DNA test's for determining what breed of dog you own are NOT accurate don't even waste your money on that garbage.
And why are you at risk of having your dog taken from you if it's an APBT?
They became illegal here in the UK before I got him when a pitbull killed a child, that is why they sent out a guy to keep checking up on him, he came out to see his temperment and measured him but after 6 months of random call outs he said we were find to keep him, however recently they are looking to bring in a strong ban on "dangerous dogs" which would include staffies.
Everyone here assumes they are evil dogs, but my dog is everything but evil, he would probably lick you to death if that was possible.
He is actually my life, I have trained him so hard from playing dead to getting socks out of my drawer.
But it doesn't matter how good the dog is if its a pitbull it's taken from you and put down.
