Henkelion Backpack Carrier/Bubble Carrying Bag for Small Medium Dogs Cats, Space Capsule Pet Carrier for Hiking, Travel, Airline Approved- Black Size: 12.2*11.4*16.5 inches (Please measure your pet first before purchase) The dog carrier backpack fit most small pets up to 10 lbs. Consider the length and weight of your pet comfort level in enclosed spaces I have 3 cats and I was able to use it for each one of them, one is 11 lbs, another is 12 lbs and the last one is 16 lbs. But its legit weight limit says 10 lbs. the base cushion has a small defect, the edges of the sewing kinda come out of the plastic in a small area, it does not affect functionallity at all.
