The 2023 price for Petco puppy classes is $179 for six classes. I purchased a 12-week package which covered both puppy classes as well as a private S.T.A.R. Puppy test; that package is currently $279. (Petco also frequently runs specials online; I had a 20% off online coupon for further savings.) They also offer an 18-week package of the two puppy classes, an adult class, a 45-minute private lesson and the S.T.A.R. Puppy test for $409. (Again, watch for coupon codes.)
