Fact or Myth?
We call the dog man’s best friend, but how much do we really know about these four-legged companions? We take a look at some interesting truths and common misconceptions:
1) Dogs are colour blind, and cannot see colours at all.
Strictly speaking, dogs are not totally colour blind as they can identify colours, although not as well as humans do. Dogs can see certain colours such as yellow, blue and grey. Primitively, dogs are nocturnal animals and have to hunt for prey in the dark. Hence, their vision was made for the primary purpose of being able to hunt in the dark instead of identifying colours.
2) Dogs can cause asthma.
Asthma is a genetically inherited condition, which explains that dogs do not cause asthma. However, triggers to asthma include dog hair and saliva, even though these triggers may not be major.
3) Dogs can spread diseases to humans.
It is possible for dogs to spread diseases to humans, although cases of such are known to be rare and can be prevented with proper care and hygiene. Common infections include the hookworm. Fortunately, most viruses that affect dogs remain “species-specific” and thus have no effect on humans.
4) Dogs can eat whatever humans eat, so they don’t need to depend on commercially-available dog food.
A rule of thumb to follow when ensuring that your dog is well-nourished is that your dog needs specific nutrients rather than specific foods. It is possible to avoid commercial dog food and prepare fresh meals for their dogs. Some owners may find this more beneficial for their pet, although it tends to be more costly. Different dogs have different nutritional needs, so it is important that you know what combination of nutritional quantities are best for your pet. The diet should consist of a good balance of proteins, fat, minerals, vitamin and water.
5) Dogs’ teeth need to be flossed regularly.
Unlike human teeth, dog teeth are not structured to grind food. Instead, they are built to tear and cut foods like meat. Therefore, unless food is found stuck in a dog’s teeth and can’t be loosened out, there is no need for flossing.
