How Many Times Should a Dog Bite Before He is Euthanized?

The no-kill movement has spread through the United States like wildfire. U can relate to the no kill movement, I am an active advocate in saving the lives of animals. Some of whom wouldn't have had a chance without someone with serious disregard to being bitten by an animal. I have had my share of dog bites, I have had my share of cat scratches. Why do I do it? Because I feel all animals deserve a chance. However, I am here to ask you, how many chances do you believe that a dog or cat deserve?

A dog or cat that doesn't have a history of attacking is great. They are easy to love and easy to relate to. However, I have serious doubt that many people in the no-kill movement would enjoy fostering, or adopting a dog that has a history of biting. I have done just that, adopted a dog that has a history of violent behavior. His behavior was so bad, animal control wanted to euthanize him. I don't believe that I would have even had a chance to save his life if it had not been for my status as a foster. However, his story ends great. He has calmed down, and he has developed a great sense of family. Many of these dogs do not change over time, they do not stop biting. If given a chance at a stranger, chances are that my dog would bite someone, which is why I do not put him in a public setting. I took the risk because my dog is small. He is a patterdale terrier, and weighs maybe about 15 pounds. 

Would I take a large dog that has a tendency of biting? Chances are, even though I am an animal advocate, I would pass on the chance. This is simply because of the amount of damage that a larger dog could inflict if he did bite.

Even with this information, and the fact that not a single one of the animal advocates I know would take a large dog with a history of biting, there are petitions flying around the internet begging for pardons for large dogs that have a questionable history of biting. We even have one going around my area. 

A large pit bull bit a 14 year old community service worker. This particular instance could have been prevented by the 14 year old. He was in a restricted area when the bite occurred. An area that he was told explicitly not to go into. However, because of this animal's history of biting and intimidating attitude, even active no kill advocates are not wanting this dog to be pardoned. Why? Because he is violent and has a long history of biting, even in the animal shelter. When people who work day and night to save any and every animal they can do not think this dog should be adopted out, or even held in the animal shelter, there is a serious issue with this dog. 

Yes, people are signing this petition, mostly because they do not know the entire story. Now I turn the comments over to you. How many chances do you feel a dog should get before animal control calls it quits?

How many times should a dog be allowed to bite before they are euthanized?
