my dog has that same problem when she goes for a ride in the car (she's covered in her drool in minutes), its most likely because hes nervous. if your dog gets nervous or insecure without you around, he may drool alot because his breed loves attention and get nervous/sad when their owner is doing something they cant get involved in. it proplebly means he loves you! :) but if it becomes too much of a habit, id contact your vet :)
