I have to add a couple of points to this topic as well.
1. a dog I believe can only be as good or as bad as the owner who is teaching them. For instance, one of my exboyfriends' brother -in -law had a big rottie chained in the backyard, he of course was the only one that could ever approach the dog (no one else dared to). It's favorite things were eating cats (disturbing thought) and chewing on the big black rubber ring on the bottom of traffic pylons. I approached the dog, reached out my hand and let him come to me and sniff me out (never showing fear of course, being the dog- lover that I am). Within a matter of minutes I was petting and playing with him. Before I knew it he layed down and rolled over so I could pet his tummy! The owner was upset replying that now he had go ahead and retrain him all over again b/c I turned him into a big pussycat!
2. the second thing about this is: one day I was flipping channels and came across "animal emergency" or something like that the show was called. Anyways, a little 12yr old Sheltie had been rushed into the emergency room b/c the owners were at the park w/it when a Golden Retriever had attacked the little Sheltie. I guess the Golden had picked up the Sheltie and shook it ripping the skin- fur and all, away from it's body. The fur had been ripped from one side starting from the stomach going up to the spine. The vets were trying to keep the Sheltie from going into shock, giving her IV antibiotics to keep from getting infection and trying to figure out how to sew her back together or even if she would survive. The skin was so torn around the stomach area that her stomach was actually falling out! It is a very disturbing story, but I just have to make a point about how aggressive and the damage that any dog, no matter the breed can bestow. The little Sheltie of course had to be put to sleep- very sad!:(
This topic always gets a rise out of me b/c I too have come across so many very sweet pitbulls and think it should not be the dogs who get punished but the owners. There needs to be stricker laws put on the bad owners out there. There also needs to be stricker laws enforced on people who torture animals (animal cruelty laws).
