My 14 week old pup hardly ever seems to drink. She goes for a wee offen and seems normall in every other why. Should I be worried about her not drinking water?

when you ring the vets about her being sick, tell them about her not drinking aswell. :)

Depends on what she is eating.  Tinned food is 75% water and raw food is full of moisture and so dogs will drink less than those fed dry foods.

She eats nature diet so I surpose thats pretty moist. She has never drank much its not something thats just started.

Well I would not worry about it then, naturediet must be 70 - 75% water?! :)

MY pup is also on Nature Diet and doesnt drink that much! So It must be usual for this to happen.
