Why I said:
The big questions are: Does the dog walk upright without any prompting? Is the dog able to balance without that basket? How many other dogs has that dog been around consistently? Does it have only humans to mimic?
And honestly, there are a lot of breeds that I'd put clothes on myself. Barkly has a little pleather jacket with a Harley hat. He's also got a Christmas Elf costume with a little tophat. I just don't have a lot of clothes for him b/c it's hard to fit dwarf-dogs, and I hate altering clothes for anyone--dog OR human.
Vlad doesn't have any clothes b/c I can't find any his size, but he has a Santa beard, hat and glasses. I've still got Dannyboy's Furby costume that he wore at Halloween though. I've got Dannyboy's pleather jacket and hat. I've got a bazillion bandannas for them. My determination about putting clothing on dogs is, do they fight it or run away?
These are put on dogs all the time so that people can take them backpacking with them:
https://www.backcountryedge.com/ruff-wear-approach-pack-2013.html How are we to know that the dog with the basket wasn't in a all-4-down position when it first started carrying that basket and actually is doing a job? We don't absolutely know that the dog is doing what it is because of training because more and more dogs perform as if they're human in many instances.
Seriously. What makes Vlad jump up and dance with me? Dancing around the house is common for me. He just stood up one day and joined in, and I'm not going to do something to break him from having fun when he smiles like that.
