Hi guest, Dalmatians really like to have human company. I can't quite work out from your post if 3 hours is the longest it would be left in a day meaning someone would be with it for 21 hours. Or, do you mean it will be left for 3 hours, then you pop back for lunch, then it is left for several hours again?
If it is the former then this should not be a problem, it should soon adapt to this routine, I would recommend you took a bit of holiday to settle a pup into it. If it is the latter, then I am afraid this would be far too long to leave it, especially a puppy or a dog that is not used to it.
Hope this helps
