Fabulous pictures of Else, Mazy and Ludo, I especially like the black and whites, must work that one out on my camera. Maggie looks besotted with Elsa following her and looking at her.
Mandy, Ceilidh had her collar on from the day she was picked up as far as I remember and pretty sure it was on most of the time. I think it is more a case of leave it on him until he comes to terms with it. Sorry I am not much help.
Tessa, it sounds like you are on the right tracks with Evie, I am sure Ali and Christine will help as much a possible and it will all eventually click into place. Would love to see more pics of her...
