polly - no 7 if you still need it - it's a breed, the chain anagram is in the middle, monicker is X ,sapper isn't an engineer, but an adjective here, this mean is "me"- i.e. the setter. If this sounds like rubbish, just look for a breed with chain anagram in the middle!
I still need 8 too.
Dhole it is the for that other one!
