Hi, we have a very lively border collie, I think that it is the dog that has kept me going through the whole process. As Tom said don't get overwhelmed by cleaning everything, just be sensible, I carry on just as I used to with dog, just wash my hands after stroking him, like me he's very confused by everything. I've gone back to walking him everyday across our local fields,good for me and he loves it!
Still sleeping in separate rooms simply because I get quite restless, sleep well but move about a lot.
Try not to stress too much, I'm sure it will all be fine.
Regards Tony F
