As an animal lover, but fearful of pit bulls, german shepherds and certain two legged mammals, it is interesting to note what other countries are actually implementing because of the concern over pitbull behavior. I was fortunate enough to have a very lovable English Springer Spaniel who played with every other dog in the local dog park - irrespective of the dog's DNA. Pitbulls, huskies, collies - all played together. My own dog's DNA tested 75% pure breed, but he was 100% the best dog ever. Everytime, I went to the dog park - whether in the early heat of a NJ summer or a late December snowstorn - there did not seem to be a hierarchy of who to play with based on "appearance". Every dog came to the gate and greeted him in the same manner, then they romped for a few minutes and then one or the other became bored and moved on to the next playmate. Having met other Spaniels - I did notice a certain lack of an attention span - but that only made him more loveable.
In the land down under, officials are now actually calling for DNA testing to confirm/deny that a dog is a pitbull or not? Really, what does it matter if he is pitbull or terrier - if he bites the hand that feeds him - he will bite anything. If the dog is a menace in the neighborhood to children and adults alike, what does it matter what's in the dog's DNA. Concern is over, visual identification of the dogs because some dog breeds - as in Staffordshire Terrier - although pitbull like in appearance are probably closer to Spaniel in temperment. How awful for a Staffordshire Terrier owner to have to worry about some "nosey" neighbor reporting his pitbull as a possible threat to the neighborhood. I've only met one Staffordshire Terrier - who is as beautiful and affectionate as any pup - but he is a powerful looking animal - broad chested - muscular and strong - a true Prince.
If you are concerned that your new best friend has any pitbull tendencies - then a quick, non invasive DNA test can determine if your dog has any "pitbull" DNA. Whether you have rescued the dog from your local animal shelter, or adopted from an animal rescue company, DNA testing can confirm the presence of over 50 breeds of dogs and offer advice on what health concerns and what behavioral issues are known to a specific breed. My spaniel had the biggest ears and the biggest ear infections - only briefly touched upon by the well intentioned animal rescue group - but his DNA test confirmed that he was in fact a Spaniel and was in fact prone to these issues. I probably could have figured that out on my own but the DNA test, confirmed it for me.
