My mom bought this one to fly my brother's puppy out to him in arizona (it was a blue heeler and almost to big for it as a puppy (probably 10-15lbs). Mom gave it to us thinkin logan can use it always which I would imagine he can. Logan is 6 lbs. Anytime we get ready to go somewhere he jumps in it. We have a towell in the bottom and a toy in there. If we actually close him in he'll go right to sleep. If we leave the top open even a little bit he'll try to come out, but he's getting better about this.
