Tough Little Dogs

I always knew little dogs were tough, the chihuahua I had when I was a child would take on anybody. I just read where a chihuahua and a border terrier warded off an attach by a mountain lion. The big cat came into their yard and the two guys defended their territory. It pinned the border terrier but the chihuahua's barking convinced the mountain lion to release him and leave. Both dogs are fine. Those are two tough little dogs.
