Im interested in taking my dog to obedience training at Petsmart. If anyone has taken the classes Id like some feedback….. was it worth the money? did it seem like they were training your dog hands on? did the trainer personally helped with issues, or did he/she just basically read out of a book out loud to everyone? how did the trainer interact with each student? did it feel like a personal session or di it seem overcrowded and hard to keep up? thanks in advance.
