This is an incredible dog carting tote for Max I would suggest 15lb dog or smaller. I purchased for my mini schnauzer and I won’t use anymore as he will walk and doesn’t need carried. This bag is barely used, and I never did use the insert so it is brand new. It cost me 336 plus shipping so total $360! originally not to mention waiting forever as they are from Ukraine. I cannot beleive the quality of this bag and you won’t either, which is why I am not going to sell it for low ball price.
