dog training

We got my newest dog last year, right before quarantine hit (great timing). He was in puppy classes two weeks before they got cancelled. He's been a great dog since then and catches onto things very quickly. But recently there's been problems we cant seem to correct on our own. We've tried so many different things, and nothing seems to be working. Theres a really popular class near me but I've heard questionable things about them. If you've ever taken your dog to classes, I'd love to know your thoughts!
