* If a dog were to completely refuse water and ingest no fluids at all, this could be fatal in as little as 3 days.
* If a Pug is drinking a bit of water but not as much as he needs, this can eventually lead to severe dehydration and corresponding organ failure in as little as a week (this will vary depending on the puppy or dog’s activity level, how hot it is out, etc.).
* Drinking much more than normal may be due to being excessively hot and since this breed can have trouble breathing in hot, humid temperatures, steps should be taken to cool the dog down (stop activity, bring him into the shade or a cool house, place cool wet towels on his body, etc.). However, increased thirst that does not relate to the weather or activity and occurs for more than 3 days in a row is your sign that a vet visit for a complete examination is needed.
