This is a great size for my 5 lbs miniature toy poodle. He loves jumping into the carrier whenever we're about to leave the house. I put in a large cushion for him to make it a little more comfortable. I love that I can wheel him around if my hands are too full to carry the carrier. There is a pouch on each side of the carrier, which is great, I use one to store his treats, and the other for his water bottle. Very happy with this purchase and I would recommend to others.
