Here's a video of sheep being moved from one pasture to another. The shepherd is the one that takes care of and leads them. The Shepherd often has dogs that help round up the sheep and guide them to where they need to go. The bible shows us that Jesus is the shepherd of His people, watching over, protecting and guiding them.
Then said Jesus unto them again, Verily, verily, I say unto you, I am the door of the sheep.  All that ever came before me are thieves and robbers: but the sheep did not hear them.  I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture.  The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly.  I am the good shepherd: the good shepherd giveth his life for the sheep.  But he that is an hireling, and not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and fleeth: and the wolf catcheth them, and scattereth the sheep.  The hireling fleeth, because he is an hireling, and careth not for the sheep.  I am the good shepherd, and know my sheep, and am known of mine.  As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep.
We saw this toad out in the evening and we're thankful he didn't get stepped on. God made so many different creatures, isn't that wonderful? Do you have frogs or toads around your house?
The Bible talks about how Pharoah held the Israelites captive and whould not let them go. God punished him by sending frogs to over run their land.
And the Lord spake unto Moses, Go unto Pharaoh, and say unto him, Thus saith the Lord, Let my people go, that they may serve me.  And if thou refuse to let them go, behold, I will smite all thy borders with frogs:  And the river shall bring forth frogs abundantly, which shall go up and come into thine house, and into thy bedchamber, and upon thy bed, and into the house of thy servants, and upon thy people, and into thine ovens, and into thy kneadingtroughs:  And the frogs shall come up both on thee, and upon thy people, and upon all thy servants.  And the Lord spake unto Moses, Say unto Aaron, Stretch forth thine hand with thy rod over the streams, over the rivers, and over the ponds, and cause frogs to come up upon the land of Egypt.  And Aaron stretched out his hand over the waters of Egypt; and the frogs came up, and covered the land of Egypt.  And the magicians did so with their enchantments, and brought up frogs upon the land of Egypt.  Then Pharaoh called for Moses and Aaron, and said, Intreat the Lord, that he may take away the frogs from me, and from my people; and I will let the people go, that they may do sacrifice unto the Lord.  And Moses said unto Pharaoh, Glory over me: when shall I intreat for thee, and for thy servants, and for thy people, to destroy the frogs from thee and thy houses, that they may remain in the river only?  And he said, To morrow. And he said, Be it according to thy word: that thou mayest know that there is none like unto the Lord our God.  And the frogs shall depart from thee, and from thy houses, and from thy servants, and from thy people; they shall remain in the river only.  And Moses and Aaron went out from Pharaoh: and Moses cried unto the Lord because of the frogs which he had brought against Pharaoh.  And the Lord did according to the word of Moses; and the frogs died out of the houses, out of the villages, and out of the fields.  And they gathered them together upon heaps: and the land stank.
