He is half Basenji and Half Beagle

Hello all,

I have a 45 pound Basenji and he turns his nose up to Purina One kibble (both the lamb and the salmon (sensitive stomach formula).

On a whim a friend suggested I try Purina Puppy CHow and he likes it. Is he too old for Puppy chow? Is it bad for him? Ive heard that some dogs can eat puppy chow up until 2 years old.

Anyway, any suggestions are apprecaited. Thanks!
