Facts About Puppies!

1. THE WORD PUPPY HAS FRENCH ROOTS - Etymologists think the term puppy may come from poupeé, a French word meaning doll or toy. The word puppy doesn't appear to have entered the English language until the late 16th century—before that, English speakers called baby dogs whelps. William Shakespeare's King John, believed to be written in the 1590s, is one of the earliest known works to use the (super cute) term puppy-dog.

2. PUPPIES EVOLVED TO BE BLIND AND DEAF AT BIRTH - Puppies are functionally blind and deaf at birth. On day one, their eyes are firmly shut and their ear canals closed. Why? In brief, it’s part of an evolutionary trade-off. Since pregnancy can hurt a carnivore's ability to chase down food, dogs evolved to have short gestation periods. Brief pregnancies meant that canine mothers wouldn't need to take prolonged breaks from hunting. However, because dog embryos spend such a short time in the womb (only two months or so), puppies aren't born fully developed—and neither are their eyes or ears.

3. PUPPIES HAVE BABY TEETH, TOO - Like many new-born 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.

4. PUPPIES TAKE A LOT OF NAPS - Like children, puppies need a lot of sleep—up to 15 to 20 hours of it 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. Puppy owners should also establish a designated sleeping space on their pup's behalf so they can snooze undisturbed.

5. CERTAIN dog BREEDS ARE USUALLY BORN BY C-SECTION - Purebred dogs can exhibit some extreme bodily proportions, which doesn't always make for easy births. Breeds with atypically large heads are more likely to be born by C-section than those with smaller skulls. A 2010 survey of 22,005 individual dog litters in the UK found that terriers, bulldogs, and French bulldogs had Caesarean births more than 80 percent of the time. The other breeds with the highest rates of C-sections were Scottish terriers, miniature bull terriers, Dandie Dinmont terriers, mastiffs, German wirehaired pointers, Clumber spaniels, and Pekingeses, according to the study.

6. 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. The biggest litter on record was born to a Neapolitan mastiff that gave birth via Caesarean section to a batch of 24 puppies in Cambridgeshire, UK in 2004. In rare cases, very small dogs do give birth to relatively large litters, though. In 2011, a Chihuahua living in Carlisle, England, gave birth to a whopping 10 puppies—twice as many as expected. Each weighed less than 2.5 ounces.

7. SOME PUPPIES ARE BORN GREEN - Sometimes, a puppy in a light-coloured litter can be born green. On two different occasions in 2017, in fact, British dogs made the news for giving birth to green-tinted puppies. In January, a 2-year-old chocolate lab in Lancashire, UK gave birth to a litter that included a mossy-green pup. Her owners named her FiFi, after Fiona, the green-skinned ogre from Shrek. Just a few months later, a golden retriever in the Scottish Highlands also gave birth to a puppy with a green coat, a male named Forest. How did the puppies end up sharing a shade with Kermit? 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.

8. 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. But as research published in Animal Cognition suggests, young canines aren't susceptible to catching yawns from birth. In the 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.

9. DALMATIAN PUPPIES ARE BORN WITHOUT SPOTS - Beloved by firefighters, Disney fans, and George Washington, Dalmatians arguably have the most recognizable coat of any dog breed. Or at least, full-grown Dalmatians do. As puppies, they're born white and spot-less. The markings usually begin to show up after four weeks or so.

10. PUPPIES KNOW HOW TO MANIPULATE YOU WITH THEIR EYES - Those adorable "puppy eyes" aren't an inadvertent expression of canine emotion; they're a deliberate ploy to get our attention. Puppies (and adult dogs) have learned that raising their eyebrows, which makes their eyes appear bigger and sadder, makes them magnets for human attention. According to one study from 2017, dogs are more likely to make dramatic facial expressions like puppy-dog eyes when they know humans are watching. And it works. Research has shown that shelter puppies who put on such faces get adopted more quickly than dogs that show other behaviours, like wagging their tails.

11. PUPPIES CAN HAVE IDENTICAL TWINS - Scientists don't know how common identical twin puppies are, because until very recently, no one was able to prove that they existed at all. In 2016, 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.
