The uropygial gland (preen/preening gland or oil gland) is a normal part of most bird's anatomy. The preen oil is formed by the gland and helps coat a bird's feathers. Infections and tumors may affect the uropygial gland.

Every dog has wants and needs, including social interaction, physical exercise, intellectual exercise, and time to rest. When their needs are met predictably and enrichment is consistently available, dogs experience less stress and frustration and may be less likely to develop problematic behaviors.

Predictability and trust are important foundations for training your dog. Learning what your dog finds rewarding and strategically providing rewards at the right time will promote the desired behavior to happen more and more often. Punishment techniques using physical force and conflict can result in increased aggression and should be avoided.

Uterine tumors are quite rare in North American pets, mainly due to routine spaying practices. Several types of tumors can arise from the tissues of the uterus. This handout discusses uterine tumors in dogs and cats. The various types of these tumors, along with the clinical signs, diagnosis, treatment, and prevention of this condition are outlined.

There are six primary reasons for vaccination failure. Vaccine inactivation is one reason and is most commonly caused by warming during shipping and handling. In addition, vaccines are not always 100% effective. Dogs may also be unhealthy or too young, leading to vaccine failure. Interference by maternal antibodies can lead to the vaccine being blocked.

Vaginitis refers to inflammation of the vagina and can be a result of several possible underlying causes. Prognosis is generally good, especially if the underlying cause is identified and treated early. The most common clinical signs of vaginitis include increased frequency of urination, licking of the vaginal area, vaginal discharges, and scooting or rubbing of the vaginal area. Diagnostic testing to determine the cause of a dog's condition is helpful in identifying the appropriate antibiotic treatment.

Vascular tumors of the skin develop from the blood vessels of the skin. These tumors may arise anywhere on the body and appear as a firm and raised lump on or under the skin. Hemangiomas may ulcerate and bleed; hemangiosarcomas may bleed into the surrounding tissues. This type of tumor is typically diagnosed via a tissue biopsy or surgical removal of the entire tumor. Surgery is the recommended treatment for vascular tumors of the skin.

The physical examination is a crucial part of assessing the health of a new pet bird. Avian veterinarians may perform special test along with a complete physical examination to determine the bird's true health status. The visit should also include a thorough discussion of proper nutrition, housing, care, grooming and training/socialization of your new bird.

Testing for FeLV is recommended to detect underlying causes to illness, to screen apparently healthy cats who may have been exposed to the viruses, and to identify carriers of the viruses prior to introducing cats into a household of other cats. Testing protocols are discussed. Vaccination against FeLV will not affect the outcome of a cat already infected with the virus nor will it affect testing.

Visceral vascular tumors are tumors which arise from blood vessels. The main tumor types are hemangiosarcomas (cancerous) and hemangiomas (benign). The clinical signs vary depending on the location of the tumor. Surgery is the recommended treatment option. Given the highly metastatic nature of hemangiosarcoma, chemotherapy is also recommended.
