I do admit that I checked into a stroller when my 11-year-old dog was dying. She enjoyed her walks so much and being out in the fresh air. These were the things that gave her the little quality of life she was enjoying. The stupid strollers were just too damn expensive given her medical NEEDS. I walked her as far as she could walk, then carried her home in my arms. I treasure that time. We sat out on the back deck to enjoy fresh air. So in my case, it would have been for an old, sick dog. But I didn't get the stroller and would have only been able to use it for a couple of weeks if I had gotten it. I live in an area where it does get quite hot. We don't walk on the pavement during the hottest part of the summer. We take our walks for exercise. Legit: I don't take my dog to really large dog events. She is well-behaved, but so many other dogs aren't. Her last time around several dogs was agility class training a couple of months ago (taking a break due to the heat). I was around many, many dogs two weekends ago at an agility event that I attended at a spectator (my dog isn't ready for competition). It was helpful because I watched the trainers and saw many things I am doing wrong. First dog in agility so we are both learning. And agreeing with many, many others--your children are gorgeous.
