Fleury was a biter as a pup - had my hands bloody and raw - but I had expected as much. But once I tuckered him out he was great - and super easily trained. I had read up on crate and potty training, etc. He had his moments for sure, but nothing like the sass I'm getting from him now. I guess I read up on the puppy stage and knew what to expect but missed the literature on the teenage stage! Unfortunately, I think we were just building his stamina as a pup because now we can go on a long hike, he naps for a while and then begging to play fetch in the back yard. We have him in puppy agility now too which gets a good three hour nap afterwards, but that's only once a week...Haha thanks Jessac! I'm not sure if that makes me feel better or not I know what you mean, the good and lovely pups must turn into the craziest dogs. Coop practically trained himself as a young pup, he was that good and patient and don't get me wrong when he is good now he is great, but when he is bad... he is a little demon dog with the height and weight of a bull!
