I think that dogs need to be dogs (and cats, cats) BUT on the subject of 'dog clothes' and hair ribbons and stuff like that, well we made them skinny with thin fur so of course we need to supplement that in winter (a woolly jumper) and we bred them with hair that grows all over their face, so it's only fair we tie it back so they can see out.
We wash them so often that we remove all the protective grease and oils from their coat, and cut their protective coats short, so they need some sort of weather protection in the rain ... and so on and so forth. Even the dog prams have legitimate purposes - if a dog who's always gone on regular walks becomes unable to do so, for reasons of normal ageing, and especially if the dog was used to being walked in company, then a pram will help the dog to still participate psychologically in the 'going for a walk' exercise.
It might also be necessary to help a dog on part of a walk if any problems might occur. I know someone whose dog has occasional, fairly mild and short, epileptic seizures, generally well-controlled by drugs. He's too large a dog to be carried for any distance so she takes him out wheeling a 2nd hand toddler pushchair. If he does have a seizure (I think he's had a couple in two years while out walking) she can wait it out, then when he's 'come to' she lifts him into the pushchair and home they go while he flops around held in place by his harness. Vet says it's much better for him to be out exercising and socialising and risk an occasional 'out of the home' seizure than keeping an active, intelligent dog cooped up, and this is the solution that works for them.
I had a darling cat who loved being dressed up and the local kids used to 'borrow' her to wrap in a shawl and a little hat, and push about in their dolly's prams! I would never have pushed her about in a pet pushchair though LOL!
