Dog’s age


 Since the 1950s, there has been popular theory that one dog year is the equivalent of seven human years. Even though this formula has been around for a surprisingly long time, the reality is not so cut-and-dried. One explanation for how this formula got started is that the 7:1 ratio seems to have been based on the statistic that people lived to about 70, and dogs to about 10. The American Veterinary Medical Association breaks it down like this:

  • 15 human years equals the first year of a medium-sized dog’s life.

  • Year two for a dog equals about nine years for a human.

  • And after that, each human year would be approximately five years for a dog.

Large dogs age at an accelerated pace, and “their lives seem to unwind in fast motion,” according to researcher Cornelia Kraus, an evolutionary biologist at the University of Göttingen in Germany. Scientists concluded that every 2 kilograms of body mass reduced a dog’s life expectancy by about a month.

    How did they get these parallels? Did they compare reproductive ability, brain development or some biological properties?

What dogs dream about

Obraz
Dr Deirdre Barrett, a clinical and evolutionary psychologist at Harvard Medical School, has released a study about what dogs dream about. She said it is possible that dogs dream just like humans about their everyday experiences, so there are a lot of chances they are dreaming about their owners. Although there's no way to know for sure what a dog is dreaming about, Dr Barrett says it is likely they are dreaming about running when their paws or legs begin to twitch or interacting with another dog or human when they start barking. She thinks that dogs have the same cycles of sleep as humans - light, deep and REM sleep stages. Dr Barrett says owners can try to improve their dog's dreams by exposing them to "happy daytime experiences" and providing them with a safe and comfortable environment to rest in the night. She suggested that the owners shouldn’t wake them up if they have a nightmare, because they can attack. Info source: https://www.mirror.co.uk/news/us-news/pet-...

Dogs breeding

Obraz
Selective breeding has occurred for thousands of years in numerous domesticated species, not just dogs. Our canine friends first developed breeding for specific behavioral traits, not conformational traits. However, where and when certain types of dogs originated is still uncertain.  Most dog breeds we recognize today were developed in the last 150 years, thanks to The so-called the Victorian Explosion. During this time in Great Britain, dog breeding intensified and expanded, resulting in many of our most recognizable breeds of dogs. The Victorians, influenced by Darvin’s ideas, became passionate about breeding for the ideal of a certain breed. Many of the conformational traits that we consider classic for a certain type of dog have their origins in this era. Breeding for conformational traits continued through the 20th century. The end result is the 400+ types of dogs recognized as distinct breeds. As we approach the third decade of the 21st century, technological advances hav...
