Does a cockapoo like water

yes but some dogs aren't too keen on it. It depends on the dog but my dog is always drinking it and she loves it.

Dogs need water as part of their diet, like all living things. As long as there is water in their food (e.g., if they eat wet canned food), they may not need to drink as much from a water bowl. But if their food is dry kibble, then they must have plenty of fresh drinking water.
