They have to learn to eat only the things that are good for them. Sometimes a puppy will gnaw on a cake of soap, but he does not do it more than once, for he finds out it makes him ill. And dogs have to learn to come when their master calls them, and to lie down when they are told, and to shake “hands,” and do other tricks—especially in a circus.

So Mrs. Gurr showed Don, and his brothers and sisters, how to sniff and smell along the ground, so they would know their way back again when they had gone away from home. Dogs, you know, have very good noses for smell. Even on a dark night, when a dog cannot see, he can tell, just by sniffing the air, whether his master is coming along, or whether it is some one else.

So, when a dog takes a new road his paws leave sort of a smell in the dust. This smell stays there for some time, and when the dog wants to get back, he just sniffs and smells along the road until he finds where he has made his tracks before, and in that way he gets home again. He can do that even in the dark.
