Well just going off the dogs I glanced at to me they looked like UKC show dogs or more amstaff than game bred dogs ... Is this line supposed to be amstaff? Or would you consider it a show line? When I say big/large I don't mean big/large like american bully large I mean big as in not the average 30-55 lb game bred dog ...It depends on which you look at...LOL. That is why I used GARNER'S FOXI ROXI as an example. Just showing they all were not big.
Actually, I have not seen any full Castillo bred dogs showing in my area and thus I don't think that is what they are breeding for...In the past though they were shown.
