whats with the smell

Layla had the weekend with my mum while we were away, and the text I got from mum day 2 was " Very sulky dog when I got home from work.  Went for walk to shops and she was great helping me in the garden"  A photo was sent to prove it.  I think my mother is as mad as me!  maybe that's where I got it from!!!!!

Anyway today when I took Layla for a walk- she was not so well behaved.  She found a dead eel in the reserve and OMG did she find it and suddenly she became deaf to the command of NO NO NO.  And again she sulked all day, after i washed her.  Whats with a sulking dog and a crazy owner that doesnt know a good smell when her dog finds it.
