There are now Amazon Dash buttons for Colgate, KY, Emergen-C and more

If you needed another reason to jump on Amazon's ultra-convenient Dash buttons, the online retail giant is giving you a whole lot more.

Today, Amazon added more than 50 new items to the instant ordering service, pushing the roster of different flavors to above the 250-item mark.

Brands now available for the service include Seventh Generation, Colgate, Emergen-C, Kingsford, Lifestyles and Rogaine. As always, the buttons cost $4.99, which is immediately returned to customers with the first order in the form of a $4.99 credit to their account.

And if you need still more reason to opt-in to Dash, Amazon teamed with dog food brand Iams to release this video celebrating the partnership, featuring a few Dash-certified good dogs.

Amazon Dash, which also enabled virtual ordering options last week, has seen its selection of brands grow impressively since its launch in 2015. There are now eight countries outside of the U.S. that support the buttons, and Amazon claims many of the partner brands receive over half their orders on the site through the buttons.

As Dash continues to expand, the Pavlovian shopping experience is sure to get even more into our heads. Just don't let your dog figure out how it works — you could wind up with a whole pile of extra Iams bags and a big mess of drool to clean up.
