The trend is simple enough to copy: photograph a dog doing something unmistakably summery, pair the image with a bright caption and post it before the weather changes.
What started as a handful of poolside clips quickly expanded into beach photos, backyard sprinklers, road trips and increasingly elaborate pet accessories.
Why it matters
The appeal comes from its low stakes. The format does not require a challenge, a dance or a complicated edit. It is just a stream of cheerful images arriving at exactly the moment people want one more weekend of summer.
Brands and larger pet accounts have begun joining in, but the most shared posts remain the casual ones that look like they were made for a family group chat first.
