  • Heatstroke is another term for hyperthermia. Dogs suffering from heatstroke can have varied signs, from high respiratory rate to coma, depending on their temperature. Prognosis depends on the extent and duration of temperature elevation. Some dogs recover normally, but more severe cases will have permanent organ damage or may die from hyperthermia.

  • Phobias related to thunderstorms and fireworks cause dogs to suffer and often increase in intensity over time. Behavior modification combined with medication can be used to reduce a dog's level of fear. Until therapy can be completed, it can be helpful to sit with your dog in a safe room where background music and curtains can be used to help buffer noises and flashing lights.

  • Your older dog requires more care and attention to make sure they have the best quality of life. If they have certain medical conditions, that will factor into what they can do and how often they may need to see your family veterinarian. It's important to spend time with your dog not only for social interaction but to stimulate their mind.

  • Osteoarthritis (OA) is a progressive, degenerative disease that worsens over time. This handout discusses steps you can take to help your dog deal with osteoarthritis (OA) or degenerative joint disease (DJD). In addition to medications that may be prescribed by your veterinarian, other treatment options such as weight loss, exercise, and complementary therapies such as chiropractic and physiotherapy are outlined.

  • An aural hematoma is a collection of blood between the cartilage and skin of the ear flap. It is most usually caused by trauma but can also be due to a bleeding disorder. Hematomas in dogs can be treated in different ways but should be treated early to minimize pain and disfigurement. If an underlying cause is determined such as otitis externa, this needs to be treated as well. Hematomas may eventually resolve on their own, but there is a risk of cauliflower ear and they are painful, so prompt treatment is recommended.

  • Hemophilia A and B are clotting disorders involving a deficiency of a specific clotting factor (A: Factor VIII, B: Factor IX) needed for appropriate homeostasis. They are caused by a sex-linked recessive genetic mutation. Affected dogs will show inappropriate hemorrhage including bruising, lameness induced by bleeding into joints and body cavity hemorrhage. It can be diagnosed with a slow APTT and demonstrating low levels of the factor involved. Hemophilia A is more common than B and is generally, more severe. Because it is sex-linked recessive, males are more likely to be affected than females but females still act as carriers, so genetic screening is important prior to breeding to prevent this disease.

  • Hepatic encephalopathy is a neurologic condition in cats and dogs that is caused by an underlying liver condition. It can cause lethargy, seizures, problems with balance and coordination, and coma. Common causes, methods to diagnose the condition, and its treatment options are explained in this handout.

  • This handout explains hepatic microvascular dysplasia, a condition where microscopic blood vessels within the liver are underdeveloped or absent, resulting in decreased blood flow to the liver. As a result, the liver is less capable of dealing with toxins or producing the vital proteins needed for good health. Methods to diagnose the condition and its treatment options are also explained.

  • Hepatoid gland tumors are a type of cancer that develop from the sebaceous (sweat) glands of the skin. The most common location for these tumors to develop is the perianal area, and the most common tumor is the perianal adenoma. Perianal adenocarcinomas, and rarely perianal epitheliomas may also occur. These tumors appear as one or more small, round, pink, hairless, slow-growing nodules around the anus, and can sometimes ulcerate and become infected. Malignant tumors can grow much bigger and faster, invade the underlying tissue, and metastasize. Diagnosis may be made by fine needle aspiration, biopsy, or full excision of the tumor. Staging is recommended for adenocarcinomas. Treatment may involve surgical removal along with neutering, cryotherapy, laser ablation, radiotherapy, chemotherapy, and occasionally hormone therapy. The prognosis is good with perianal adenomas, fair to poor with adenocarcinomas, and generally good with epitheliomas.

  • Hepatozoonosis in dogs is caused by ingestion of one of two organisms: H. americanum and H. canis. Both parasites are more common in the southern United States. The clinical sign and treatments for dogs with hepatozoonosis differ depending on the parasite species causing the infection. In either case, with appropriate treatment, the prognosis is generally good.
