Gastric Dilation Volvulus (GDV) is a life threatening, acute condition that requires immediate medical attention.  Certain breeds are more prone to this condition: Boxers, Great Danes, Standard Poodles, Saint Bernards, Irish Setters, Dobermans, Weimaraners and Gordon Setters.  These breeds are considered deep-chested (large chest and narrow waist) but any similarly shaped dog can be at risk.

Diagnosis of GDV is made based on physical examination, history and abdominal x-rays.  Often GDV happens when a pet eats a large meal and then becomes very active.  Initially the dog may become restless, try to vomit or retch continuously but is unable to produce any vomit.  This is because the stomach has twisted, preventing anything entering and exiting the digestive system.  The pressure inside the stomach starts to increase and the dog may salivate and pant excessively.  As the patient’s condition progresses they become lethargic, have a swollen stomach and eventually collapse.  If not treated, the internal organs can be damaged and without timely treatment this condition is fatal. read more

Heartworm has been diagnosed in dogs in all parts of the world and is actually very common. This may be due to the fact that heartworm has a virtual 100% prevalence rate in unprotected dogs living in highly endemic areas. Heartworm, also known as Dirofilaria immitis, is transmitted by mosquitoes. The mosquito injects a microscopic larvae which grows into an adult worm six to eighteen inches long inside the heart of the affected dog.

The worms can cause mild symptoms, such as coughing, but with time, more severe symptoms such as congestive heart failure, weight loss, fluid build up in the abdomen, fainting spells, anemia, collapse, and death usually occur. read more

Hip dysplasia is a congenital disease that, in its more severe form, can eventually cause lameness and painful arthritis of the joints. It is caused by a combination of genetic and environmental factors. It can be found in many animals and, rarely, humans, but is common in many dog breeds, particularly the larger breeds. In the normal anatomy of the hip joint, the thigh bone (femur) joins the hip in the hip joint, specifically the caput ossis femoris. The almost spherical end of the femur articulates with the hip bone acetabulum, a partly cartilaginous mold into which the caput neatly fits. It is important that the weight of the body is carried on the bony part of the acetabulum, not on the cartilage part, because otherwise the caput can glide out of the acetabulum, which is very painful. Such a condition also may lead to maladaptation of the respective bones and poor articulation of the joint.  In dogs, the problem almost always appears by the time the dog is 18 months old. The defect can be anywhere from mild to severely crippling. It can cause severe osteoarthritis eventually. read more

Hookworms are small, thread- like parasites of the small intestine where they attach and suck large amounts of blood.  These parasites are found in almost all parts of the world, being common in dogs, and occasionally seen in cats.

Symptoms are usually diarrhea and weight loss.  The parasites can actually suck so much blood that they cause pale gums from anemia, and black and tarry stools.  Young puppies can be so severely affected that they die.  Infection can be by ingestion of breast milk from an infected mother, by ingestion of infective eggs, or by skin penetration of infective larvae. read more

Hypothyroidism is the natural deficiency of thyroid hormone and is the most common hormone imbalance of dogs. This deficiency is produced by several different mechanisms. The most common cause (at least 95% of cases) is immune destruction of the thyroid gland.  It can also be caused by natural atrophy of the gland, by dietary iodine deficiency, neoplasia (primary or metastatic) of the thyroid gland or (rarely) as a congenital problem. Hypothyroidism is most common in medium to large breeds of dogs that are middle aged (4 to 10 years) but can occur in any dog. read more

Leptospirosis is a serious, life-threatening disease caused by a spiral shaped bacteria. Dogs, cats, other animals and even people can be infected through exposure to urine, bite wounds, ingestion of infected flesh, or contact with contaminated soil, water and even bedding. Certain environmental conditions can favor the bacteria: standing water, rain, floods and warm moist weather. Pets living under these conditions, especially those who live primarily outdoors or are used for activities like hunting or herding are at a higher risk of being infected. The bacteria can quickly spread through the body causing symptoms like fever, joint pain, excessive drinking and general malaise. Eventually the bacteria settle in the kidneys or liver where it rapidly multiplies leading to organ inflammation, organ failure and possibly death. read more

A liver shunt is also named a PSS, portosystemic shunt, portacaval shunt or portosystemic vascular anomaly. This abnormality occurs when a pet’s venous blood from the intestine bypasses the liver. In the normal pet, blood vessels pick up nutrients from ingested material in the intestine and carry it to the liver to be processed. In the case of a shunt, an abnormal blood vessel carries this blood around the liver and dumps the nutrients directly into the general circulation. Toxins build up in the bloodstream as a result. The pet can be born with the shunt (congenital) or can develop it later (acquired). read more

Luxating patella is a condition where the kneecap (patella) moves out of its normal position. Luxating patella is one of the most common knee joint abnormalities of dogs, but it is only occasionally seen in cats. It may affect one or both of the knees. In some cases it moves (luxates) towards the inside of the knee, and in other cases it luxates towards the outside of the knee. Luxation to the inside of the knee is the most common form seen; it is most commonly seen in the small or miniature breeds of dogs such as Poodles, Maltese, Yorkies, and Chihuahuas. Luxations towards the outside of the knee are seen less frequently. It can be present in many breeds, but is seen especially in Newfoundlands. read more

There are many types of mites that infect dogs, cats, and other animals. Mites are microscopic arthropod parasites that, for the most part, infect the skin or mucous membranes. Mites can even be present on birds and reptiles. The most common mites that infect dogs and cats are ear mites, Demodex, scabies, and Cheyletiella.

Ear mites are very common on cats and are occasionally seen on dogs. They live primarily in the ear canals and can cause severe irritation. They are easily transmitted between pets, so if they are found in one pet, all pets in contact should be treated. A different species of ear mite can infect rabbits. read more

Excess weight is a serious health problem for dogs and cats and is common in many countries. The two main causes of obesity are too much food and too little exercise. Other contributing factors can be due to hormonal influences, certain genetic factors, and other disease processes.

If you pet is carrying extra weight, it can:

1. Increase the risk of heart disease by forcing the heart to work harder.
2. Increase the risk of arthritis as extra weight can stress the joints, cause joint pain, and make it harder for your pet to move around comfortably.
3. Obesity can cause breathing problems, skin and hair coat problems.
4. Especially in cats, obesity frequently leads to diabetes.

All of these problems can make your pet uncomfortable and limit the way they interact with you and other family members.

Treatment is to rule out and treat any medical causes, such as hypothyroidism. Reducing caloric intake and increasing exercise can help your pet successfully lose weight. Lifestyle changes and a weight loss program are essential. Your veterinarian can help determine if your pet is too heavy and provide guidelines for achieving their ideal weight. Slentrol is an oral weight loss drug for obese dogs that are not able to lose weight by other means. read more
