Our 12 weeker has been peeing probably 20-30 times a day. We think it's probably because when he goes on his wee pad, he gets a treat. Sometimes he'll keep leaving little dots of pee on the pad over and over again within a 20 minute time frame seemingly to just get a treat

. Sometimes he'll even squat on his pad, and nothing will come out, but he'll come running over for a treat

!!!!
But, we are concerned that there could be something else going on. How often should a puppy his age be peeing?
(Also he's 4 1/2 to 4 3/4 pounds, in case that matters...)
