I bought a stroller from e-bay all in all, the total was $47.00. It is a 3-wheeler and folds down pretty compact and very easilt!!
I have put Trini, Coco, Gracie and their 2 pups in there and they all cuddled snugly while we went for a walk. But I wouls say it is good for 3 Yorkies max. I love it! It is pink and black and has a small hook for a lead/harness... The seller was petsweetie. I also got it in 2 days from when I paid for it.
PM me if you want more info.
