Apparently the dog had been seen by local families in the area; they were leaving food out for her. They know if there are traps around...and her injuries are pretty obvious...go take a look at the Facebook page in the link for a nice close-up. She likely tried to get the trap open, but ended up pulling her foot out of it, since there is nothing left but bones; her tongue and mouth were ulcerated from attempting to lick a frozen steel trap.
Thankfully, she ended up finding help from someone who decided not to joyfully put a bullet in her head.
Nothing joyfully about putting a bullet in her head just common sense.
I so glad that their are people out or are so willing to beg other people for money that they can spend it these stray dogs and cats.
We have no shortage of domestic dogs or cats.
Instead of putting the bullet in the dogs head, perhaps it should have been put into the person/persons who dumped the dog out in the first place. I have NO sympathy for such people and have seen that practice done more than once in our rural area. If someone chooses to be rid of such animals, do NOT dump them off but instead take them to a shelter (I assume shelters charge for such services and to avoid paying a few bucks, the “dumping” is cheaper. those type people are ba$tards!)
