The average person moves every five years or so. This can put a lot of stress on your dog. The Herald Press has an article that could help:
Dogs are most comfortable with consistency and routine. As you're packing the house and belongings start to disappear, your dog's stress begins. When packing dog's supplies, leave out a few of his favorite toys so he has familiar things close by.If possible, take your dog to the new home a few times before moving day. This gives him the opportunity to explore his surroundings before the chaos of moving in. Once moved, get the dog's bed and toys unpacked first so he has familiar things in an unfamiliar place. Giving him a good chew bone or stuffed Kong will relax him.
A housetrained dog, in a familiar home, doesn't mean he'll automatically know when and where to go in a new home. Practice remedial housetraining for the first few days. Take the dog outside every hour or two, praising and treating him as soon as he eliminates. Confine to one room or a kennel if you must leave him alone gradually giving him access to the rest of the house.
