Facts Known also as hypoadrenocorticism, hypocortisolism, and adrenal insufficiency, Addison’s Disease was first found in humans and then later found in dogs. The disease is described as an endocrine system disorder and takes place when the production of corticosteroid hormones decreases to such an amount that the body is no longer able to function normally.
FactsAdrenal Gland Cancer, also known as Pheochromocytoma, involves the presence of a tumour in the adrenal gland. This tumour affects the glands by causing them to make an excess of particular hormones. Other ways the tumour can affect the animal is to cause an increase in blood pressure, heart rate, and even the breathing rate.
Facts Red blood cells (RBC) work to deliver oxygen to the dog’s tissues. This is done when the blood cells pick up oxygen in the lungs and release it to the body’s cells when the RBCs squeeze through the capillaries. This “pick up” is performed by the iron-containing hemoglobin (also spelled haemoglobin) biomolecule. The hemoglobin
Facts The aortic valve is one of four valves of the heart. De-oxygenated blood enters the right atrium via the vena cava. The heart contracts and pumps the blood through the tricuspid valve into the right ventricle. After another pump of the heart, the blood goes into the lungs to become oxygenated. Once oxygenated, the
Telltale signs of asthma in a dog are not unlike those found in humans. A dog that seems to be wheezing, coughing and having difficulty breathing may be suffering of an obstruction in its airways, causing an asthma attack. People may be surprised to know that just like humans, dogs can develop asthma, and more
Facts Red blood cells, also called RBCs, are the most common blood cell in the circulatory system. They contain hemoglobin (also spelled haemoglobin), a biomolecule containing iron, that binds to oxygen in the lungs and delivers it to the rest of the body’s cells. Once the oxygen is released, the RBC then picks up carbon
Facts Babesiosis (also called Babesia infection) is a disease passed to mammals via ticks. The Babesia parasite is a microscopic organism that takes up residence the dog’s red blood cells and eventually destroys the RBCs, which causes the animal to become anemic. Babesiosis is the second most common blood parasite disorder of all mammals, although
FactsBird Flu, also known as Avian Influenza or H5N1, is a viral infection that was found in large amounts of wild birds and poultry in Africa, Asia, and Europe. H5N1 is in fact a subtype of the Influenza-A virus, which causes the flu in birds. It is called “Bird Flu” because the virus has found
FactsBrachycephalic airway syndrome is a respiratory condition that most commonly affects certain breeds of dogs. It refers to a number of upper airway issues found in these breeds. By definition brachycephalic means a broad, short head, and these affected dogs usually have an elongated soft palate (which is when the soft palate is so long
Facts A dog that is suffering from bronchitis is suffering from an inflammation in its bronchial tubes. This inflammation can happen in one or both bronchi (respiratory airways). There are two forms of bronchitis which are acute and chronic. The acute form is most often due to a viral or bacterial infection. In many cases
Cancers are diseases that occur in most animals, including dogs. A cancer results when a cell in a dog's body starts to replicate uncontrollably, forming clumps of abnormal or cancerous cells called tumours. These cancer cells escape detection and trick the natural killer cells of the body's immune system into not attacking and destroying them.
Facts A dog's immune system is its defense system, made up of antibodies, white blood cells, and other substances. This defense system works to reject foreign bodies and attack infections. It differentiates between "self" cells and "non-self" cells by markers - called antigens - located on the surface of every cell in the dog's body.
Hormones are chemical messengers that influence the activity of cells and tissues all round the body. The first hormones to be identified were those produced by discrete, visible glands, such as the thyroid and the pituitary. Later, scientists discovered other messengers, including the brain biochemicals dopamine and serotonin, and trace chemicals called cytokines. New cytokines
Dogs use their mouth and teeth not only for eating, but also for defence, for grooming, for showing affection to others, or simply to explore, taste, play, and amuse. As a consequence there is a wide variety of potential problems. Mouth infections Infection or inflammation in the mouth - stomatitis - can be caused by
Problems may occur anywhere in the respiratory system - from a tickle in the nose producing a sneeze, to trauma in the chest causing laboured breathing and clinical shock. Infections and disorders can occur in either the upper respiratory system, including the nose and windpipe, or in the chest and lungs - the lower respiratory
Damage to the spinal cord, whether it occurs spontaneously or results from an accident, can cause loss of voluntary muscle movement, changes in spinal reflexes or muscle tone, muscle shrinkage, and loss of touch and pain sensations. This damage may be irreparable. Paralysis Paralysis is often caused by traumatic spinal cord injury from road traffic
Facts When a dog is diagnosed with Diabetes Insipidus it is essentially suffering from a disorder of water balance because of decreased production/levels of antidiuretic hormone (ADH). It causes the dog to get rid of highly diluted urine in huge abnormal quantities, because ADH is what regulates the kidneys’ power to absorb water. The disease
Facts Diabetes Mellitus is a disease which occurs in dogs when the pancreas fails to produce enough insulin. In some cases, insulin production stops all together. Insulin tells the body how to properly use proteins, fats, and sugars. This lack of insulin means the liver doesn’t know when to stop glucose production and no longer
Diarrhea, the most common medical condition associated with the intestines, can occur as a result of damage to the digestive system, but may simply be your dog's way of coping with an ingested irritant. Diarrhoea may be accompanied by vomiting, tummy rumbles, pain, burping, or passing wind, and it may contain mucus or blood. Get
Facts In a properly working heart, blood flows into the right atrium and is pumped into the right ventricle. After that, it goes to the lungs where it picks up oxygen and then flows back into the heart’s left atrium. Pressure causes the oxygenated blood to flow into the left ventricle and out of the
The brain, through its connections with the spinal cord and peripheral nerves, coordinates all activities, thoughts, senses, feelings, emotions, movement, and body functions. If the brain is damaged, this can lead to behaviour changes, seizures, loss of coordination, paralysis, or coma. Brain injures Brain injuries are frequently caused by physical injuries, especially as a result
The ear is a vulnerable part of a dogs body. The outer ear flap is easily damaged, while the ear canal encourages the accumulation of wax, debris, and water, and provides an access point for a variety of infections. Common IndicatorsDogs with ear problems may show any of the following clinical signs:ï¿½ Head and ear
Eye disorders account for a large number of visits to the clinic because they are amongst the easiest problems to recognize and always appear potentially worrisome. Understanding the signsCheck with your vet if you notice any of the symptoms below: they may simply indicate an allergy, but can also be caused by more serious concerns,
Vomiting and diarrhoea are two of the most common problems seen by vets. Their causes are often trivial, but in some cases they can be life threatening. Knowing a little about the different types of vomiting will help you decide if your dog needs veterinary attention. Acute vomiting: dogs "cure" themselves of their scavenging indiscretions
