## Customer Reviews

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    The bag needs to be reinforced
  

*by M***E on Reviewed in the United States on April 21, 2019*

The bag is great, but definitely not reinforced for 40lbsvas the description claimed. My 31lbs dog’s weight made the bottom fall apart. The last expansion area need to be reinforced. He did love it in there while it lasted. It almost functions like a thunder vest. He’s sung in there, happy to check out things around him.

### ⭐⭐ 2.0 out of 5 stars







  
  
    For dogs only up to 30lb maximum
  

*by A***R on Reviewed in the United States on December 21, 2018*

It’s written that it fits for the dogs up to 50lb, but my dog is medium size, only 36lb and he is too big for the backpack. But the quality of the backpack is ok.
