An update on Max, I have now let him off the lead and he has great recall. Its fantastic to see him getting the excercise that he really needs. He is really relaxed and very happy. I have started to crate train him, he is sleeping in the crate while I write this. I have not closed the door yet, its a great little space for him to hang out in. I think he likes it. Yes the cat has also had a good snoop and I will not be surprised to find her in it one of these days. Thanks to emma for giving me a loan of this crate.
