I have two full blown Borders and a 1 year old Border crossed with a Long haired Jack Russell, all three are great dogs and are all different in there own way, the older two used to get worked but are now more like pets but still live outdoors and the pup is now my running partner and i can’t tire him out, he also loves to go swimming, but thats because i have had him doing it since about 7 months old, he loves it, but the other two don’t and won’t really go anywhere near the water, all in all i would say that as pet they are great dogs but like most they need attention and lots of good walks and time spent getting the dog you want, I.E swimming, running etc…
