This carrier is really cute and functional. The inside is very roomy....my puppy is only about 3 lbs and he has soooo much extra room in this. It would probably carry a 10-15 lb dog EASILY. I gave it 4 stars for durability because I haven't used it that much and because the viny isn't the highest quality, but for the price its great.Oveall....very happy with the product. Definitely recommend it.
