When it comes to a dog, there are so many things it can do that most of us have never even thought of. For instance, have you ever wondered if your dog can dream? What about sweating? I researched some of the most common questions and dug deeper to find a simple answer. 

Top 10 Strange Dog Questions Answered

1. Can a dog’s tongue change colors? 

Yes—if the tongue appears pale, this could be a sign of anemia or a weakened body. If the tongue is red, this could indicate hyperactivity throughout its system, and if a purple tinge is present, this might be a sign of pain or blockages somewhere in the dog’s body.  

Most of the time, a color change isn’t a good thing, so if you do notice your dog’s tongue changing colors, it’s best to talk to a vet as soon as possible.

2. Can a dog see colors?

Yes. But unlike humans, dogs only have one-tenth of the concentration in their eyes cones.

So when it comes to enjoying all colors, dogs can only see two colors: blue-violet and yellow plus any blend of the two. Outside of these two colors, dogs see the world in shades of gray.

3. Can a dog smell 100,000 times better than a human?

Yes; dogs can smell objects 100,000 times better than their human companions. Tests have shown that dogs can detect heavily diluted chemicals. The reason is due to their olfactory, which is 40% larger than a human’s and is for their sense of smell.

Along with the larger olfactory, dogs have 125 to 250 million receptors for smell.

Now you know why a bloodhound can track down hunted animals better than humans can!

4. Can a dog taste more than a cat?

Yes—dogs have a total of 1,700 taste buds as opposed to cat’s 470 taste buds. As one would expect, these are mainly attuned to the taste of meat and the fats and chemicals that are inside.

5. Can a dog sample scents by licking their nose?

Yes.  When a dog is sniffing around food, their nose can get pretty dirty. So because of this, they lick their nose to both clean the food and the mucus that is on it.

This allows dogs to lick off the scent chemicals so their olfactory glands can get a good sample of the taste.

6. Can a dog sweat?

Yes; Dogs do have sweat glands but are only seen in their paw pads. These glands are not dominantly used for sweating, though. A dog’s main source of cooling off is by panting.

7. Can a dog get a fever?

Yes, they certainly can! A good way to find out if your dog has a fever is if their nose is wet or dry. If dry, this is a good indicator of a fever. You will need to take their temperature rectally to be certain.

8. Can a dog predict the weather?

There has been some science that dogs have a strong sense of detecting storms and bad weather.

If you own a dog and have had bad weather, you may have noticed their behavior change before a storm. They begin to bark for no reason, or they hurriedly want to cuddle with you. 

This prediction often comes by smelling the rain before you do or even hearing thunder that you haven’t even heard yet.  Remember that a dog’s hearing is 20 times more sensitive than ours.

9. Can a dog see perfect at night?

One of many adaptations that dogs have is the ability to see in the dark.  The center of a dog’s retina has more light-sensitive cells, known as rods.  These rods work better in dim light, allowing them to see better at night than humans.

10. Do dogs dream?

Yes! Have you ever watched your dog while it was sleeping and noticed its legs twitching or they begin to whimper? This is an indicative sign of dreaming.  

Dogs dream just like humans do and it could be about similar things. We may never know, though, since we can’t dig deep into the brain to see what they see.
