When should you start training your dog? Mine puppy is 15 weeks German Shorthair Pointer and has learned 2 tricks, but would it be easier (and the best time) to teach them when they are older? I taught my 14 year old Black Lab how to sit and bark for her treats, and she got it down in 5 minutes and that was the only training she needed. My puppy took a week to learn to sit and shake, so is the factor on why he takes so long to learn is because he is a puppy? Will he be able to learn faster when he gets a bit older and not so crazy and wild?
