12 Fun Facts about Dogs

Fun Interesting Facts You May Not Know About Dogs

With dogs being domesticated animals, we often view them as part of our families with similar traits as humans. However, these four legged furry friends boast a number of different abilities and characteristics that make them a very unique type of species. Dogs used to be wild animals, and their history and biology sets them apart from us in many small ways, providing them with different strengths and abilities humans are incapable of. Here are several fun and interesting facts about dogs you may not already know.

  1. Dog’s nose prints are unique like fingerprints. Just like with human fingerprints, a dog’s nose has its own unique pattern and can be used as a form of identification.
  2. Dog noses are wet because it allows them to smell better. The moisture helps absorb scent chemicals to then enable them to understand and identify what the smell is.

3. All dogs dream but young and old dogs dream more than adult dogs. There is not enough studies done to determine exactly what dogs dream about. However, research shows that when sleeping, dogs do revisit activities and events that happened while they were awake. 


4. Yawning is contagious for dogs; even the sound of a human yawn, especially if their owner yawns, can trigger dogs to yawn. They don’t necessarily yawn because they are tired or have a buildup of CO2, but dogs yawn typically when feeling anxious or to empathize with those around them when they yawn.


5. When sleeping, dogs curl up to protect their organs. This is most likely carried over from back when dogs were mostly in the wild, and needed to protect vital organs and keep warm when sleeping. 

6. Surprisingly, dogs are not colorblind, but can actually see blue and yellow. They see the world in various combinations of blue and yellow, rather than black and white. 


7. After relieving themselves, dogs kick backwards not intentionally to cover it up, but rather to mark their territory using the scent glands in their feet. Additionally, it is believed that dogs spin around before going to the bathroom to align themselves with the Earth’s magnetic field, preferring to align with the north-south axis. 

8. While cheetahs can run really fast, and can sustain an average speed of 70mph for 30 seconds, a Greyhound can beat a cheetah in a long distance race. Greyhounds can run at a speed of 35mph for as long as 7 miles. It’s all about endurance over speed.


9. Dogs have three eyelids, rather than just two. The third eyelid is called the nictitating membrane, and it helps protect the eye and keep it lubricated. The third eyelid is off to the side along the snout. 


10. A bloodhound’s sense of smell is so accurate, their tracking can be used as evidence in a court of law. Bloodhounds have the ability to follow tracks that are over 300 hours old, and can stay on the trail for up to 130 miles.

11. Dogs have 18 muscles in their ears compared to humans with only 6. This enables them to be able to move their ears in many directions, and pick up different sounds with each ear.


12. When calculating the equivalent of a dog’s age in human years, the popular belief that one year of a dog’s life is equal to seven human years is actually inaccurate. Depending on the size and breed of your dog, each year as your dog grows older they reach different milestones. After the first year, dogs grow close to full adult maturity physically, but mentally they may not have reached it. Larger dogs typically mature and age faster than smaller dogs. 

These are just several interesting nuggets of information about dogs not commonly known. As with most species other than humans, there is still so much we do not know. Although we may not know everything about things such as specifics on how dogs’ brains actually function cognitively or how they can have the ability to be so in tune with the world around us, that does not mean they deserve any less respect simply for their differing abilities. Needless to say, taking steps to understanding dogs and their various strengths and weaknesses (or rather different abilities) can allow us to better learn how to care for them.

The Importance of Supporting Small Rescues Rescue work is like a dam; if it doesn't keep flowing, it all stops. In a time of historically high shelter overcrowding, the heartbreaking reality is that dogs are being killed in exchange for space to accommodate the constant intake of more dogs. It's a vicious cycle that we rescues strive to interrupt. The most efficient way for rescues to save dogs is to utilize a foster based approach, and for the community to get involved. Without fosters, we are either forced to place the dog in a boarding facility or to leave the dog's life hanging in the balance at the shelter. Though the dogs placed in boarding have technically been “saved,” the rescued dog is still in a shelter like environment while the search for a foster or adopter continues. Often times, the public and networkers often forget about them since they aren't at risk of immediate death. Boarding for long periods of time can negatively impact their stress levels and they may exhibit signs of anxiety or depression. For some dogs, it can mean regression or behavioral changes. Not only does this put additional stress on the dog, but places financial stress and responsibility onto the already overworked rescue. While rescues certainly appreciate the shared passion from fellow advocates who pledge and plead for the safety of dogs in the shelter, rescues NEED FOSTER FAMILIES!!! Foster care greatly improves the chances of a dog being adopted. It is imperative for their rescue. We urge you to help the dogs in your community. If you have the ability to foster, do it. Even just a week of fostering can be the catalyst for a beautiful future. When the community comes together to support the flow of animal rescue, we will see greater life saving outcomes.

