Input: I returned this because it was too small for my berry leggy dog. I thought it would be nice to be able to expand the case during layovers but she's still too tall and needs a larger case. When zipped closed the pet carrier feels sturdy. I don't know how durable the mesh is when expanded. Only complaint is that when closed the expandable mesh takes up some of the space inside. Best for smaller breeds.
