Training is constant. When you can not be paying attention to a dog place them in their crate. Unless the dog is already trained. Remember a well trained dog is easier to live with than one which hasn't had any instructions. A dog is like a child, it has to be given instructions before it can learn a thing.
Training takes time and patience.
But the investment is worth it in the end. Tips on buying a dog Always have a contract saying that you the buyer can bring the dog back to the breeder within 3 or 4 working days in case your veterinarian finds health problems. If your veterinarian is the same as the breeders get a second opinion from a veterinarian who has no connection with the breeder. Because experience has taught me that some vets see the breeders as more of an asset than the mere pet owner. I feel every dog owner should own the following books.
