Hi Sara, I haven't been on here for a while, being as our boys r roughly the same age I did laugh when I saw your post, Brodie is exactly the same right now, he can get really stroppy too when he gets put on the naughty step (so to speak). He has learned (all by himself) to backchat to the word NO which has been making my new found dog walking friends chuckle when out walking him. His recall is non existent when there are other dogs about which is giving me cause for concern and we are working on improving it.
