When did people start dressing up their dogs?

So when did Fifi start wearing a dress and Fido get his sports jersey?

What decade did the fad of putting clothes on your dog start? I’m not talking jackets/coats that keep the animal warm, I’m talking frivolous stuff like some of the stuff on this site.

It all started in 1959.

That sounds like something from the 1850s not the 1950s!:eek:
