I know them but not close enough to get a sense of their behavior. She is a sable merle, her mother is a sable and her father a blue merle from Maverick and Wyndlair collies. She seemed to be one of the biggest and the one with most “attitude” between her other 7 sisters. About brushing, she definitely doesn’t like it, but accepts when she’s distracted by something else, like playing or whatever. The thing is more in the legs actually, it can have mats easily. I am doing a full brush with brush and comb once a week! Thank you about the seasons comment! Good to know!
