Can dogs swim?

Humans often learn to swim in formal swimming lessons. To stay afloat in water, very little action is needed; the human body is slightly less dense than the water. Human swimming involves the use of all four limbs in a unique way to how they are used during walking. Those with lower body fat, and a high center of gravity, have a tougher time staying afloat. The most efficient swimming techniques involve submerging the nose and mouth in water, posing challenges for swimming and breathing simultaneously. People generally cannot swim comfortably without experience or practice, and have on many occasions drowned, often due to panic. Children generally do not swim independently until 4 years of age. Drowning is the 2nd leading cause of death among Canadian children 1-4 years old.
