When is his birthday? He’s almost exactly the same age as my pup. He absolutely loves his agility classes as it has helped so much with training and creating a better bond/understanding between us. Even if you don’t ever compete, classes will still benefit you both. I do sympathize with the dilemma you face, I have a three year old intact Dobe/GSD and don’t plan on neutering him. I have no reason to. He is crazy athletic but doesn’t deal well with other dogs so competition isn’t really feasible with him anyway.
