I think I'm asking the impossible here but our lovely Labrador is almost 5 months old and has been attending puppy classes for the last 7 weeks. He's always been one of the more "excitable" puppies in class but last session he hardly stopped barking. I know it's stupid but it's quite embarrassing. I have to give him kongs, chews etc the whole time and then take them away so he can do the skill. He's very good at the actual skills but I know he's distracting everyone else there. He's such a chilled pup at home but he just wants to play with all the other pups! Anyone got any tips at all please? I was going to do another 4 week course when this one finished but think I might hold off until he's a bit calmer or maybe do gun dog or agility instead in the summer?
