Loading Andy Cohen data from Instagram. Please wait... @bravoandy : I took the 28-day Challenge when I switched @theRealWacha to @PurinaONEdog years ago. Now that he is 7, we’re making the switch to Purina ONE Vibrant Maturity. For every person that signs up for the #28daychallenge, @PurinaONEDog will donate $1 to the PetFinder Foundation (up to $28,000) through 10/31/19. Click the link in my bio to register.
