Systemic lymphoma is a very common cancer in dogs, but the cutaneous form is quite rare. Current statistics suggest that cutaneous lymphoma accounts for only about 5% of canine lymphoma cases. The disease can present in a variety of lesions, including ulcers, nodules, red patches, and areas of hair loss and skin scaling. Because not very much is known about canine cutaneous lymphoma, there are no standard treatment protocols and the prognosis is poor.

Cuterebra are botflies that spend the larvae stage of their lifecycle within rodent or rabbit hosts and can accidentally infect dogs. They enter through the nose, mouth or a skin wound. They usually develop a cyst under the skin that can be located as it enlarges and often a breathing hole can be seen. The larva (warble) will leave the dog when it is ready to form a pupa but it will often leave behind a secondary bacterial skin infection or abscess in the empty cyst. Rarely, the larva/cuterebra migrate aberrantly through the dog causing inflammation and damage to different tissues, including the brain and eyes, and even potentially cause a severe systemic inflammatory response. Treatment depends on what damage has been done and can include removal of the warble, debridement or removal of the cyst, antibiotics and symptomatic and supportive treatment of the results of aberrant migration. Prognosis is generally good if only the skin is involved. Cuterebra infection can not be prevented easily, so monitoring the dog regularly for signs is important.

Cysts are hollow spaces within tissues that contain either a liquid or a solidified material. Some breeds have a tendency to develop certain types of cysts. Accurate diagnosis relies upon microscopic examination of a piece of tissue. The most common treatment for cysts is surgical removal. It is important to prevent your pet from rubbing, scratching, or otherwise bothering the cysts or the surgical site.

Cytology is a useful tool to often diagnose abnormal lumps on your pet's body as well as evaluation of fluid samples and tissue surfaces. It is relatively simple and inexpensive but can provide a lot of information. Depending on results, further tests may be indicated to best help your pet.

Cytology is the microscopic examination of cells that have been collected from the body. Lesions on the surface of the skin or from moist body cavities can be sampled very simply by scraping, swabbing, flushing, or making impressions of the tissue. The collected cells get looked at under a microscope and in many cases a diagnosis can be made to determine the best form of treatment.
-
Collecting tissue samples for cytology or histopathology allow a pathologist to often give a diagnosis of the type of mass or tumor your pet has. Samples can be obtained by fine needle aspirate or biopsy, where a piece of the mass is cut out. Based on what the mass appears like under the microscope, the pathologist can often give a prognosis of how the tumor will behave.

Dog food labels can certainly be confusing to interpret. In the United States, the Association of American Feed Control Officials (AAFCO) has developed model laws and regulations that states use for animal feeds. In Canada, pet food labeling guidelines are regulated by the Consumer Packaging and Labeling Act administered by Industry Canada. The Canadian government's Competition Bureau also has an extensive working group that upholds a voluntary code of conduct for the labeling and advertising of pet food. The most important information when comparing one dog food to another is the guaranteed analysis. Ingredient lists are somewhat useful when evaluating a particular dog food, but it is important to recognize the limitations. Talk to you veterinarian about the ingredient list and nutrient profile to help choose the diet that is right for your dog.

Your veterinarian wants to keep your pet healthy and the fact is that people who are better informed take better care of their pets. Do not be overwhelmed by “medicalese”. Try your best to understand this foreign language and if you cannot quite decipher it, ask your veterinarian to speak more plainly.

This handout describes and illustrates this condition, and discusses the causes, clinical signs, diagnosis, and treatment options for degenerative disc disease in dogs. Surgical intervention is specifically outlined and rule-outs for other conditions causing similar signs are also discussed.

Degenerative joint disease is arthritis caused by deterioration and degeneration of tissues lining joints. Treatment includes regular gentle exercise, anti-inflammatory drugs and other medications, omega fatty acids, chondroprotectants, and possibly other nutraceuticals. Emerging therapies include rehabilitation therapy, acupuncture, and stem cell or platelet rich plasma therapies. Maintaining your dog’s weight can help prevent degenerative joint disease.
