Thanks to everyone who contributed to my questions on this thread about my collie: www.mumsnet.com/Talk/the_doghouse/4158443-Atypical-collie?pg=3
I thought you'd like to know that the results of DDog's DNA test are in, and he is NOT a purebred collie! Apparently he is 75% collie and 25% Australian Kelpie! So, a herding dog crossed with a herding dog.
It doesn't make much difference to how I'll be approaching things with him as he is obviously largely collie but with an added Antipodean slant. So if anyone has any experience/advice on Kelpies, do let me know. But I'm pleased we know, and the 25% explains his atypical longer legs and snout. I think black purebred collies are probably quite unusual, and his black bits are jet black with a russet tinge, which definitely looks more Kelpie. I like the idea of a crossbreed for health, too.
We've had a generally good week with him: I've been crating him for an hour or so every morning and evening to encourage him to switch off and relax. He's really good at wandering in to his crate so when he does I treat him then shut the door. And a couple of times in the day when he goes in I just treat him and let him wander out again.
This morning I had a really nice walk with him - we saw dogs from a distance and even at a distance that I thought he would react to and he didn't. So that was good. The reactivity in the car is still a real struggle, but small signs of improvement.
Any thoughts on his Kelpie heritage greatly appreciated!
