Having moved more than most I'd suspect, including both ways across the Atlantic, but not on my own (human) and certainly not without numerous hounds, I'd suggest your dogs will be absolutely fine provided you keep to their normal routine as much as possible. The first room we set up was their room, beds, water bowls and put a baby gate across the door so there was no possibility of moving people leaving doors open. And you do need to be aware of that. We also took our lot out locally for a good walk asap so they started to learn the neighbourhood and where their new home was in relation to the neighbourhood. Basically it all revolved around the hounds first. And us second.
Dogs usually move fine, and appear to quite enjoy exploring new surroundings. Much better than cats for sure.
Oh and do check the fencing in your new place, ahead of letting them outside. As for local walks, this is just something you'll have to hope you find (in terms of free running). Again we made sure suitable walking areas were available before moving - just as with vets!!
Good luck - I'm sure it will all go brilliantly. Enjoy.
As I didn't know where you are moving to, I Googled and found this ..........
