Dog hookworms are tiny worms that can spread through contact with contaminated soil or sand. Dogs can also become infected with hookworms through accidentally ingesting the parasite from the environment or through their mother’s milk or colostrum. Young puppies are most often affected and might have dark, bloody stool and anemia. Severe infections in some puppies can lead to death.

8. Arthritis: Arthritis is often seen as a rite of passage for our older pets. They may seem slow to rise in the morning, or a bit reluctant to jump up to their favorite spot on the couch. Your veterinarian can diagnose most forms of arthritis during a routine exam, but they may also recommend an x-ray to rule out other issues or evaluate how seriously inflamed the joints are. While there is no cure for arthritis, there are joint supplements, and even treatments like acupuncture, to help keep your pet as mobile as possible for as long as possible.
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.
Genetics and environmental factors also play a role in cancer development. Some credit the uptick in canine cancer rates to dogs simply living longer with better health care options. Other blame dog “junk” food for the rise, with brand-name foods using ingredients thought to cause cancer. Check the labels and avoid BHT, BHA, and ethoxyquin.
Toxocara roundworms cause a parasitic disease known as toxocariasis. Dogs and people can become infected by accidentally swallowing roundworm eggs from the environment. In addition, larval worms can cross through the placenta, milk, or colostrum of a mother dog, passing the infection to her puppies. Infected puppies usually do not develop and grow well and might have a pot-bellied appearance.
Bloat can affect any dog at any age but there are breeds more susceptible to it: usually large breed, deep-chested dogs like Great Danes, German shepherds, boxers, Labrador retrievers, bloodhounds, and weimaraners. Mid-size and smaller dogs aren’t much at risk, with the exception of basset hounds and dachshunds, who also have long, broad chests.
Vogt-Koyanagi-Harada syndrome is a condition seen in dogs characterized by uveitis (inflammation of the inside of the eye), poliosis (whitening of hair), and vitiligo (loss of pigment in the skin).
Infected people will typically have a red “bull’s eye” rash at the site of the tick bite that appears about 7 days after being bitten. Flu-like symptoms quickly follow the rash. If not treated, this disease can spread to other parts of the body and cause symptoms such as arthritis and loss of facial muscle tone (Bell’s palsy). Lyme disease can be fatal.

How to treat: Again, assess the behavior leading up to the vomiting. If there was nothing unusual, then there’s probably no need to be concerned. If the vomiting is persistent, however, or you noticed your dog acting differently before the vomiting, there could be a number of things wrong and it’s best to take your dog to your vet to get him checked out.
Food allergy* in dogs is commonly manifested as itching, especially of the face, paws, and the underside. Skin testing has proved unreliable, and a trial of a hypoallergenic diet is usually used for diagnosis.
Babesiosis* is spread by members of the family Ixodidae, or hard ticks. The two species of the genus Babesia that affect dogs are B. canis and B. gibsoni. Babesiosis can cause hemolytic anemia in dogs.
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.

Diabetes insipidus* in dogs can be central, caused by a lack of antidiuretic hormone (ADH), or nephrogenic, caused by a lack of response of the kidneys to ADH. Neither form is common. Central diabetes insipidus (CDI) is usually idiopathic, but can also be caused by head trauma or tumors of the brain. Nephrogenic diabetes insipidus (NDI) can be primary (hereditary) or secondary (caused by a variety of metabolic and renal diseases, including Cushing’s syndrome and pyometra). Because the disease is characterized by an inability to concentrate urine, the most common sign is increased drinking and urinating. Treatment of CDI is to use desmopressin, a synthetic analog of ADH. Treatment of NDI is to treat the underlying cause, if any.
My 13 yr old male miniature (24lb) neutered Dachshund has started to urinate when at rest. Usually at night, other than that he is acting normal & eating well. He does drink a lot but not really any more than what he has normally consumed before this all started. We are waiting for the results of his urinalysis. Any suggestions out there?
Coccidioidomycosis* is a fungal disease caused by Coccidioides immitis or Coccidioides posadasii that affects a variety of species, including dogs. In dogs signs of primary pulmonary disease include a cough, fever, weight loss, anorexia, and lethargy. Disseminated disease occurs when the fungus has spread outside of the lungs and may include clinical signs such as lameness, pain, seizures, anterior uveitis, and localized swelling. Diagnosis of Valley Fever may include multiple tests, including serology and radiology. According to a study performed in the Tucson and Phoenix area, 28% of dogs will test positive for exposure to the fungus by two years of age, but only 6% of the dogs will be ill with clinical disease. There is an increased risk of infection associated with amount of time spent outdoors, a larger roaming space accessed by the dog, and increasing age.
Pulmonic stenosis* is a congenital heart disease in dogs characterized by right ventricular outflow tract obstruction. Most commonly the narrowing occurs at the pulmonary valve but it can also occur below the valve (subvalvular) or above the valve (supravalvular). The most commonly affected breeds include terriers, Bulldogs, Miniature Schnauzers, Chihuahuas, Samoyeds, Beagles, Keeshonds, Mastiffs, and Bullmastiffs. Signs may include exercise intolerance, but often there is only a heart murmur.

