I strongly second What a Great Dog! in Frisco. I did a couple private sessions with Maureen (the owner) before going into group classes with Meaghan (I'm only halfway through Pet Manners 1).
The private sessions were great for working on things specific to Red and getting one on one time (and I must say I LOVE Maureen!!), while the group classes are wonderful for working around other dogs and teaching me how to work better with my little man.
They offer SO many classes and have a wide variety of things to look forward to after Pet Manners - agility, barn hunt, rally, etc. Their pricing is very reasonable and it'll definitely be worth the drive!
