There are methods for hastening your puppy's transition from puppy coat to full-grown coat. If you want to get the process started, grooming is the way to go. But first, you'll want to get your puppy used to sitting through a nice brushing. Starting your dog with a grooming brush may scare them away from brushing in the future. So, if you're starting them early, you should first train them with a soft-bristled brush. In terms of grooming, this isn't going to help much. However, it will help them become accustomed to the sensation of brushing, allowing them to begin being properly groomed sooner.
