Dogs + Medical Conditions

  • Weakness can be caused by many different problems and can involve a variety of body systems. Finding the cause of your pet’s weakness starts with a complete history and physical examination. The most commonly recommended screening tests for weakness include complete blood count, serum biochemistry profile, urinalysis, and in a dog, total thyroxine. Additional tests may be recommended based on the results of these screening tests. 

  • Tetanus is a medical condition caused by a toxin. This toxin, produced by the bacteria Clostridium tetani, affects the nerves, spinal cord and brain, leading to hyperexcitability resulting in muscle spasms. Dogs are less susceptible to the effects of tetanus toxin than humans and horses. Tetanus is typically diagnosed based on exam findings. Dogs with tetanus require intensive nursing care. Most dogs develop localized, self-limiting disease, which will respond to appropriate early treatment.

  • Nutrition plays an essential role in treating and preventing urinary stones (uroliths). Since the diet can affect urine dilution, composition and pH, pet foods can be critical to the success or failure of treatment and prevention. Important factors are covered, such as the importance of water intake, diet composition, relative supersaturation (RSS) testing, and urinary diets.

  • Thrombocytopenia is a condition of low blood platelets, resulting in abnormal hemorrhage and possible anemia. There are many causes, including severe or prolonged blood loss, increased internal destruction of platelets, or impaired bone marrow production. Several diseases and medications are also associated with thrombocytopenia. Treatment may require the replacement of platelets along with treatment of the specific underlying cause.

  • Toad poisoning occurs when a dog is exposed to the toxins secreted by certain species of toads. The two most common species of toads that cause poisoning in the United States are the cane or marine toad and the Colorado River or Sonoran desert toad. While there are toads in Canada that secrete toxic substances, their effects are much less severe than the toxins secreted by the cane or Sonoran desert toads. Death can occur quickly and immediate treatment is required.

  • The tonsils are similar to lymph nodes, and the role of both of these structures is to fight infection. There is a pair of tonsils located in small pouches at the back of the throat that enlarge during infection or inflammation. Tonsillitis usually occurs as a result of another disease that affects the mouth or throat. If an underlying source of the infection can be found, it must be treated.

  • The trachea, or windpipe, is the tube connecting the throat to the lungs. Tracheal collapse occurs most frequently in middle-aged to senior dogs (4-14 years), but some younger dogs can also be affected. The most common clinical sign is a persistent, dry, harsh cough, sometimes referred to as a "goose honk". Pets who have surgery for the condition often need medications for life. The prognosis will depend on how well your dog responds to treatment.

  • A trichobezoar, or hairball, can form when a dog ingests hair that does not pass through the intestinal tract. When this occurs, the hairball may be vomited up uneventfully or it may lead to a gastrointestinal obstruction. If a trichobezoar causes an obstruction, surgical management is necessary.

  • Damage to the tympanic membrane and middle ear infections can be very painful for dogs and cause a variety of clinical signs affecting the skin and nervous system. Diagnosis often requires a thorough ear examination with testing while your dog is under sedation or anesthesia. The treatment methods and prognosis depend on the nature of your dog's condition.

  • The anconeal process is a small projection of bone on the ulna, the longer of the two bones of the forearm. If the anconeal process does not fuse to the rest of the ulna correctly during growth, it causes a condition called ununited anconeal process (UAP). This problem appears to be hereditary mostly in large breeds. When this part of the ulna does not fuse, the elbow joint becomes unstable, causing lameness and pain. Treatment requires surgery. Some form of rehabilitation will improve your dog's chances of making a full recovery from surgery and minimize lameness problems.
