that's a very unkind comment. These dogs are likely old, injured or unable to walk for some reason.
When my dog had both his cruciate ligaments done (metal plates) he was on very restricted exercise till they healed. He had to be supported to pee/poo as couldn't put weight on his back legs at all.
He was only 2 at the time so found this most frustrating and boring.
I carried him to local park and put him down to pee, then picked him up again and took him to another spot to pee and so on.
I did this cos I love him and at least this way got to sniff the air and mark his territory. i suppose a bit like taking a disabled person out in a wheelchair (done that too). They still like to get out and about.
Quite frankly a dog 'pram' of some sort would have made it easier as despite being a small dog he is quite solid and heavy.
I doubt any dog owner would push a healthy dog in a pram for no reason. We know people are judging us.
My dog is getting old now and has heart problems. I've already thought about what I will do when he is no longer able to go for walks. I'll probably just drive him in the car to different parks and let him doddle about. However I might buy some sort of dog 'pram' so I can walk myself for exercise and let him enjoy some fresh air, dog sniffs, new territories.
Yes I will buy the least looking 'pram' one I can find cos I have no desire to have anyone think I am taking my dog out in a pram.
Very small minded/cruel though what you said.
Dogs are very loving, loyal and kind and ask very little from their humans. It's a shame that most of us are not worthy of them.