Vaccine reactions are adverse events which occur following vaccination, including granuloma formation, but most commonly the term vaccine reaction is used to describe a type I hypersensitivity reaction. The most common signs are facial swelling and hives, but more rarely very serious signs such as hypotension and collapse may occur.
Hemorrhagic gastroenteritis is a disease of dogs characterized by sudden vomiting and bloody diarrhea. The symptoms are usually severe and can be fatal if not treated. It is most common in young adult dogs of any breed, but especially small dogs such as the Toy Poodle and Miniature Schnauzer.
Retinal dysplasia is an eye disease affecting the retina. It is usually a nonprogressive disease and can be caused by viral infections, drugs, vitamin A deficiency, or genetics. Retinal dysplasia is characterized by folds or rosettes (round clumps) of the retinal tissue.
Salmon poisoning disease is a fatal disease caused by infection with a rickettsia, either Neorickettsia helminthoeca or Neorickettsia elokominica. Dogs are infected by eating raw salmon from the Pacific Northwest.
Leptospirosis is a zoonotic disease caused by bacteria of the genus Leptospira. Humans and dogs become infected through contact with water, food, or soil containing urine from infected animals. This may happen by swallowing contaminated food or water or through skin contact, especially with mucosal surfaces, such as the eyes or nose, or with broken skin. In dogs, transmission most commonly occurs by drinking puddle, pond, or ditch water contaminated by urine from infected wildlife such as squirrels or raccoons. The liver and kidney are most commonly damaged by leptospirosis. Vasculitis can occur, causing edema and potentially disseminated intravascular coagulation (DIC). Myocarditis, pericarditis, meningitis, and uveitis are also possible sequelae.
Ticks* are an external parasite of the dog and can spread diseases such as Lyme disease, Rocky Mountain spotted fever, babesiosis, and ehrlichiosis. They can also cause a neurological disorder known as tick paralysis.
Tick-borne diseases are common in dogs. Lyme disease, or borreliosis, is caused by Borrelia burgdorferi and spread by Ixodes pacificus on the West coast of the United States and by I. scapularis (deer tick) in the rest of the U.S. Signs and symptoms include fever, joint swelling and pain, lameness, and swelling of the lymph nodes. It has been diagnosed in dogs in all 48 states of the continental U.S. Ehrlichia canis, which causes canine ehrlichiosis, and Rickettsia rickettsii, which causes Rocky Mountain spotted fever, are both spread by the American dog tick, Dermacentor variabilis, and the brown dog tick, Rhipicephalus sanguineous.
Wash your hands with soap and running water after contact with dogs, dog saliva, or dog stool. Be sure to assist children with handwashing. Thoroughly washing hands will reduce the risk of disease transmission to people.
Collie eye anomaly (CEA) is a congenital, inherited, bilateral eye disease of dogs involving the retina, choroid, and sclera. It can be a mild disease or cause blindness. It is known to occur in Smooth and Rough Collies, Shetland Sheepdogs, Australian Shepherds, Border Collies, and Nova Scotia Duck Tolling Retrievers.
This list of dog diseases is a selection of diseases and other conditions found in the dog. Some of these diseases are unique to dogs or closely related species, while others are found in other animals, including humans. Not all of the articles listed here contain information specific to dogs. Articles with non-dog information are marked with an asterisk (*).
Pericardial effusion* is a collection of fluid in the pericardium. It is usually serosanguinous (bloody fluid). Serosanguinous accumulation can be caused by cancer, usually hemangiosarcoma or a heart base tumor, idiopathic pericarditis. Rare causes include trauma, clotting disorders, and left atrial rupture. Serous accumulation is rare and caused by heart failure, peritoneopericardial diaphragmatic hernias, uremia, pericardial cysts, or hypoalbuminemia. Rarely pericardial effusion can be caused by infection and consist of pus. An echocardiogram should be done prior to draining the fluid, if possible, to identify the cause (e.g., tumor). Drainage of the fluid (pericardiocentesis) relieves the clinical signs and, in the case of idiopathic pericarditis, can be curative.
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. It is more common in smaller breeds of dogs

