and it seems to be a place where people want to dump their unwanted pets out. People don't realize that a dog that has been turned loose becomes a predator/scavenger, and will pack with other dogs to create a REAL problem for everyone. We have to go in about every two or three years and shoot out a pack or two of animals, to keep them from killing small fawns, and calves from the ranches around the lease. I sure don't like doing it, but it is a shame to have to look at them half starved to death, with their ribs sticking out, and the breeds that don't shed, will be packed with hair that is matted so bad, that they can hardly see.
The animal rights guys, need to worry more about the people who are not responsible enough to have a pet, more than worrying about the hunters.
The hunters get stuck with the job of having to clean up for them, and we wind up taking the wrap.
I have been a pet owner since I was a kid, and I have had pets that I had to put down, but I took resonsibility on myself to take care of it myself, not just drop my problem off on someone else to do.
