Welcome back to Animal Expert. Today we're going to tell you 20 interesting facts about dogs that you probably didn't know. Let's take a look at them. 1.

On the other hand, their taste and vision are poorly developed compared to people's. 9. They can diagnose diseases with their sense of smell. Although it may seem incredible they can.

Despite communicating with a mainly non verbal language, dogs are capable of understanding up to 150 words if they are stimulated and educated properly. 13 Their life expectancy varies greatly. Large dogs, due to their higher growth rate and the greater metabolic wear and tear on their bodies, age at a significantly faster rate than small dogs, which is why they are animals with shorter lives. 14 Their body temperature is higher than ours. The normal temperature range for dogs is between 38 and 39 degrees Celsius, which is slightly higher than that of people. In addition, the temperature increases in pregnant dogs but decreases 24 hours before giving birth. 15 Their canine genome was sequenced in 2005, just two years after the Human Genome Project announced that the sequencing of the first human genome had been completed. Sixteen Female dogs are monoestrus, which means that they have a heat cycle that is not associated with a specific season. As a general rule, female dogs have two heat cycles per year, although it is also considered physiological for them to have one or three heat cycles per year. 17 they are born blind and deaf. Puppies have incomplete motor and sensory nervous development. Their sense of sight, hearing, and their ability to thermoregulate are barely developed at birth. 18 they do not have sweat glands on their skin except on the pads on their feet. Since they have such few and underdeveloped sweat glands, they barely lose any heat through the evaporation of sweat. For this reason, they use mechanisms such as panting to reduce their temperature. 19. They hate some things about their humans. For example, since their senses of hearing and smell are much more sensitive, they are deeply bothered by shouting and loud noises. In addition, hugs can be uncomfortable for them because they feel trapped. 20.
