Cooper is too heavy for my husband or I to carry him…I love the product thought! Going to have to put Cooper on a diet!

Love it!

I have a cavalier king charles spaniel and bought this for mainly travel so I can take her on flights with me as a carry-on but she is also 11 years old so it helps when she gets tired on hikes and stuff like that. I bought a medium but she's a bit of a chunky monkey so I could have gotten the large for a better fit lol she weighs about 30-35 lbs. The medium is just a little tight on her.

Great stuff!

Easy to use on the trail when the Bichon grew tired and he likes it.

Great for hikes!

I got this backpack for my small dog friend to take on longer hikes and hikes where I wanted to avoid ticks. It worked out really well! Cooper seemed to enjoy just hanging out in the pack and getting a higher view of everything. This backpack carried his weight well so I was able to carry him for long periods of time without getting sore. Definitely would recommend for pups who are trying to hang!

LOVE our pack!

Although it was a little small, my Diesel ended up loving his pack! He usually hates being in anything like this and did so well! Will definitely be ordering another one for my other boy!
