Never leave a puppy in his crate all day; he needs several bathroom breaks, as well as play and feeding times. Even though he won’t want to soil his sleeping area, if he is in there for extremely long stretches, he just might. (He can’t help it!) And if he does, it is because his owner has neglected his responsibility, not because the dog has misbehaved.
Discourage him from biting or nipping. Instead of scolding him, a great way to put off your mouthy canine is to pretend that you're in great pain when he's biting or nipping you. He'll be so surprised he's likely to stop immediately. If this doesn't work, try trading a chew toy for your hand or pant leg. The swap trick also works when he's into your favorite shoes. He'll prefer a toy or bone anyway. If all else fails, break up the biting behavior, and then just ignore him.
In competition obedience training, “heel” means the dog is walking on your left side with his head even with your knee while you hold the leash loosely. Puppy training can be a little more relaxed with the goal being that they walk politely on a loose leash without pulling. Some trainers prefer to say “let’s go” or “forward” instead of “heel” when they train this easy way of walking together.
Help him relax when he comes home. When your puppy gets home, give him a warm hot water bottle and put a ticking clock near his sleeping area. This imitates the heat and heartbeat of his litter mates and will soothe him in his new environment. This may be even more important for a new dog from a busy, loud shelter who's had a rough time early on. Whatever you can do to help him get comfortable in his new home will be good for both of you.
Choose a well-ventilated crate that is large enough for your puppy to stand up, lie down, and turn around. Remember that your puppy’s crate will have to grow as he does, so purchase a crate that is appropriate for your dog’s expected full-grown size, and use a divider to make the crate smaller for the time being. Many crates available at pet-supply stores include dividers.
Remember that training is an ongoing process. You will never be completely finished. It is important to keep working on obedience training throughout the life of your dog. People who learn a language at a young age but stop speaking that language may forget much of it as they grow older. The same goes for your dog: use it or lose it. Running through even the most basic tricks and commands will help them stay fresh in your dog's mind. Plus, it's a great way to spend time with your dog.
Born after an average of 63 days of gestation, puppies emerge in an amnion that is bitten off and eaten by the mother dog. Puppies begin to nurse almost immediately. If the litter exceeds six puppies, particularly if one or more are obvious runts, human intervention in hand-feeding the stronger puppies is necessary to ensure that the runts get proper nourishment and attention from the mother. As they reach one month of age, puppies are gradually weaned and begin to eat solid food. The mother may regurgitate partially digested food for the puppies or might let them eat some of her solid food. The mother usually refuses to nurse at this stage, though she might let them occasionally nurse for comfort.
