Thanks for the comments and useful suggestions!! We've had a really good weekend, and no accidents in the crate and he is really getting the hang of toileting outsite (although he HATES the rain and refuses to sit down if its too cold!!).
We have his final jabs on Friday so I am really looking forward to being able to take him for a walk in a few weeks so he can get rid of the huge amounts of energy he has! There is only so much chase and play we can have in a small yard! The ear licking has completed stopped too (but thanks for the suggestions anyway, I have printed them off for future reference). It was mainly the first few days where my other dog was obsessive about it.

On another issue, both my dogs play a lot of the time and really enjoy tug games and chasing, but sometimes it all gets a bit mean (from my older dog). I don't get involved as i'm sure they will sort themselves out and I have never felt it was bad enough to intervene. I assume this is ok!
