Annie is in her 3 week right now of her Petco classes.. She is 16 months. So it is never too late
The basic class is meant for older doggies
Right now we are working on the basics... But I am hoping in the coming weeks we work on other issues like barking at strangers (from the house at the street, etc)
It was only $89 for 8 weeks with a PALS card so not bad
