Lawrence some people will not like the answer to this but its just my opinion.
i first started working with hybrids because i could not get pure stuff , they were border x and black stuff x they worked well but some to hard for my likeing, don't get me wrong there is time and the place for a hard dog its just i don't see the point in haveing a dog that is laid up fo a week or two and can't be used ,as my dogs work with me to make a living. The coats on the hybrids are realy good tight and waterproof, but size was at times a problem there was always litter wastage especially in the border x
