There is no reason at all at your dogs age he can't be in a kennel for 8 hours. So if between you and your hubbie you can get to him in about 8 hours he will be fine!! Please don't listen to people who tell you it isn't nice to kennel your dog. They are not people and will feel safer and more comfortable when alone if in a kennel. My Yorkie loves to burrow in to a blanket or squeeze under a chair to nap. If it is around bed time he just goes and sleeps in the kennel! So please don't feel guilty it really is the best thing for him!!!
I wouldn't give him any water while in the kennel.[ Not even an ice cube ] He will sleep most of the time so doesn't need it. If it is there he will drink it than have to be uncomfortable trying to hold it and will be more likely to get a UTI or have an accident. I know this goes against what feels right. But he is a fur baby and you have to think of him as one.
PS It will help to try to tire him out before you put him in the kennel too!
