Retrospec Rover Waggin’ Pet Bike Trailer – Small & Medium Sized Dogs Bicycle Carrier – Foldable Frame with 16 Inch Wheels – Non-Slip Floor & Internal Leash

I recently got this for an upcoming Road Trip we are planning and I wanted to test a month earlier with my dog just in case, a week and half later with daily rides, so far so good.PROS:-Fast shipping-Instructions to assemble aren’t great, but you can figure it in less than 5 mins.-Very simple and easy to assemble the Wheel Guards and both wheels- not much at all-Sturdy, nice size, lovely color so cars can see him- Easy and fast to hook and unhook from bike-it has a pouch in the back – nice feature- it has a leash holder hook inside- nice too- it has a plastic cover in case it rains – front mesh door-easy storage, it flattens for those who cannot storage in a garage- plenty of space and mesh for him to look around- sides, front and back.CONS:- found only one so far, my personal experience and opinion: zipper to open the mesh in front only closes at the bottom, so I cannot have my dog’s head ONLY out in the open, if I open the whole thing up because of the zipper situation, he thinks he can get out…training still going on. What I mean is that I cannot have half of it open if I wanted to, it opens all up and for dogs that are not used to this or cages it’s hard to get that they have to sit and just look.
