I know people who have had success with the Petsmart training. We didn't do so well. The cages with the furry creatures were too close to the area they have set up for the training. Belly couldn't concentrate. He was an 11 month old BASSET ...and he wanted those hamsters and such. I had a lot of trouble keeping him on task. These things were literally 15 feet away.
I'm sure they have a good program but we decided to look elsewhere.
petSmart and Petco hire outside trainers. It can be rather hit or miss some are ggod some arn't. It is a good idea to watch a class to observe the instructor and how he/she interacts with the humans and the dogs along with the methods used. Will you and your dog be comfortable in that setting. Art the techniques taugh something you can use/do.
The other thing is you must also decide if you want an obedience class that is an introduction to fromal competive obedience or a "manners class"
here is a link on the distinctions keep in mind in the link "behavior training" is what I refer to as a manners class Dog Training
I agree with Mikey also. I took Sadie to puppy classes there. The trainer we had was VERY full of himself and didn't like Bassets! I stuck it out though, and learned what I could. He was knowledgeable, just a jerk.
We took our dog stella to Petsmart and it helped with her socialization alot. She was a rescue from a shelter and we needed all the help we could get. We still go back to visit and the trainer remembers her, and gives her treats.
Personally i wasn't thrilled with Petsmart classes, although Winnie enjoyed them. Found a training center that wasn't too much more expensive...paid by the class...could attend as many as you wanted(needed)...had a variety of times...has a big play area for the dogs before/after class
