All animals that use their limbs for locomotion have knee joints on their hind legs, just the same as humans. Creatures without legs would also have no knees.
Some of these include:
Snakes
Invertebrates
Fish
Marine Mammals
When watching 4 footed animals it often appears that they have no knees, this is because to run fast the knee has migrated up to the top of the leg so appears to be a hip (it remains in the same place on the front limbs
Unfortunately, you cannot physically make your knees smaller as they are a joint in your body. Your knee size is determined by bone structure and genetics. If you are concerned about the appearance of your knees, you can try exercises to tone the surrounding muscles or speak to a medical professional for guidance.
Joints make it possible for your knees and ankles to work.
When someone says their knees are like jelly, they are describing a feeling of weakness or instability in their knees, often due to fear, shock, or extreme nervousness. It implies that their knees feel wobbly and unreliable, as if they might give out.

No. Actually, the elephant is the only animal with four knees.
A giraffe is a savanna animal with padded, hairy, and callused knees. Their knees are padded with thick skin and hair to protect them as they frequently kneel down to drink water or graze on vegetation.
Having knees...
Ostriches have two knees on each leg, which some people refer to as four knees. However, anatomically speaking, these joints are not all knees.
Giraffes have padded and callused knees to support their long necks when bending down to drink water or graze on vegetation in the savanna.
2. A previous answer here said four, however only elephants have four knees. A rhino's legs rotate like a dog or cats, so they only have 2 knees.
It means that you get down on your hands and knees, and stand like a four legged animal, 'on all fours'.
Most mammals (e.g. horses and dogs) have knees that bend the way human knees do. However, when you look at a mammal's leg, the knee is not in the same place you're used to finding it. Many four-legged animals actually walk on their toes, and have elongated feet and ankle bones. Take a look at a dog or horse skeleton on the internet, and you can see that what seems to be a "backward bending knee" is actually the animal's ankle!
I don`t know... my Grandpa??? NO really it`s a wild bore.
Yes, giraffes do have knees.
This concept is referred to as a misconception, because animals do not have backward knees. The part you think is a backward knee is equivalent (homologous) to your ankle. Notice that your ankle bends "backward." Animals have forward bending knees, just like you, but they are often overlooked. Look higher up on the animal and you will see their homologous knee. In some animals, there is a lot of muscle and/or loose skin over the area, so it looks like a rounded hunch near their hips.Stand up. Lean over. Bend your knees a bit. Now stretch your t-shirt down over your knees. This is how you might imagine many animals having 'hidden' knees.
