So, when our Miss Lily ruptured a disc, damaging her spinal cord, we had a dilemma!  How will she get around for an amount of distance? Bing an older lady, bad back myself, I started the search.  
None of the pet stores have any equipment for disabled pets!! Online I went.
Researched several options. We will be getting he "wheels" eventually. This stroller is GREAT!  I love the front wheels; easy turning in tight areas.  It is very well made. 
This will be wonderful when I go to my camper to run around visiting all my friends !!!
