zoonotic diseases in dogs |

Conjunctivitis* is inflammation of the conjunctiva. In dogs it is most commonly caused by mechanical irritation (such as by entropion, ectropion, or trichiasis), allergies, and keratoconjunctivitis sicca. Any bacterial infection is usually secondary.[70]
Ear infections are common in dogs, particularly breeds with hanging ears, such as Beagles, and dogs with narrow ear canals, such as Cocker Spaniels. Other predisposing factors include allergies, ear parasites, and hypothyroidism.[74]
Campylobacter spreads through contaminated food (meat and eggs), water, or contact with stool of infected animals. Dogs infected with Campylobacter might show no signs of illness at all or might have diarrhea and a slight fever.
Epilepsy in dogs can be a primary, idiopathic, inherited disorder or secondary to previous head trauma or CNS infections. Idiopathic epilepsy is commonly found in breeds such as German Shepherd Dogs, Beagles, and Dachshunds. The most common sign recurring generalized seizures beginning at a young adult age.[56]
Bilious vomiting syndrome is vomiting in response to bile-induced inflammation of the stomach. Bile salts interfere with the gastric mucosal barrier, allowing acid to irritate the stomach lining and cause gastritis.[146]
What to look for: Since there are so many kinds of allergies dogs can have (from food to flea/tick bites and a wide range of other possibilities), it’s important to look for any change in behavior when exposed to something new. If your dog goes a few days showing lack of energy, has a consistent cough or sneeze, or if anything else seems out-of-place, you might be dealing with allergies.

Distichia (including ectopic cilia) is an eyelash that arises from an abnormal spot on the eyelid. Distichiae usually cause no symptoms because the lashes are soft, but they can irritate the eye and cause tearing, squinting, inflammation, and corneal ulcers.[62]
Pick a dog that is bright, alert, and playful. Dogs and puppies should have shiny, soft fur that is free of stool. Signs of illness in a dog include appearing sluggish or depressed, having diarrhea, abnormal breathing, and fluid running from its eyes or nose. Make sure to take your new dog or puppy to the veterinarian within a few days to a week after adoption for a health visit.
Developmental orthopedic diseases include panosteitis and hypertrophic osteodystrophy. Panosteitis occurs in large and giant breed dogs usually between the age of five and fourteen months and manifests as fever, pain, and shifting leg lameness. Hypertrophic osteodystrophy is also seen in young large and giant breed dogs and is characterized by pain, lameness, fever, and swelling of the long bone metaphysis.
Ever think, “I should Spin more,” and then remember how much you hate Spinning? Same for dogs. Not every dog is a runner or a swimmer or will want to play fetch. In fact, says Case, “If you haven’t started your dog swimming before the age of 1 or 2, it’s not going to like it”—even if it has webbed feet. “There are many more owners who want their dogs to swim than there are dogs that want to get in the water.” Tip: There’s no real data on the optimum cardio workout for dogs, says Kerns, “but the more you can get your dog outside—with the sun overhead and grass under its paws—the better.”

People who become infected with leptospirosis might not have any signs of the disease. Others will have nonspecific flu-like signs within 2-7 days after exposure. These symptoms usually resolve without medical treatment, but can reappear and lead to more severe disease.
Inflammatory bowel disease (IBD)* is a group of diseases in dogs that are idiopathic and characterized by the presence of inflammatory cell infiltrates in the stomach and/or intestinal walls. It is a common condition. Signs include vomiting, diarrhea, and weight loss. Treatment is with dietary modification and use of medications such as corticosteroids, metronidazole, sulfasalazine, and azathioprine.[145]

Legg-Calvé-Perthes syndrome, also known as Perthes disease or avascular necrosis of the femoral head, is characterized by a deformity of the head of the femur and hip pain. It occurs in small breed puppies.[6]
Masticatory muscle myositis (MMM) is an inflammatory disease in dogs affecting the muscles of the jaw. Signs include swelling of the jaw muscles and pain on opening the mouth. In chronic MMM there is atrophy of the jaw muscles, and scarring of the masticatory muscles due to fibrosis may result in inability to open the mouth (trismus).[6]

