WEDNESDAY WISDOM:
Ten Interesting Facts About Puppies
As most of you have probably seen, we have a new litter of Coton de Tulear puppies. They turn one week old today. Having a litter of puppies is a lot of work. I haven't gotten a lot of sleep in the last week and today I have been up since 3:00 AM with a crying puppy. But it's very rewarding to raise a litter of puppies and well worth the work.
Most people can't resist wanting to snuggle with a cute puppy. But beyond their adorableness, there are many fascinating tidbits to learn about these amazing furry friends. Let's dive into some facts that you may not be aware of.
1) Puppies are blind and deaf at birth. And there's a good reason for this - dogs are typically pregnant for only about two months. This shorter gestation period is a result of evolution; in the wild, a pregnant dog could not catch fast prey and contribute to the pack. Therefore, as dogs evolved, the less time they spent pregnant—the faster they could get back to hunting, according to Psychology Today. Pups don't open their eyes and ears until about two weeks of age.
2) Puppies have baby teeth. Like many newborn mammals, puppies are born completely toothless. At 2 to 4 weeks of age, a puppy's 28 baby teeth will start to come in. Around 12 to 16 weeks old, those baby teeth fall out, and by the time pups are 6 months old, they should be sporting a set of 42 adult teeth.
3) Puppies spend most of the day snoozing. Which is great for their moms and the breeders! They sleep up to 15 to 20 hours in a day. The American Kennel Club strongly advises dog owners to resist the urge to disturb napping puppies, because sleep is critical for a young canine's developing brain, muscles, and immune system.
4) When sleeping, puppies typically shake or twitch. Puppies' nervous systems are still developing, and these movements help build muscle and form the connections necessary for motor coordination. And just like humans, dogs dream, and these dreams can manifest as twitching and movements during sleep. Sometimes they look like popcorn popping when they are sleeping!
5) Some dog breeds have bigger litters than others. As a general rule, smaller breeds tend to have smaller litters, while bigger dogs give birth to more puppies. Our Coton who is about ten pounds, had a litter of three puppies with each weighing between 6-7 ounces.
6) Some puppies are born green. Yes this is true! In rare cases, the fur of a light-haired puppy can get stained by biliverdin, a green pigment found in dog placentas. It's not permanent, though. The green hue gradually disappears over the course of a few weeks.
7) Puppies don't find your yawns contagious. Ever notice that when somebody yawns, other people may follow suit? Contagious yawning, thought to be a sign of empathy, affects humans, baboons, chimps, and yes, dogs. However, young canines aren't susceptible to catching yawns from birth. In a 2012 study, Swedish researchers took a group of 35 dogs between 4 and 14 months old on closely monitored play dates, feigning yawns in front of each individual animal. Dogs that were less than 7 months old didn't react, yet many of the older dogs would respond with a yawn of their own. This pattern mirrors what happens with humans—children don't pick up the habit of contagious yawning until around age 4, when they start to develop social skills like empathy. These results suggest that dogs, too, may develop empathy over the course of their puppyhood.
8) All puppies are born with blue eyes. Because their eyes lack melanin—the pigment that determines eye color—puppies are born with blue eyes. While some puppies will retain the blue eye color for life, other pups' eyes will begin to show hints of their permanent color at around three to four weeks of age. It could take as long as three months for the color to fully develop however.
9) Puppies can have identical twins. However, scientists don't know exactly how common twin puppies are. It wasn't until 2016 that Kurt de Cramer, a South African veterinarian, noticed something unusual while performing a C-section on a pregnant Irish wolfhound. Normally, every puppy gets its own placenta, yet de Cramer noticed that two of the seven pups in this litter shared a single placenta. Testing later verified that the puppies were genetically identical. It was the first confirmed case of identical twin puppies in the world.
10) Looking at puppies can make you more productive. I found this very fascinating. In a 2012 research experiment participants were asked to look at pictures from one of three categories: tasty food snapshots, pictures of adult animals, or photos of puppies and kittens. Then, they were asked to play a board game that required lots of precision. As it turned out, people who'd just seen puppies and kittens had an easier time concentrating on the task at hand than study subjects who saw other types of images. Maybe we all need puppies in our offices! Or at least photos of puppies.
I hope you enjoyed reading some of these facts about puppies. National Puppy Day is coming up on Sunday, March 23rd. If you need some inspiration cleaning your house I will post puppy photos on Sunday!
