There is obviously a reason that they are illegal in so many states. Now, I totally agree that there are other high risk breeds, but they come from long lines of domesticated animals and are not a handful of generations away from a wild animal. But I truly believe that crossing an animal that gets fed canned food nightly with an animal that takes down his meals by going straight for the neck results in an increased risk of aggression. I've come into contact with countless pitbulls, rotties, g. shepards, and many other breeds that tend to be labeled as high risk breeds; and I can tell you that the 3 hybrids that I've come into contact with were by and far the most intimidating. They look at you completely different than other dogs, big surprise, they're half wild animal. Now am I saying that these animals should not be treated.. OF COURSE NOT! They deserve to live long and healthy life just as any dog does, it's not their fault. I'm just saying that I feel that there is an increased danger (Maybe I'm alone on this one); and am wondering what the convention is when they are brought into a clinic. P.S. This may come off as confrontational, but that's not intentional.
