Hi. I researched and purchased a Walky Dog Plus bike attachment so my dog could trot alongside me as I rode. The construction and the application are great. Just not for Jet. She's a little fearful. If you have a dog that loves to ride alongside your bike this is a great. It bolts easily under your seat and keeps your dog a secure and safe distance from your bike so you can bike anywhere with your dog. I paid $49.95 a week ago and I'm asking $25.00. I would have posted a photo but cant figure out how so you can google Walky Dog Plus for specifications. I live in Watersound and will let you try before you buy. Its a great tool. I would love to sell it to someone that can use it.
