My 2-month-old puppy won't drink water. What can I do to help?

No need to apologize! Thank you for posting more information :-)
It's certainly interesting that he won't drink from the bowl of cool water or out of a training water bottle. As I'm sure you know, it's very important that your puppy drinks water for hydration and his health. It could be that he's drinking water when you aren't looking, and you can measure how much water you put in the bowl in the morning. The next morning, measure the water left so that you can see if he has been drinking water or not. He may not like the temperature of the water, as dogs can be more sensitive to temperatures than humans, so you can try to leave out room temperature water to see if he will drink that. He may not like the bowl, it could be too high for him to drink out of, so you can try a more shallow bowl. You could consider getting a water fountain for him. I have one of those for my dogs and cats, and they love it. Finally, you can mix in some wet puppy food with his dry food, which will get more moisture into his diet, or you can soak his dry food with warm water. If the methods I suggested above do not get him to drink water, or the water measurements you take show he isn't drinking water, then I would have him seen by a vet for a health check.
