Stumped

The clues weren’t a problem but, try as she might, Millie just couldn’t get to grips with that pen.
This is one great dog! K&L think she’s part Bouvier, part Ridgeback. So by current fashion she’d be a Bouviack. Their other dog (Mr Watson) is as friendly as anything but pure, pedigree mutt. Went with K when he was walking them today and was amazed by the chilled-out Millie. Quite a contrast to the terrier part of Mr Watson!
Otherwise just chilled, had a swim, wandered up to the pharmacy with S to replenish cold-medicine (she’s suffering), enjoyed the evening at home with Sue and the Arnies.
