My lab is pretty good alone but in the company of other dogs she gets super aroused and races out for a retrieve and then often prances around with the dummy getting more and more excited. I am practising for Grade 2 and the exercise where you walk her out and place a dummy leave and walk back to the 30 yard marker is problematic. Fine on the lead but otherwise she runs back for it then off! Distant retrieves and from a walk up are much better - it’s the close ones and throwing dummies around her that send her over the top. So much so that she actually starts shaking and won’t accept a treat. This tells me her head has gone! I’m going to try the “hold/carry/deliver that Pippa suggested when around other dogs. Anyone have any other ideas? Thanks.
