Dogs aren’t color blind and other surprising myths…
our companion animals. Cats always land on their
feet. A dry nose means a dog is sick. But where do
these ideas come from and how true are they?
1. Dogs are color blind
The origin of this date is unknown, but the truth is in dogs do see in color. They just see a more limited spectrum that we do.
This is because they have more rod cells on their retina compared to humans, which allows them to see in much dimmer light; however, it also means they see more shades of gray then we do. Most dogs see in shades of gray, yellow and blue.
2-cats always on their feet.
Cats do instinctively try to fall feet first, but this isn’t always the case. They have a uniquely flexible skeleton,
which allows them to twist their bodies in mid-air to correct their position; however, a cat needs ample time to right itself and if she is surprised, sick or injured, she may not be able to do so despite the height. Furthermore, if
a cat fell from too high, it would not matter if she landed feet first, as the impact would injure her anyway. And no, attaching toast butter side up to a cat will not result in anti-gravity… although that would be an awesome cat trick.
3-if a dogs nose is warm and dry, it means it is sick. This is one of the “best” myths and most widely known. despite its bad temper, the warm, dry nose makes the dog warm and dry. It has nothing to do with the disease.
4-if a dog is wagging its, it is happy.
We hear this one at the shelter all too often. While most dogs wag their tails when they are happy, tail wagging it really a sign of arousal or attention. Much like a human smile, a wagging tail can mean a variety of emotions – tense, anxious, submissive, annoyed, frightened, aggressive, excited. Also, a fun fact – research has shown dogs tend to not wag their tails when they are alone.
5-cats have nine lives we wish they did, but obviously, this isn’t true. This myth likely originated from the fact that cats are very resilient and hearty animals with strong survival skills.
6- A dogs mouth is cleaner than a human's mouth
Dog saliva was once believed to be an antiseptic and many still believe it has healing properties; however, modern doctors would not recommend a dog-slobber bath. Dog Saliva can be toxic to some bacteria, but a dog’s mouth does have its own assortment of bacteria and infectious organisms – it’s just different than the population of organisms found in a human mouth.
7-One "dog year" equals seven "human years".
Contrary to popular opinion, there is no precise formula for measuring dog capacity develops in “human years.” Differences exist between small and giant breed dogs, as large bodies require more energy and larger dogs typically have shorter life spans.
8-You can't teach an old dog new tricks.
Now, this is just silly. You can certainly teach an old dog new tricks, old tricks, red tricks, blue tricks. As long as a dog is bright, alert, healthy and responsive, age does not limit his learning ability.
9-Cats purr because they are happy. This is similar to the tail wagging myth for dogs. Most cats do purr when they are happy, but it’s important to know they also purr when they are sick, stressed,
injured, frightened or in pain. It is important to pay attention to a cat’s body language when determining why a cat may be purring. If the cat’s pupils are large, she is breathing heavily and her ears are flattened, she may be purring out of fear
or stress. Yes and no.
10-Cats can see in the dark.
Cats can see in very dim environments because, like dogs, they have more rods than cone cells on their retinas. Rods operate well in minimal light,
register vision in shades of gray, and are very sensitive to movement. If you think about it, rods are very helpful for a talented predator like the cat! However, rods still need some light in order to work so cats cannot see in complete darkness.
