Thanks everyone!
Ennierda - I am in a quandary! I love her coat and think it looks fab the longer it gets, BUT I know it won't be long until her adult coat makes it difficult to groom, and she already seems to get pretty hot in the hot weather (and it's been beautiful weather here, but not exactly a heatwave), and when she is old enough (only a couple of months away) I plan on having her run with me and I think she might expire if she wears a fur coat while jogging!
Plus, I do love seeing 'Lo and Kendal's girls all nicely trimmed, I just worry that Rosie won't look like Rosie if I get her trimmed! I think I'll wait another couple of months and then do it. Maybe keep her short in the warm months and shaggy the rest of the year.
Kendal - it's funny, I always think she has a reddish hue, especially in the sunshine, although she was very definitely chocolate when we got her. My daughter is flame haired (and it gleams in the sunshine) and I think Rosie is copying her!
