My boys are a little like that. They will not drink during our walk or for most of an outing (I carry a water bottle). They wait until we return to the car. Max will not drink much until we get home.
I believe the reason is they instinctively know not to load their stomachs with water when they are active. They shouldn't guzzle or drink a bunch of water during or immediately after physical exertion, especially in the heat. It's best to take a few sips and ease into drinking as they cool off. The water shouldn't be super cold either.
I think it is partially a bloat issue, which isn't as much of a risk in smaller dogs, but can be deadly in larger dogs.
There are other health reasons that I do not remember specifically. Same thing applies to humans, not drinking too much water in the middle of a marathon or other heavy physical activity.
