My dog was unbearable as a puppy, hyper, super charged but it was all fixed by time outs and training, now for the most part he is pretty good (2 years 4 months) except when he plays the in and out, in and out... Now that its starting to thaw out its muddy and I have a trail in and out of the house. Wife looked at me and I said, its spring, the yard will dry up by june.
