I groom a few of these. Lovely but can be really barky at times. I think they're fab dogs, clever, but require a fair amount of grooming (sorry, had to get that in there!)
I've got two. They're great dogs, energetic when you want them to be. We do agility with ours. Both are curled up asleep on sofa now!! Yes they do take some grooming if you want to keep them fairly long coated, but if you keep on top of it its fine. Hope this helps. Lx
Grew up with one, and I loved him. He wasn't the best trained though (could very well have been us rather than him though), but was kind with children and other dogs.
I used to walk one and I really thought he was fantastic. A a typical independant terrier so it took him a while to think I was ok. But once he decided I was a "good guy" he was the most loving and fun dog to have out.
