### ⭐⭐⭐ 







  
  
    OK for very short durations
  

*by F***4 on Reviewed in the United States 🇺🇸 on November 21, 2016*

As other reviewers have mentioned, the cooling pack isn't very big, especially for the small-sized harness pack, and it doesn't stay cold for more than an hour. We live part-time in South Texas and the cooling pack hasn't stayed cold for more than 30 minutes during 15 minute walks in 75 degree Fall weather. That's not hot by any means for Texas weather, so I don't anticipate that the cooling pack will stay cold for more than 15 minutes in normal, 85+ degree Summer heat. It's likely a better solution if you live in milder weather and/or only plan on taking your dog out for very short durations of time on hot days.

### ⭐⭐ 







  
  
    cooling vest
  

*by S***. on Reviewed in the United States 🇺🇸 on April 20, 2015*

the idea is great however it doesn't work in practice. the little vest doesn't keep my dog long enough to walk a block down the street. She's a Boston Terrier so she over heats quickly. perhaps it would be good to keep a dog warm but I haven't tried that as we live in SW Florida where it stays very very warm year round

### ⭐⭐⭐ 







  
  
    Smaller than I thought
  

*by C***C on Reviewed in the United States 🇺🇸 on August 1, 2014*

Didn't actually use it.  Had to send it back b/c the harness was too small for my dog.  But it was much smaller than I thought it would be.  I don't think it would last too long in 90+ degree heat.
