Armani doesnt like treats either, only 2 kinds. Chicken Zekes treats and puperroni. My dad just bought him a huge bag (2lbs) I believe for $12 of pupperoni at Sams club. He gets this as a treat during the day (he only eats twice a day) so this basically helps me to know that he has something in his stomach between dinner and breakfast. HE really likes them especially right from the fridge cuz they are cold
he runs around with it, hides it gets it back out and then devours it
good luck. and you can get the zekes treats at Petco, they are a really good size for yorkies.
