Tapeworms* are also common and in the dog are usually Dipylidium caninum, which is spread by ingesting fleas and lice. Also common is Taenia pisiformis, spread by ingesting rabbits and rodents. Rare tapeworm infections are caused by species of the genera Echinococcus, Mesocestoides, and Spirometra. There are usually no symptoms.

Cushing’s syndrome, also known as hyperadrenocorticism, is characterized by an increase in glucocorticoids secreted by the adrenal glands. About 85 percent of cases are caused by a tumor in the pituitary gland, while 15 percent are caused by an adrenal tumor. The pituitary gland produces a hormone that signals the adrenal gland to produce cortisol; a tumor can cause it to produce the adrenal-stimulating hormone even when it is not needed. Signs include increased appetite, increased drinking and urination, a pot-bellied appearance, muscle weakness, and lethargy. Cushing’s can be caused by overuse of steroid medications; in some cases, stopping the medication is enough to solve the problem. Diagnosis can be difficult as there are no tests with both high sensitivity and specificity. Treatments inclulde mitotane, trilostane, ketoconazole, or selegiline. Surgery is used in some cases of adrenal tumors.
Pancreatitis*, or inflammation of the pancreas, is common in dogs. It is most commonly seen in middle-aged and older overweight dogs. Miniature Schnauzers are predisposed. Contributing factors include diabetes, hyperlipidemia, obesity, and dietary indiscretion. Signs include vomiting, diarrhea, abdominal pain, lethargy, and anorexia.

Sudden acquired retinal degeneration (SARD) is a disease in dogs causing sudden blindness. It can occur in any breed. The cause is unknown, but possibly involves either autoimmune disease, a toxin, or Cushing’s disease. Symptoms include sudden permanent blindness, dilated pupils, and loss of the pupillary light reflex.
What to look for: Thankfully, rabies is not as common today as it once was due to the development of vaccinations, but it is still possible for your dog to become infected with rabies even if he has received his shots. Symptoms of rabies include heavy, thick drool and aggressive behavior.
Back pain* in dogs, particularly in long-backed breeds, such as Basset Hounds and Dachshunds, is usually caused by intervertebral disk disease. It is caused by degeneration and protrusion of the disk and compression of the spinal cord. It occurs most commonly in the cervical and thoracolumbar regions. Signs include back pain, hind limb weakness, and paralysis.
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.
Some diseases and other health problems are common to both humans and dogs; others are unique to dogs and other animals. Dogs are susceptible to various diseases; similarly to humans, they can have diabetes, epilepsy, cancer, or arthritis.
Tick paralysis* is a disease in dogs caused by a neurotoxin found in the saliva of female ticks. Dermacentor species predominate as a cause in North America, while Ixodes mainly causes the disease in Australia. There is a gradual onset of signs, which include incoordination progressing to paralysis, changed voice, and difficulty eating.
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.
My dog will all the sudden get a burst of energy and run so fast he can’t stop and he will run right into things. Now he does this exorcist thing with his head, turning it back violently, teeth chattering and trying to bite his ear kind of thing and will not let anyone near him at all. I think he is having seizures but I’m not sure. I need help. Anyone??
As a dog parent, it is important to recognize the signs and symptoms of common illnesses so you can seek veterinary help for your canine friend as soon as possible. Read on for information about diseases and other medical inflictions that frequently impact dogs.
Eye diseases are common in dogs. Cataracts, canine glaucoma, and entropion are seen in dogs. Canine-specific eye diseases include progressive retinal atrophy, Collie eye anomaly, sudden acquired retinal degeneration, and cherry eye. Injury to the eye can result in corneal ulcers.
Retinal detachment* is caused in dogs by genetic disorders such as retinal dysplasia or Collie eye anomaly, trauma, inflammation or cancer. Reattachment may occur spontaneously or with medical or surgical therapy.
Does your dog wolf his food down in a blink of an eye? Then he may be at risk of bloat, which is basically an enlarged stomach; this can become even more complicated if the stomach also turns. This prevents fluid and air from escaping the stomach, which prevents the dog from belching or vomiting.

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.
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 (*).
Antifreeze (ethylene glycol), due to its sweet taste, poses an extreme danger of poisoning to dogs and cats if ingested. Even a very small amount such as a tablespoon can easily prove fatal. The antifreeze itself is not toxic, but is metabolized via the liver to the toxins glycolate and oxalate, which cause intoxication and vomiting, metabolic acidosis, and finally acute kidney failure leading to seizures and death. By the time clinical signs are observed, the kidneys are usually too damaged for the dog to survive so acting quickly is important. Immediate treatments include inducing vomiting by using apomorphine or dilute hydrogen peroxide solution (if this can be done shortly after ingestion), but these merely reduce the amount absorbed – immediate veterinary treatment is still usually imperative due to the high toxicity of the compound. Medical treatments may include fomepizole (preferred treatment) which competes favorably with the toxin in the body, ethanol which competes favorably in the liver long enough to allow excretion to take place, activated charcoal to further reduce uptake of undigested product, and hemodialysis to remove toxins from the blood. Dogs should not be allowed access to any place in which an antifreeze leak or spill has happened until the spill is completely cleaned out. Some brands of antifreeze contain propylene glycol instead of ethylene glycol and are marketed as being less harmful or less attractive to animals.
Important: if your dog is sick, do not hesitate to contact your veterinarian immediately! Your vet is skilled at properly caring for your dog. DogHealth.com is not a replacement for care by a veterinarian. It is only a resource for you to learn more about your dog’s health.
4. Parvovirus: Commonly called “parvo,” this virus is terribly common in parts of the country with low vaccination rates and can be seen in cats and dogs (although the disease cannot be spread cross-species). Parvo is most frequently seen in puppies and kittens who have not yet been vaccinated. The mortality rate depends on how quickly the symptomsare caught by the owner and addressed by a veterinarian and the strength of a pet’s immune system. Most survivors of parvovirus do not harbor long-term effects.
