That night, I researched frantically.
Page after page confirmed what Dr. Kim said. Dogs overheat from internal blood temperature, not external air temperature.
But traditional cooling products only treated symptoms after overheating began.
I read about military working dogs who could operate safely in extreme heat using specialized cooling technology that targeted blood vessels in the neck area.
But this technology had never made it to family pets.
Then I found discussions about something called the PetzyMart CoolLoop in dog owner forums.
Post after post from owners describing exactly what I was going through:
"My dog was getting depressed from constant activity restrictions. The CoolLoop changed everything."
"Finally found something that lets my dog be a dog again, even in summer."
"No more heartbreaking 'no' answers. My dog can play safely now."
One testimonial stopped me cold:
"The CoolLoop saved my relationship with my dog. I was becoming the mean mom who never let him have fun. Now we play fetch in 85-degree weather with complete confidence."
