My two Dobermanns, Busta and Jagger, absolutely love WAG yoghurt drops.
It doesn't matter which flavour they will eat them for as long as you are prepared to keep feeding them. Having said that they particularly like the flavour of these ones.
If I rattle the jar they come running from wherever they are in the house or yard. Seriously - they know the sound of that jar rattling and they literally stop what they're doing and come straight away.
I don't feed them very often and because of that these are a very special treat that they look forward to.
