Why do dogs pant?

Dogs pant to cool off when they are feeling hot.  When our body temperature gets too high, we sweat.  Evaporation of sweat from the skin takes up a lot of heat, and helps cool the body.  But dogs are almost completely covered with hair, and have every few sweat glands.

They can’t keep cool by sweating.  Instead, a dog pants.  It sticks out its tongue and breathes rapidly.  By panting, a dog moves air back and forth over the moist tissues of its mouth and tongue.  As the moisture evaporates, body heat is carried away, and the dog feels cooler.–Dick Rogers

Why do geese fly in a ‘V’ formation?

Geese are web-footed birds closely related to ducks and swans.

Wild geese sometimes fly in the familiar V shaped formation when moving to or from their breeding grounds in the Far North.

We can only guess why the geese fly in this formation.  One idea is that the geese follow a leading on their flights.

Because its eyes are located on the sides of its head it would be easier for a goose to see the other geese in this formation.

The goose at the front of the triangle is a wise old gander which knows the traditional route, with its various safe stopovers.

The term “silly goose” does not apply to these handsome birds.

Geese are cautious and very intelligent birds.

While on the ground, they seem to post sentinels to stand guard against danger while the flock feeds.

The Canada goose is probably the best-know goose of North America.  A large Canada gander may measure well over 3 feet, have a wingspan of over 6 feet and weigh up to 13 pounds. – Dick Rogers
