From this, it should be clear that dogs and cats (and countless other animals) don't walk around with four knees. They've only got two, and they're always in the rear. Now it does look like our pets have knees in the front, but those are actually wrist joints.

Do dogs have knees?
Dog leg anatomy is complex, especially dog knees, which are found on the hind legs. The technical term for a dog knee is the stifle joint. The stifle joint connects the femur, which is the dog thigh bone, to the tibia and fibula, the lower leg bones, and the patella,the canine equivalent to the knee cap.
What are animal knees called?
Digitigrades include walking birds (what many assume to be bird knees are actually ankles), cats, dogs, and many other mammals, but not plantigrades or unguligrades.
Do all walking animals have knees?
All four-legged mammals have 2 knees and 2 elbows.
That includes dogs, cats, elephants, horses – all quadruped animals. Their front legs bend exactly like our elbows.
What animals have 2 knees?
Ostriches are the only animals in the world to have a double-kneecap, but its purpose remains an evolutionary mystery.
What is a dog pastern?
The pastern is the area of the leg that is below the wrist (or carpus) on the front legs but above the foot. On the hind legs, the pastern is the area of leg below the heel (hock) but above the foot.
Do penguins have knees?
But yes, penguins do have knees! A penguin's leg is composed of a short femur, knee, tibia and fibula. The upper leg bones are not visible as they are covered in feathers giving penguins a very short legged appearance. Here you can compare the leg of a penguin skeleton (left) to a model of a human skeleton (right).
Do chickens have kneecaps?
Yes, chickens really do have knees. Jammed exactly between the chicken's drumstick and thigh is a joint for a skilled butcher to cleanly sever. Typically tossed in the garbage, these tiny knees have been transformed by the Cantonese into fried and fragrant nuggets of crunchy, chewy cartilage and tender bits of meat.
What animal is tiptoe?
There is a reason that many of the largest mammals, from rhinos and hippos to giraffes, walk on tiptoe. Starting to walk on their toes and hooves may have allowed these animals to become huge and take over the planet.
Do monkeys have knees?
Primates have a great range of motion in the knee. Therefore, unlike many other mammals, there is a significant part of their distal femoral surface that must contact the patella during flexion and the tibia in extension. ... The chimpanzee knee is clearly patellar dominant whereas the human knee is tibial dominant.
Is there an animal without knees?
But frogs live such different lifestyles to ostriches that they might not tell us anything. Bizarrely, many of the ostrich's closest relatives don't have kneecaps at all. In 2014 Regnault showed that emus and cassowaries, and likely the extinct moa, all seem to lack kneecaps.
What animals have 4 knees?
Elephants are the only animal to have four forward-facing knees. All other four-legged animals have at least one pair of legs with knees that face backwards. Hanging around the savannah is thirsty work and the average elephant drinks more than 200 litres of water per day. That's two very deep bath-fulls!
Do horses have knees?
Carpal Joint – The carpus (carpal joint) on a horse is commonly referred to as the “knee” which is only on the front legs. The tarsus is the corresponding joint on the hind leg, commonly called the “hock”.
Why can't Elephants Jump?
In the case of the elephant, in fact, it's impossible. Unlike most mammals, the bones in elephant legs are all pointed downwards, which means they don't have the "spring" required to push off the ground.
Why are ostrich knees backwards?
Yep. As with many non-humans, ostrich thighs aren't that long. The main joint we see when they run is the ankle, which is why it bends “backwards” when they flex it.