Poisoning with pain medications is common. Aspirin, paracetamol (acetaminophen, Tylenol), ibuprofen (Advil), and naproxen (Aleve) can all cause severe clinical signs in dogs, including vomiting blood, diarrhea, and abdominal pain.[57][58][59][60] Specifically, aspirin can cause metabolic acidosis and bleeding disorders, acetaminophen can cause liver disease, ibuprofen can cause kidney disease, and naproxen can cause ulcers in the stomach, which can perforate. Treatment depends on the clinical signs.
What to look for: No one wants to think about their dog getting cancer. It is one of the biggest killers in dogs and one of the most expensive diseases to treat. Look out for unusual odors, lumps, drastic weight loss, or long-lasting changes in behavior.

Most diseases that affect dogs or humans are not transferable between the two species. Diseases that can be transmitted from animals to humans are terrmed zoonoses. A well-known zoonosis is rabies, a viral infection transmitted through a bite. A common bacterial zoonosis is leptospirosis, transmitted through urine. Some of the most important zoonoses are parasitic. Zoonotic intestinal parasites transmitted through contact with feces include Toxocara canis (the canine roundworm), which causes toxocariasis, visceral larva migrans, and ocular larva migrans, and hookworms, which can cause cutaneous larva migrans. Zoonotic skin parasites include scabies, caused by the mite Sarcoptes scabiei. The most common zoonotic fungal disease is ringworm, caused in this case by Microsporum canis.
Subaortic stenosis, or SAS, is a genetic ailment that causes a narrowing of the passage of blood between the heart and the aorta. This leads to heart problems and sometimes sudden death. It affects larger breeds such as the Newfoundland Dog and the Golden Retriever.[15] In some dogs, such as collies, the blue merle or harlequin coloring is actually the heterozygote of a partially recessive gene preventing proper development of the nervous system; therefore, if two such dogs are mated, on the average one quarter of the puppies will have severe genetic defects in their nervous systems and sensory organs ranging from deafness to fatal flaws.

As the name suggests, an infected mosquito injects a larva into the dog’s skin, where it migrates to the circulatory system and takes up residence in the pulmonary arteries and heart, growing and reproducing to an alarming degree. The effects on the dog are quite predictable, cardiac failure over a year or two, leading to death. Treatment of an infected dog is difficult, involving an attempt to poison the healthy worm with arsenic compounds without killing the weakened dog, and frequently does not succeed. Prevention is much the better course, via heartworm prophylactics which contain a compound which kills the larvae immediately upon infection without harming the dog. Often they are available combined with other parasite preventives.
Signs of vestibular disease include head tilt, circling, nystagmus (an abnormal movement of the eyes), and difficulty or inability to stand. These clinical signs are similar to those seen in humans experiencing vertigo. Vestibular disease may have many causes. Elderly dogs are susceptible to an idiopathic (meaning due to unknown causes) form of vestibular disease commonly called “old dog vestibular disease” or idiopathic peripheral vestibular disease. The signs may improve rapidly or take a few days. Less commonly, vestibular signs can also be caused by inner ear disease, a brain tumor, a stroke, or other causes. The major risk with idiopathic peripheral vestibular disease is that the dog is often unable to eat, drink, or go outside to urinate or defecate. These cases must receive supportive therapy of intravenous fluids and nutrition; a light sedative is sometimes administered, as the dog may be very stressed by the experience.
Sporotrichosis is a fungal disease caused by Sporothrix schenckii that affects both dogs and humans. It is a rare disease in dogs, with cat and horse infections predominating in veterinary medicine. The disease in dogs is usually nodular skin lesions of the head and trunk.[22]
Common treatments include surgery, chemotherapy, radiation and immunotherapy or a combination of therapies. Success of treatment depends on the type and extent of the cancer and the aggressiveness of the therapy. Of course, early detection is best.
2. Heartworm: Heartworm is a disease spread by mosquitoes and it has been diagnosed in all 50 states. While it is much more common in dogs, cats can also acquire the disease. If the infection is caught early enough in dogs, it can generally be treated, but there is no cure for feline heartworm disease. Therefore, the best way to keep your pets heart free of potentially deadly worms, is through a monthly preventative, prescribed by your veterinarian.

