Jennifert, some people buy purebred dogs 'cause you get to know the general personality of that breed. Don't want to be cruel or bad or anything but in Chile we call the mutts kiltros and some of the are pretty ugly and here, any dog can get ticks! SO imagine a poor mutt in the street living out oof rubish and full of fleas and ticks that's why there are so many of them 'cause you'll have to spend a lot of money to make the dog, look, feel and act healthy. The real problem in here is that we don't have pounds so people just drop them on the street and that's where they stay. People from restaurants and shops and fishermen sometimes they give them some leftovers and stuff but most of them die of hunger.
