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.

Total ear canal ablation and bulla osteotomy (TECA-BO) is a surgery performed to remove the ear canal and a portion of the middle ear. This surgery is performed in cases where the pet is suffering from chronic and unresponsive ear infections. The surgical technique, reasons for performing the procedure, the diagnostic steps, and potential post-op complications are outlined in this handout.

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.

Transdermal means the application of a medicine or drug through the skin, where it is absorbed into the bloodstream. Relatively few drugs are currently available for transdermal application. The biggest risk with a transdermal medication is that it could be insufficiently absorbed, resulting in inadequate drug levels and treatment. The inside of the outer ear flap (not inside the ear canal) is an excellent area to apply transdermal medications. After you have administered the medication, try to distract your pet from scratching or rubbing the ear for a few minutes by feeding your pet, taking your pet for a walk, or playing together immediately afterward. If your pet is prescribed a transdermal medication patch, your veterinarian will often shave an area to affix the patch.

Transmissible venereal tumors (TVTs), often found in genital areas, are spread through contact with other dogs, most often sexual contact. The tumors are usually cauliflower-like in appearance. Diagnosis and treatment is discussed.

Your dog has allergies. These instructions have been provided by your veterinary healthcare team to help you treat your dog for his specific allergy. The instructions that relate to your dog are checked.

Trifluridine is an antiviral topical medication used to treat viral infections of the eye, such as herpesvirus-1 in cats. Give as directed. Side effects include eye irritation. Do not use in pets with an allergy to this medication. If a negative reaction occurs, please call the veterinary office.

Trypsin-like immunoreactivity (TLI) is a blood test that measures the amount of a pancreatic proenzyme called trypsinogen. This measurement correlates with the amount of pancreatic enzymes released into the intestine to aid in digestion. A low measurement indicates exocrine pancreatic insufficiency. Concurrent pancreatitis or tests done shortly after a meal may temporarily increase this measurement to a normal value (false negative).

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.

Ultrasound uses the reflection of sound waves to generate an image of internal structures allowing for identification of masses, pregnancy diagnosis, abnormal heart function and muscle size, abnormalities of the orbit, and abnormal appearance of abdominal organs. It cannot be used to identify abnormalities in areas of air such as the lungs, or areas surrounded by bone. B-Mode generates a 2-dimensional image, while M-Mode can be used to trace structures in motion and is often used in ultrasound evaluation of the heart. Doppler can be used to identify speed and direction of fluid flow such as blood flow. Anesthesia is generally not needed unless tissue biopsies are planned. Shaving of fur is recommended to allow best contact of the probe with the skin to produce the most diagnostic images. Ultrasound results can be analyzed in real time; however, assessment by a radiologist may take several days. Ultrasound is an invaluable tool to detect problems in a non-invasive fashion.
