[quote]Just classify them as multipurpose working dogs and be done with it, ya know? Good post, btw. Missed it on the first glance-over.[/quote] Thanks, and I agree, I think putting them into one hat is sort of short changing them. I do think catchwork will tell you a lot about a dog, and I think its an important aspect of the breed. As for the op's reply to me, that he's already got a bulldog and doesn't need to see any more. I think you're wrong there fella. If you got out some more and saw some more dogs, you'd have already known that neither a "johnson" or a "scott" dog is inherently better at being a pp dog. What you're asking is a loaded question...do you mean actual pp work, as in a fully proofed dog that walks around with you everywhere under real threat, or do you mean a dog to walk your property's fence at night, or a dog to take out to the training field? "Protection work" is a broad term, and the american bulldog is a broad breed. I stick by what I said originally...get out and see some dogs if you want an answer to your question that you can see with your own two eyes. The best potential protection dog is not one type or another, its an individual dog with the traits your looking for.
