Hi, We received Yorkie's wheels last Friday. I am very please at how well it is made and how perfectly proportioned it is for him. It seems that he felt a little uneasy at first in it but later that day when he saw my nephew, he took off after him running at full force. I was nervous at first but the cart cornered well and for the first time in a month, our puppy (he's three years old) seemed to be his old self again; running and having fun. He still gets stuck cutting his corners to tight around a door frame but he's getting the hang of it. I am hopeful that he may walk again one day but for now he has his cart. I attached a photo so you can see our little cutie. Thank you so much.
