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.

The most common cause of hip dislocation is blunt force trauma such as a fall or an automobile injury. Most dogs with a hip dislocation will have severe hind limb lameness and pain and may not be able to put any weight on the affected limb. A diagnostic radiograph will show the direction of dislocation and whether a fracture of any part of the hip joint has occurred. In many cases, it is possible to replace the femoral head in the acetabulum by manipulation under general anesthesia. If the femoral head has been successfully replaced and the correct post-operative treatment has been adhered to, it is unlikely that the hip will dislocate again.

An increase in your pet’s breathing rate while resting quietly or sleeping is an early clinical sign that your pet may be developing heart failure and needs to see your veterinarian. In general, all normal dogs and cats have a breathing rate of between 15-30 breaths per minute when they are resting. Resting breathing rates that are consistently greater than 30 breaths per minute are increased and considered abnormal. One breath is counted when the chest has moved in and out once. Typically, your veterinarian will have you count the breathing rate once per day for a week while you are learning and then will set up a schedule depending on your pet’s heart health status.

Home renovation can be arduous for every member of the household. Both pet owners and pets can be stressed during the construction process. Pets are faced with many potential hazards in a construction site. Pets can also interfere with construction workers and pose a safety risk to them. Awareness of possible construction site problems will help home owners avoid pet-related issues. Knowing how to deal with problems that do occur will minimize health risks for pets. A little planning can make the renovation process run more smoothly for workers, home owners, and pets.

Birds are naturally mischievous and if not properly supervised, will get into many predicaments. It is crucial that you bird proof your home. The bird's cage is its house and the confines of your home represent the bird's environment.

Mini-pigs may be housed successfully inside if they are given enough space, an area in which to root, and proper environmental enrichment. Ideally pet pigs should have access to a safe area of untreated lawn outside in which to root and chew on grass. Pet pigs generally like to urinate and defecate in a single area that is far from where they eat and sleep and can be trained to eliminate either inside and outside. Pigs in urban environments may be taught to walk on a leash/harness and go outside like dogs. If this is not feasible, they can be trained to use a litter pan indoors.
