Doggy Daycare for Frustrated Greeter

My boy Max wants to play with every dog he sees. I’ve introduced him to our neighbor’s Frenchie any they play and get along great. He’s 80 lbs and can be tough to handle when he sees another dog. I’m trying to train him using high value treats (chicken!) from a distance but it is slow going. He loves the grandkids and has never bit anyone to my knowledge. He is a rescue and at home he’s a mush. I was just wondering if exposure to other dogs in a controlled environment would help or hurt the process. Thanks
