Just like all mammals, dogs need a male and female to make puppies.

Girls dogs can have puppies from 6 months old

Girl dogs can have two litters of puppies
every year.
Click on the puppy to see what that looks like…

What are Mites?
• Mites are like little animals, like little ticks, but much smaller.
• Scabies mites can cause scabies.
![Page 9: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/9.jpg)
This is a mite
She is very small.

.
She is very small. Let’s use a magnifying glass to make her bigger.
This is a mite.

.
This is a mite.
We can just see her! Let’s look closer under a microscope.

How does Mange spread in Dogs?
![Page 16: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/16.jpg)
Mites can cause mange in dogs, and make people itchy too.
![Page 17: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/17.jpg)
Mange miteSarcoptes
The eggs hatch, and more mites come out.
This life cycle takes about 1
month.
The baby mites grow up into adult mites.
Adult miteslay eggs
![Page 18: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/18.jpg)
Mites live in the skin.
They make a dog itchy so they loose their hair.
![Page 19: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/19.jpg)
Mites make tunnels, crawling around under the skin.
![Page 20: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/20.jpg)
How does
mange spread in dogs?
Mange crawl using their legs…
![Page 21: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/21.jpg)
Mange mites can walk from one dog to another
![Page 22: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/22.jpg)
One dog spreads mange to others Treating some dogs doesn’t stop the problem The drug wears offs and the mites crawl back on
![Page 23: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/23.jpg)
The mange medicine kills
the mites but doesn’t kill the eggs
![Page 24: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/24.jpg)
The mange medicine kills
the mites but doesn’t kill the eggs
![Page 25: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/25.jpg)
The eggs will hatch making more mites
![Page 26: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/26.jpg)
So we need to get rid of
the eggs before they hatch
Or use the mange medicine again
![Page 27: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/27.jpg)
How can we
get rid of eggs?
![Page 28: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/28.jpg)
We can get rid of eggs by cleaning out our
houses and washing all the blankets
![Page 29: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/29.jpg)
Mites also don’t like the sun, so getting lots of sunlight on things like mattresses will help
control them
![Page 30: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/30.jpg)

This is Mr Germ
He is very, very small.
![Page 33: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/33.jpg)

This is Mr Germ
He’s still too small to see! We’ll need a microscope.
![Page 35: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/35.jpg)
This is Mr Germ under a microscope.How is he moving?
![Page 36: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/36.jpg)
Let’s look closer.
![Page 37: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/37.jpg)
He has little legs called cilia.
![Page 38: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/38.jpg)
His tiny legs move him tiny distances.
![Page 39: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/39.jpg)
Oh! What is he doing?
![Page 40: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/40.jpg)
Mr Germ split in two.
![Page 41: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/41.jpg)
Mr Germ reproduced himself.

Germs can reproduce very quickly.
![Page 43: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/43.jpg)

Let’s make a graph to see how fast
germs reproduce.
On the bottom we measure how much time has gone by.
On the side we can measure how many germs we have.

Let’s find out…Like this?Then like this?Or maybe like this?Let’s find out…
That would mean there are less germs
as time goes on.

First get a big ball of plasticine to represent Mr Germ.
Plasticine isn’t alive, so it won’t grow,
but it splits just the same way.

• Germs are healthiest are strongest when all their needs are met. Germs need:
– Food– Water– Shelter– Warmth– Company
![Page 53: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/53.jpg)
• When warm, juicy food like hamburgers are left out of the fridge, germs from our hands, from the air and from flies grow very quickly on them.
![Page 54: Living and non-living things](https://reader036.fdocuments.in/reader036/viewer/2022062314/56813c67550346895da5f654/html5/thumbnails/54.jpg)
• Some germs are good for us, but too many germs can make us sick.
• Understanding how quickly germs, mites and dogs grow helps us to make decisions to stay healthy.
