Purchased back in 2021 when our dog was recovering from a neurological issue that affected her muscles and prevented her from being able to go on walks. It was very silly, but good to still be able to get out of the house! She’s fully in remission from her issues and back on her regular walking schedule so her stroller can now go to another dog in need. Connects to bike and acts as a bike trailer.
