I have a 10 year old rescued greyhound who has always been a very sensitive soul. He used to have separation anxiety many years ago which we worked on and then we got another greyhound who we lost a couple of months ago. Since then our dog has reverted back to weeing sometimes when we leave him. He can have just been out for a walk or in the garden but still does it. He is also quite often getting up at 4 in the morning wanting a wee. He has always had a ritual of going out for a wee before eating and during eating so I have to make sure his food is not left when we are not there. He has never liked change. The thing is we are going on holiday next month and he is going to stay with my sister (where he usually goes) but I am worried he will not be clean in her house. She has said she will put him in the kitchen when she goes out which will be easy to clean but I'm wondering if a crate would help. I've never used one before though I've had rescued greys for twenty odd years. I don't know whether he would be too old for one now and if it would help. Any advice would be appreciated.
