Q. My dog doesn't seem to be drinking, what should I do?
DANA KOCH, VMD, MLAS
A. If it has been this way for a long time and your dog seems otherwise healthy (eating, active), he/she may be getting water from other sources, such as wet food, outside, or the toilet. I would try to identify other sources they could be getting it from first. If the dog is truly not drinking or not getting moisture from wet food or other sources, he/she may need to be examined by a veterinarian.
It is more concerning if a dog suddenly stops drinking, especially if he/she also stops eating. This can be a starting sign of almost any illness and definitely warrants veterinary attention. If the dog is still drinking some, and still eating and active, there may be a less serious reason for the change. For instance, cooler temperatures, food changes, and decreased activity can cause decreased water intake.
