My chihuahua loves his pine green pet stroller.  He is getting older and will only walk a little ways and then wants to be picked up and carried.  I let him walk until he tires, then put him in the stroller to complete my walk.  I put an additional pad into the bottom of stroller for extra softness.  The mesh is strong and makes him feel secure when other dogs are around like my granddaughters' collie.  Great purchase!