Depending on the size of your pup, some health problems are more prevalent than others. For instance, big dogs tend to deal with more bone and joint problems, whereas smaller dogs tend to suffer more with organ and breathing disorders. Again, each breed is unique, but it is important to understand what common dog illnesses and health issues affect your pet. See below for the most common types of dog health issues and make sure to take immediate action if you think something serious is wrong with your dog.
Our dogs are faithful companions, and they depend on us for good care. To help your canine friend live a healthy life, you should know some of the most common health problems dogs face, their signs, and what you can do about them.

Feeding table scraps to a dog is generally not recommended, at least in excess. Just as in humans, a dog’s diet must consist of the appropriate mix of nutrients, carbohydrates, and proteins in order to give them the minerals and vitamins that they need. Dogs get ample correct nutrition from their natural, normal diet; wild and feral dogs can usually get all the nutrients needed from a diet of whole prey and raw meat. In addition, a human diet is not ideal for a dog: the concept of a “balanced” diet for a facultative carnivore like a dog is not the same as in an omnivorous human. Dogs will usually eat all the scraps and treats they are fed: usually too much food. While not all human delicacies are acutely toxic to dogs (see above), many have the same chronically unfortunate results as they do for humans.

Luxating patella is a medial or lateral displacement of the patella, or kneecap. It is strongly suspected to be inherited, but can also result from trauma.[36] It is more common in smaller breeds of dogs [1]
Subvalvular aortic stenosis (Subaortic stenosis; SAS) is a congenital disease in dogs characterized by left ventricular outflow tract obstruction by a discrete ring or tunnel of fibrous tissue immediately below the aortic valve. It is inherited in Newfoundlands, and also found in Golden Retrievers, Rottweilers, Boxers, Bulldogs, German Shepherds, and Samoyeds. Signs include a left basilar systolic heart murmur, weak femoral pulse, fainting and exercise intolerance. Dogs with severe SAS are predisposed to dying suddenly.[49]
Vets4Pets, which has nearly 400 practices across the UK, is supporting the research work carried out by Anderson Moores Veterinary Specialists to help understand the disease, how it can be treated and possibly prevented.

Leishmaniasis is a protozoan disease of people and animals. It is transmitted by sandflies and is uncommon in North America. The two forms of the disease are visceral and cutaneous. The cutaneous form of leishmaniasis is most common in people and appears as one or more painless ulcers on the skin. Visceral leishmaniasis is less common and is characterized by fever, weight loss, enlarged spleen, and anemia. Dogs can develop both forms at the same time and have a variety of symptoms.
One of the most common fungal diseases in dogs is ringworm, or dermatophytosis, an infection of the skin, hair, or nails. There are three fungal species that cause ringworm in dogs. About 70 percent of infections are caused by Microsporum canis, 20 percent by M. gypseum, and 10 percent by Trichophyton mentagrophytes. Signs include hair loss and scaling of the skin. Treatment for localized ringworm is not always necessary as the disease is self-limiting, but the cliinical course can be shortened by using topical miconazole or clotrimazole. Generalized infections, most commonly seen in immunocompromised dogs, can be treated with oral antifungal drugs such as griseofulvin or itraconazole. Infection can spread to humans.[9]
Since the disease was first detected in 2012 in the UK the number of cases of Alabama dog rot in dogs has risen. The most serious outbreak was in the New Forest region of Hampshire but there have also been reported cases in several other counties, with the most recent cases reported Gloucestershire, Monmouthshire, Devon, Dorset, Cheshire, Warwickshire, Greater Manchester and Worcestershire.

Anal fistulae*, known as perianal fistulae in dogs, are most common in German Shepherd Dogs. They are characterized by draining tracts in the skin around the anus. The cause is unknown. Surgical treatment is common, but recently use of cyclosporine in combination with ketoconazole has been shown to be effective.[143]
If a lump is present, the first step is typically a needle biopsy, which removes a very small tissue sample for microscopic examination of cells. Alternately, surgery may be performed to remove all or part of the lump for diagnosis by a pathologist.
