I think “Pink is the new Red!” is a great branding hook. Here I’ve incorporated all the important info within a circle logo lock-up (Pink is the new Red!/Pinkerton Red Labs logo/website address, and Fox Red Labrador Retrievers)
Here the “Pink is the new Red!” and website address is enough to get the prospective puppy owner to go to the website.
Here we could post how many days old the puppies are, OR, how many days until you can see/pick your new pup.
And here we just have the generic, Pink is the new Red! catch phrase “hook”.
