That's a great link to the pattern site, thankyou. I didn't know Simplicity did so many dog patterns!
And I'd no idea that Next sold dog coats either.
It's definately the same knitting book we've got. I was given another two as well that are good. One's a Hamlyn one using mostly Rowan yarns, so they're easy to get, & the other one is American by Judith L. Swartz. If I get round to knitting all of them I'll have to buy her a wardrobe!
Is the Au Naturel you got them from the interiors & fancy goods shop, Juliealfiesmum? There's a small branch of theirs on an out of town shopping site not too much of a drive from me.
