The last dog, is a collie x greyhound (3/8 5/8), and probably the best ferreting dog i have seen. She is eight.
The black dog is 100 % whippet (well, as 100% as any of the strong working whippets are), but i big, strong lad. He's two and a half and shaping into a good ferreting dog, although he works best 1:1, and is an excellent mooching dog.
The other two are a collie/whippet/grey (blueish brindle) and a line bred collie/grey x collie/grey (etc) (red brindle).
and can't forget the little dogs!
Russel type terrier, great for covering holes in thick cover etc.
