Not such a stroll for me. I found this hard going and felt that (combined with the method of entering the down solutions) the across clues didn't allow the dog to see enough of the rabbit.
Cruncher, I hadn't heard of the "cut" flower at 11, but found the answer via TEA. As for 21, I had a perfectly acceptable solution to the definition and wordplay, but the "cut" element didn't fit the theme. Afraid I had to go to TEA for that one as well. Doh, I could have submitted a correct entry without knowing 21!!!!
Having said all that, i rather enjoyed it.
