"Hot spots can dramatically increase in size in a very short period of time." Dogs lick the area around the rectum and can cause hot spots under or on top of the tail. Infected or impacted anal glands are painful and annoying. Dogs also lick or chew at degenerating joints much like people rub a sore knee to relieve the pain, creating hot spots in the process. When the dog licks the abrasion, a hot spot erupts. Lying on one side creates abrasions over pressure points, like hips or hocks (ankles), where bony protrusions have little muscular padding, especially in elderly dogs with diminishing muscle mass. Dogs with arthritis or back problems tend to lie down much of the time. When they lie down, the feet and forearms are right under their faces so hot spots often occur there. Instead of biting their fingernails, bored dogs lick areas that are easily accessible. This sets up a perfect environment for a hot spot.

Matted fur prevents air from reaching the skin and retains water after a dog swims or gets caught in the rain so the skin stays wet. Dogs with unkempt hair coats bite at tangles, creating open wounds. Primary skin infections also caused by bacteria or yeast may incite the dog to scratch an area so much that a secondary hot spot forms. Bacteria or yeast in the ear canal can be so irritating that the dog scratches at his ear, creating hot spots on the ear flap, behind the ear, or on the neck. Reactions to insect bites from fleas, mites ( Sarcoptes, Cheyletiella), or other small insects (e.g., caterpillars, bees, wasps, lice, gnats, or mosquitoes).Allergies including food allergies or inhalant allergies that cause itching.Many things can cause the initial itch in dogs including: Hot spots are usually caused by self-trauma when a dog scratches an itch so vigorously that it creates an open wound. These painful, itchy, smelly sores may be very obvious or may be hidden beneath matted fur. Hot spots can be found anywhere on a dog’s body, but the most common sites are the head, legs, and hips. These photos confirmed that Mars was a dusty and dry world.Canine hot spots, also known as pyotraumatic dermatitis or acute moist dermatitis, are red, inflamed skin lesions that appear quickly, ooze, and may contain pus. In 1965, NASA’s Mariner 4 became the first spacecraft to reach Mars and sent back 22 photos of the planet’s surface to Earth. The theory of these man-made canals has been subsequently disproved – they were optical illusions that resulted from the poor-quality telescopes of the time. The idea was picked up by many influential scientists of the time, including Percival Lowell, who decided these canals were built by Martians to bring water from the polar caps to the equatorial regions. This name resulted in the misinterpretation that there were actually man-made canals on Mars, akin to the Suez Canal that was completed not that long before, in 1869. In the late 1800s, Schiaparelli observed channels on Mars and named them ‘canali’. The observations of one of these scientists, the Italian Giovanni Schiaparelli, accidentally popularised the idea that there was intelligent life on Mars. With the development of larger telescopes and observatories throughout the world in the 1800s, scientists were able to study the planets in our Solar System in greater detail than ever before. It takes 584 days to go through one complete cycle of Venus’ phases- this is the amount of time it takes the planet to overtake Earth in its orbit.
Eventually, we see nothing but an illuminated crescent, as Venus reaches its closest approach to Earth. As Venus approaches Earth, we see less of its dayside as its phase begins to change. When this happens, from Earth’s view, Venus is fully lit by the Sun. As a result, sometimes Venus is on the other side of the Sun from Earth. Venus’ orbit of the Sun is closer than the Earth’s, so it completes one orbit much faster than Earth does (225 days in comparison to our 365.25). Thanks to the observations of Galileo Galilei, it was discovered that Venus was just one planet and goes through phases much like the Moon. To add to the confusion, when observed through a telescope, at times, parts of the disk of Venus appeared to be missing. These two different ‘stars’ even had names, Phosphorus and Hesperus. This led to some ancient astronomers believing they were seeing two separate bodies in the sky.
Throughout the year, Venus alternates between being visible in the morning and the evening sky.
