Hayes Grier holds new puppy Zan up on his shoulders in their new peta2 ad.

The 15-year-old Vine star appears in the organization’s new “Adopt Don’t Shop” advertisement.

“Find Your Special Someone: Adopt, Don’t Shop. Never Buy Animals From Pet Stores or Breeders,” the ad boasts.

“Right now, millions of dogs and cats are waiting for the right family to come along and give them a home,” Hayes shared. “My friends at peta2 and I want everyone to know that helping homeless animals is as easy as visiting your local animal shelter and always being sure to spay and neuter, too.”
