Hi there ,
I'm doing a bit of research into presa canario dogs ,i met one a few months ago and that was it...

I want to start with the best bloodlines and have no expense spared so
i think (noobish) importing from spain or usa is best..?

My biggest worry is USA when i compare pictures on the web
a couple of USA presa websites have pictures of there dogs and they look like they have american pitbull in them,so my main question is...
Is it heard of for nasty breeders in usa to breed american pit's through
other dog breeds to get them in to europe...??

Thx in advance..