Hereditary orthopedic diseases are mainly found in purebred dogs. Hip dysplasia is a common problem that primarily affects larger breeds. Hip dysplasia is a defect in the shape of the hip joint which can, depending on the degree of hip luxation, be quite painful to the dog as it ages. Over time it often causes arthritis in the hips. Dysplasia can also occur in the elbow joint. Luxating patellas can be a problem for smaller breeds. It can cause lameness and pain in the hind legs.
“Anytime you’re out with your dog,” says Pat Miller, author of The Power of Positive Dog Training, “one of you is training the other.” Better for it to be you. Begin as early as 8 weeks, before it picks up bad behaviors, and continue even into old age to keep your dog sharp. Make training about reward, not punishment. (Old-school devices like choke collars injure and instill fear, Miller says, “the most common cause of canine aggression.”) When housebreaking, “keep your puppy under close supervision and take it outside more often than he needs to go,” says Miller. “Reward it when it goes to the bathroom so it learns that this is the right way to do it.” Tip: “A well-trained dog has more opportunities to improve its physical health,” Miller adds. Walks, fetch, and agility training are more fun for you both if your dog will come when called, wait when asked, and greet other people and pups politely.

It takes just three weeks for one flea to turn into an infestation of 1,000 biting bugs. A very common canine health problem, fleas are easy for your dog to pick up, but they’re also easy to treat. Signs your dog may have fleas include:
Hypoadrenocorticism, also known as Addison’s disease, is a reduction of production of glucocorticoids and mineralocorticoids by the adrenal glands. There is more familiarity with the glucocortcoids, such as cortisol; mineralocorticoids control the amount of potassium, salt and water in the body. It is most commonly caused by destruction of adrenal tissue, probably by autoimmune disease. Signs include increased drinking and urination, vomiting, diarrhea, collapse, shivering and weight loss; at times neither the causes nor symptoms are especially specific. Because of this it is sometimes referred to as “the Great Mimic” or “the Great Imitator”. It is possible not to see any symptoms of the disease until the adrenal cortex is 90% dysfunctional. Addison’s can occur when regular steroid use is abruptly discontinued; during their use, the system the adrenal gland does not function at 100%. The system senses sufficient levels of these hormones in the body and does not signal for their production. Tapering the medication off gradually allows them to return to full production after discontinuation. About 35% of affected dogs are not diagnosed until they experience an Addisonian crisis, which outwardly appears to be a “classic” shock and is a medical emergency. Hyperkalemia can develop and cause severe bradycardia. Only typical Addison’s patients have the risk of Addisonian crisis due to the lack of mineralocorticoids. Treatment is with supplementation of mineralocorticoids in daily pills or a monthly injection. The atypical form and the form caused by abrupt withdrawal of steroids do not need mineralocorticoids. Glucocorticoids are usually supplemented with oral prednisone.

“The cause of Alabama Rot, clinically known as idiopathic cutaneous and renal glomerular vasculopathy (CRGV), is still unknown and there is no known way to prevent a dog from contracting the disease,” said David Walker, from Anderson Moores.
Ectropion (eyelid folding outward) is a common condition in dogs, usually affecting the lower lid. Breeds associated with ectropion include the Cocker Spaniel, the St. Bernard, the Bloodhound, and the Basset Hound.
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.
Intussusception* is characterized by telescoping of one part of the gastrointestinal tract into another part, forming an obstruction. It is most common in dogs six to eight months old. Surgery is necessary for treatment.

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.
