anal tumors in dogs |

Although the name suggests otherwise, ringworm isn’t caused by a worm at all—but a fungus that can infect the skin, hair and nails. This highly contagious disease can lead to patchy areas of hair loss on a dog and can spread to other animals—and to humans, too.
Ehrlichiosis is a bacterial disease that affects animals and people and is transmitted by ticks. Dogs show variable signs that include depression, loss of stamina, stiffness and reluctance to walk, and coughing.

Cancer is a class of diseases in which cells grow uncontrollably, invade surrounding tissue and may spread to other areas of the body. As with people, dogs can get various kinds of cancer. The disease can be localized (confined to one area, like a tumor) or generalized (spread throughout the body).
Atrial septal defect* is a hole in the division between the heart atria (upper chambers of the heart). It is an uncommon abnormality in dogs. Most are not clinically significant, but large defects can cause right heart failure and exercise intolerance. Standard Poodles are the most common breed diagnosed with ASD in the USA.[49]
Canine parvovirus is caused by infection with CPV, most often, CPV-2a or CPV-2b. All dogs are at risk for developing canine parvovirus. Puppies less than 4 months old and dogs that have not been vaccinated against the virus are at increased risk for infection.
Salmonella spreads to people through contaminated food (eggs and meat) or contact with stool of certain animals including dogs. Salmonella infections have been linked to some brands of dry dog food, treats, and chew toys like pig ears and to “raw food” diets for dogs. While it usually doesn’t make the dogs sick, Salmonella can cause serious illness when it is passed to people.
Genetic conditions are a problem in some dogs, particularly purebreeds. For this reason many of the national kennel clubs require that dogs with certain genetic illnesses or who are deemed to be carriers cannot be registered. Some of the most common conditions include hip dysplasia, seen in large breed dogs, von Willebrand disease, a disease that affects platelets that is inherited in Doberman Pinschers, entropion, a curling in of the eyelid seen in Shar Peis and many other breeds, progressive retinal atrophy, inherited in many breeds, deafness, and epilepsy, known to be inherited in Belgian Shepherd Dogs, German Shepherd Dogs, Cocker Spaniels, and St. Bernards.[14]
Visit a veterinarian for routine evaluation and care to keep your dog healthy and prevent infectious diseases. Keeping your dog on a monthly preventative for fleas, heartworms, and other parasites, and up to date on vaccinations can help prevent certain diseases.
My human went to the pumpkin patch and brought back several lovely pumpkins for the porch. I was bummed because I couldn’t get her to throw them like balls for me. They looked like balls. She saw how disappointed I was and got me this pumpkin dog toy. She throws it and I chase it, and we both smile. And I leave the real pumpkins alone.
“If you think your dog is too skinny, it’s probably the right weight,” Case say. Dogs with excess weight are more prone to joint problems and diabetes, among other health issues (sounds familiar). How to tell if Fluffy is chubby? “It’s all about the feel,” she adds. “Ribs shouldn’t be visible, but easily felt.” Tip: Rub your hands up and down your dog’s flank. You should feel the ridges of its ribs without having to push in to find them.
Ringworm is a fungal skin disease that in dogs is caused by Microsporum canis (70%), Microsporum gypseum (20%), and Trichophyton mentagrophytes (10%). Typical signs in dogs include hair loss and scaly skin.[21]
Some dogs have food allergies just as humans do; this is particular to the individual dog and not characteristic of the species as a whole. An example is a dog becoming physically ill from salmon; many humans likewise have seafood allergies.
Newborn puppies receive antibodies from their mothers that help provide immunity, but immunity to CPV wears off before the puppies’ immune systems are developed enough to destroy the virus and fight off infection.

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.
Tracheal collapse is characterized by incomplete formation or weakening of the cartilagenous rings of the trachea. It is most common in small and toy breeds. Signs include a cough (often called a “goose honk cough” due to its sound), especially when excited.[6]
Diagnosis of canine parvovirus is based on symptoms, physical examination, and laboratory tests. In puppies and dogs that have not been vaccinated, CPV infection often is suspected when bloody diarrhea, loss of appetite, and vomiting develop suddenly. Physical examination may reveal signs of dehydration (e.g., lethargy, sunken eyes, dry gums, rapid heart rate, concentrated urine), fever, abdominal discomfort, swollen lymph nodes, and weight loss.
Antifreeze* is very dangerous to dogs and causes central nervous system depression and acute renal failure. Treatment needs to be within eight hours of ingestion to be successful.[168] See Ethylene glycol poisoning.
“Food is one way we show our dogs love,” says Case, “so banning people from feeding their dogs extras doesn’t work.” Even so, just as you can’t afford the effects of too many snack sessions, neither can your pup. Limit food beyond what’s in your dog’s daily diet—including that tiny bit of leftover salmon from your plate and even training treats—to no more than 10% of its calorie need, Case says. Tip: Make training treats small enough so your dog can down them quickly and delicious enough that they’ll count as a real reward.
“We would also encourage all vets and owners to work with David and his team at Anderson Moores so we can have a clear picture of confirmed cases in the UK, to help prevent more dogs falling victim to this terrible disease.”

Congestive heart failure* is the result of any severe, overwhelming heart disease that most commonly results in pulmonary edema (fluid in the lungs), pleural effusion (fluid around the lungs), and/or ascites (fluid in the abdomen). It can be caused by the above two diseases, congenital heart defects such as patent ductus arteriosus, pulmonary hypertension, heartworm (Dirofilaria immitis) disease, or pericardial effusion. Signs depend on which side of the heart is affected. Left-sided heart failure results in rapid and/or difficulty breathing and sometimes coughing from a build-up of fluid in the lungs (pulmonary edema). Right-sided heart failure results in a large liver (congestion) and build-up of fluid in the abdomen (ascites), uncommonly fluid around the lungs (pleural effusion), or, rarely, peripheral edema.[51]
The first sign of Alabama Rot is skin sores that have not been caused by a physical injury. These sores can present as lesions, swelling, a patch of red skin, or may be open and ulcer-like. The sores are most commonly found below the knee or elbow or occasionally on the stomach or face. Usually, this will cause localised hair loss and the dog will begin licking the wound. These lesions will be followed – between two and seven days later – with outward symptoms of kidney failure: reduced appetite, fatigue, and vomiting. 
Nasal cancer makes up one to two percent of all types of tumors in dogs. Adenocarcinoma is the most common type, followed by sarcomas such as fiborsarcoma and chondrosarcoma. Signs include sneezing and bloody nasal discharge.[161]
