The spine supports the nervous system of dog’s body. Ribs support lungs and heart. Skeletal system enables movement of body parts especially hind and fore limbs. Muscles attached to the bones help in the movement of bones. Dog’s have strong muscles in their hind limbs. This enables them to jump high and run fast. However, you must be careful while

With strong sense of smell, they mark their territory, communicate and recognize other animals. Some breeds have comparatively stronger sense of smell like Labrador retrievers.
Sound: Dogs can detect noises beyond the limit of human ears. Some breeds have ears which can be moved around for better sound detection. They can identify even the smallest of sounds. Like human beings, dog’s ears also help in maintaining balance of body. Here are some interesting facts about canine ears:
· It takes more than eighteen muscles for a dog to move its ears!
· 30% of Dalmatians are deaf with one or both ears.
· Dogs like Saint Bernard with big heads and large ears are best at hearing subsonic sounds.
Eyes: Dog’s vision is adapted for hunting. It is designed to see fast moving animals. The field of vision among dogs varies largely on the breed. Some breeds like Pekinese have smaller field of vision as their eyes are protruded more unlike other breeds. On the other hand breeds like greyhound have a large field of vision. Dog’s have third eyelid unlike human beings. The third eyelid, called ‘haw’ keeps eyes lubricated and protected. Some studies have confirmed that dogs can see better in low light.
Taste: Unlike human beings, dogs do not have highly developed taste buds. However, the taste buds can detect sour, sweet, salty and bitter taste.
The respiratory system: Respiratory system of dogs consists of small chambers in their lungs called alveoli. It warms and filters the oxygen as it enters their lungs. Like human beings, dog’s respiratory system expels carbon dioxide in exchange with oxygen.
Cardiovascular System : The cardiovascular system of dogs includes heart, veins and arteries for supplying blood to the entire body. It is responsible for transportation of nutrients, oxygen to other body parts. Blood is required to keep dog’s body warm.
Urinary system: Urinary system maintains water balance and eliminates toxins from body. It consists of kidneys which filter blood and remove toxins from body. Excess water and toxins eliminated by kidneys are transported to the urinary bladder. Urinary bladder eliminates the store toxins and water out of the body in the form of urine. The chemicals present in urine help dogs to mark their territory and to communicate with other dogs. Infection in urinary system is a common problem in older dogs.

Dogs are blessed with strong digestive juices in their stomach which helps in easy digestion of food. Dog’s teeth are adapted to suit the requirements of hunting. They have large canines to grab the prey and flat teeth at the back to help them in chewing the food. ( ) Tips For Selecting Good Dog Food

Male dogs can reproduce anytime of the year while female dogs can do it twice a year. Pregnancy is about 60 days.

It is divided into main parts- Brain and spinal cord. Brain controls breathing and temperature of body. It plays a significant role in the complex behavior of dogs. It controls their motivation, perception and learning abilities. The spinal cord acts as conductor for reflex actions. Reflexes play an important role in a dog’s day to day life.
