Border Collies also make great service dogs. If you have never seen a working BC herd..you will love this short flick! The ability to work in teams is amazing and fun to watch.Border collies are actually a very good example of you can't tell how well bred a dog is just by looking at them. :0
Have seen some performance line ones who have roached backs and other things going on. Awful looking dogs.
The show ones are breathtaking - and not just in the show ring.
Couple years ago, I got to SEE one in obedience whose dog got like a 199 score and beat out the goldens. Show line BC. Breathtaking dog. Moved like a dream. I remember the judge could not take his eyes off the girlie - primarily because 99.9999999% of BC's you see in obedience are the ones who are built weird.
Another example of a good vs bad breeder - the good breeders will make the earth move with their wrath if they find out that their dogs ended up in a shelter or rescue.
TBH, I believe that mine was either a farm dog that was surrendered for chasing livestock, or maybe a service type animal that the owner was unable to care for.
I also have the Golden Puppy (another farm dog), a BC/Lab mix puppy (farm dog too), and a Mini Aussie from an accidental litter west of town in the stix of Nevada. I would NEVER consider one dog better then the next..just different. The BC was my heart dog and is just..well..different and hard to explain.
