Hi, I like to keep my Whippets on puppy food until they are at least a year. Could you ask your local shop to order a bag in for you. Failing that, all of the big pet places have puppy food. Don't forget if you change foods to do it gradually. Good luck with your puppy,
I don't know if it varies from breed to breed, but when I fed kibble I would change from puppy at about 6 months to Junior till 12 months before feeding adult?
