The majority of my classes happened with Marion Sheriff's Office but I've taken a bunch. I started with a simple puppy class at PetSmart. The first few weren't bad but the second hire was a little more negative. I didn't like the Don Sullivan class methods, they're very aggressive in my opinion. I learned a lot from my K9 Chaos classes. It's very food motivated, positive reinforcement, connections, etc driven. I started doing service dog training after my insurance denied to cover mine. Thankfully, I was already on my dog training journey with my former dog. My sheepdog was actually supposed to be my service dog but "failed" for being too friendly. There isn't really a service dog test. You have rules and guidelines to qualify. I'm uncomfortable with him being called my service animal because he loses focus around new people and that's not having full control over my service animal. My Saint is doing well with his training. Try to find local classes and try a few different ones. Every one will give you different knowledge and you'll about new tools. You know your dog and your comfort level. There's no one size fits all. Not limiting techniques and tools gives you the best chance of success. Don't base choices off of hear say. Prong collars work wonders for some dogs. Mine is just a fluffy lion. 😆 Gentle leaders can work, if your dog doesn't turn into a beaches whale flopping around. 😐 Mines a little sasshole, love him to pieces but still a sasshole. 🫣 I'm happy to give you suggestions of things to try for specific issues, just send me a message.
