I own a doggy stroller because I LOVE TO GO Antiquing and to outdoor markets,farmer markets during the morning hours is ok for my Prada to walk around but once the summer sun comes out the asphalt gets really hot, I put her in the stroller and she is safe, cool and off the reach of sweaty little hands..
I only take one or two of them out at a time, only walking in my hood I take the 4 together..
hugs,
