Too Friendly

I have the sweetest one year old big bernedoodle boy who does wonderfully in most situations… I used to help with therapy dog training so he's followed that curriculum since day one and we've worked hard to socialize him with exposure to a variety of environments, people, and animals. we used to be able to take him anywhere with no issue. However, since about puberty, he gets overly excited when he sees other dogs – especially when out on a leash. He's desperate to play and it feels like his brain turns to fluff with all of our training out the window. He is also not always mindful of cues from other dogs while playing when they don't want to play – he just seems convinced everyone wants to be friends. We've tried a variety of techniques, but haven't been able to do much to curb it – and we'd love to be able to take him for walks and to breweries and to see friends again. Would relish any tips and advice 🙏🏼
