This is true, that they arent totally secure. But in reality neither are crates. I can send you all my pins with their crates, and you will be amazed at how fast they can get out of them. My springer was the same way, would unlatch crates from the inside or outside.
Walking a healthy, fit, able dog is what you are supposed to do. Even an elderly dog needs a walk. But when circumstances arise that this is just not possible for a dog to do the walk that the breed is meant to do, then you need to accomidate that situation. If its using a pushchair, so be it. Joy was worked every day until she was around 13 years of age. She popped her shoulder out, and so walking became very difficult. Like, to go round my complex takes maybe 5 minutes. She couldnt do that. She could barely get to the bus stop (which at the time, was only 9 townhouse units) before she had to rest. It was sad to see her like that, but if I had a stroller, she could have gone out more, and at least smelt the air, gotten out.
After thinking on this thread to, I can see the use of them at shows. I really can. You bring in your large trollies, filled high with things, and they take more room going up the aisles than a stroller. It also has its safety reasons too. I dont know what shows are like in the UK, but here they are a mad house. Handlers and dogs rushing to ringside, not looking where they are going. Im sorry, but if a 150 lb person, and then their dog that weighs that as well, is running down the aisles paying no regard to whats around them, it could be hazardous to other dogs. I got a dog that is 11 inches. The other people arent paying attention to the floor, they are making a mad dash to the rings. She could get hurt. Is that fair to her? I mean it can get so mad in the grooming area and at ringside, that you need to actually carry your toy dog to and from.
There are benefits to the strollers, but when people use them for cutesy reasons, then thats a little much.
