Why Is My Pet Drinking So Much Water? Signs of Illness vs. Summer Thirst

As Tucson temperatures soar, it’s no surprise your furry companion is heading to the water bowl more often. Just like humans, pets feel the effects of the desert heat. Dehydration can become a serious issue in the summertime, making it essential for dogs and cats to stay hydrated. However, when your pet’s water intake seems excessive—even for a hot day—it might be more than just thirst from the summer sun.
At Adobe Veterinary Center, we understand that noticing changes in your pet’s behavior can be stressful. That’s why we’re here to help you understand what’s normal, what’s not, and when to schedule a check-up.

Summer Heat & Hydration: What’s Normal?

During summer, pets pant more, play in the sun longer, and lose water through both activity and heat regulation. It’s normal for them to drink more during this time of year. However, there are a few questions to ask yourself:

– Is your pet drinking constantly throughout the day?

– Are they urinating more frequently or having accidents indoors?

– Do you have to refill their water bowl more than usual—even after accounting for the heat?

Mild increases in thirst can be attributed to hot weather, but dramatic or sudden spikes in water consumption may point to underlying health issues.

When Is Excessive Thirst a Red Flag?

Two common health concerns that cause excessive thirst (polydipsia) and urination (polyuria) in pets are diabetes mellitus and kidney disease.

Diabetes in Pets: Signs to Watch For

 

Diabetes occurs when your pet’s body can’t regulate blood sugar properly. Besides excessive thirst, other signs include:

 

– Increased urination
– Sudden weight loss despite normal or increased appetite
– Lethargy or decreased energy
– Cloudy eyes (especially in dogs)
– Urinary tract infections

 

Diabetes is more common in middle-aged and senior pets, overweight pets, and certain breeds (like Dachshunds, Poodles, and Burmese cats).

Kidney Disease: A Gradual but Serious Threat

 

Chronic kidney disease (CKD) can develop slowly and often goes unnoticed until advanced. Early signs include:

 

– Drinking and peeing more than usual
– Bad breath with a chemical or ammonia-like smell
– Nausea or vomiting
– Decreased appetite
– Weight loss
– Poor coat condition

 

Kidney disease can affect pets of any age but is most commonly diagnosed in older cats and dogs.