If you have considered rehoming your dog, it is critical to do so humanely and responsibly. When dog owners advertise their pups as being "free to a good home," they may have the best of intentions. In reality, it can put the dog in a dangerous situation. Listing any animal on Craigslist, Facebook, or other websites and forms of social media as “free to a good home” may put the animal at risk of falling into the wrong hands. With shelters overcrowding and dogs being turned away, people often resort to this method of rehoming out of desperation or blissful ignorance. Many may not grasp the potential harm and it is crucial for pet parents to understand the risks of posting for pets for “free”. Criminals scour the internet in hopes of finding these listings, knowing they can easily prey on these families and their pets. They will rely on that raw emotion and make every effort to persuade you that they will make a good guardian to the pet. Naturally, people want to believe others are good and would never harm an animal, which is to criminals' advantage. In many unfortunate instances, the dog may end up involved in dogfighting, unethical breeding, resold commercially, or to a laboratory. Some laboratories try to save money by recruiting dishonest middlemen who deal in stolen animals. These sellers are referred to as "Class B dealers" and are recognized by the USDA as random source animal sellers who are permitted to sell animals to research facilities for use in experiments. Animals are often obtained by Class B dealers in dishonest ways. Your animal will become unprofitable to them if you charge a little adoption fee, so they'll probably look elsewhere. Those searching for animals to abuse typically won’t pay an adoption fee. By having an adoption fee and a screening process, you can also stop people from impulsively adopting your animals, returning them to the shelter when they lose interest, or leaving them otherwise neglected or abandoned. Dogs require expenses past being adopted, so an adoption fee can also guarantee that the person is willing to pay these expenses and are more likely to take them to the vet and supply their needs. An adoption fee is just one way to ensure the new pet parent is willing to make an investment in the animal. Preforming a home visit, asking for personal and vet references, checking animal abuse registries, and forming a contract are just some of the important ways of making sure that your dog is going to a good home. If you are unsure of how to rehome your dog in a proper way, consider reaching out to your local shelters or rescues for help to ensure their safety. If a dog owner truly cares about the life and well-being of the dog being re-homed, taking the steps above to ensure he goes to a good home are worth the time and effort.

With shelters filling up quickly, rescue dogs all over are facing euthanasia at faster rates than ever before. South Carolina specifically, has an overflow of rescue dogs. Everyday more dogs are coming in than are being adopted or fostered, putting shelters in a state of emergency. With the population of humans increasing, and the growth and development of areas like Charleston County, there naturally will be a surge in dogs, but it is common that lack of responsibility that is one of the main reasons hundreds of dogs are being surrendered on a daily basis. A shortage of veterinarians is also a contribution to the overcrowding, as South Carolina has a law that adopted dogs must be fixed, and 75% of the shelters don’t have a dedicated veterinarian. Due to the lack of space and large population of dogs, it is becoming more difficult for shelters to establish a calm and comfortable environment for them. The shelter is already often a scary place for dogs, so with adding pop-up kennels and additional dogs, comes new stress and fear for dogs. This may also affect how quickly they become adopted as people commonly avoid reactive dogs, but it is hard for many dogs to remain calm in this situation. If you are unable to adopt, shelters ask for you to please consider fostering as it will open space in shelters to maintain a positive environment and bring comfort to the dogs you choose to foster. Medical bills are also a major issue for shelters and animal rescues as many dogs come in with injuries or sick and face costly care. Viruses like distemper are spread easier and are more common because of the overcrowding. Due to many of these places being ran on volunteers and donations, these costs are extremely hard to cover making donations crucial. Sharing this crisis on social media and helping to spread the word is also vital in getting these dogs the second chance they deserve.
