#13 Labradors have such a good reputation that some owners don’t think they need training.

That's a big mistake. Without training, a wild Lab puppy will quickly grow into a very large, rowdy dog. Luckily, Labradors take to the training very well - often even outperforming in obedience competitions.
#14 You need to be extra careful when raising a Labrador puppy.

Do not let your Lab puppy run and play on very hard surfaces, such as pavement, until they are about two years old and their joints are fully developed. Normal grass play is appropriate, as is puppy agility, with its one-inch jumps.
