  • Mast cell tumors are most common in the skin of dogs and have a nodular, alopecic, sometimes inflamed appearance. These can be itchy and can fluctuate in size. They are generally easily diagnosed by fine needle aspirate but histopathology is needed to grade the tumor to determine the prognosis and best management. Tumors can range from lower-grade, with minimal metastasis and spread, to higher-grade, with a high risk of metastasis and local invasion. Treatment usually involves surgical removal with wide margins and, depending on complications, may require supportive treatment including chemotherapy, radiation therapy, and therapy to target the mutation that instigated the tumor.

  • Masticatory muscle myositis (MMM) is an immune system disorder in which the dog's immune system identifies the dog's own muscle tissue as foreign and attacks it.

  • Mastiffs are mellow and many are happy just watching family ballgames from the sidelines, cheering their kids on with a wag or a woof. Some, however, might happily join in to steal the ball or play a short game.

  • Mastitis is a term used to describe inflammation of a mammary gland. In most cases, mastitis is caused by a bacterial infection. Trauma to the mammary gland, or prolonged periods of milk accumulation without milk removal, can lead to inflammation within the mammary gland. Most dogs with mastitis can be treated on an outpatient basis with oral antibiotics and pain medications, though severe cases may require hospitalization or surgery.

  • Melanomas are cancerous growths of the cells responsible for pigmentation of the skin. They can develop anywhere on the body but those on the toes carry the highest chance for malignancy. They may be painful and you may notice your pet licking at the affected area. Surgery is often the treatment of choice and may be followed up with radiation or chemotherapy.

  • Melioidosis is a bacterial infection that is typically associated with tropical regions. The bacteria that causes melioidosis, Burkholderia pseudomallei, is usually found in soil and water. The clinical signs of this condition, along with transmission, diagnosis, treatment, and prognosis, are outlined in this handout.

  • Meloxicam is given by mouth or injection and is used to treat general and surgical pain, inflammation, fever, and osteoarthritis. Side effects are uncommon but may include upset stomach, changes in urination, or yellowing of the skin. Do not use in pets that are sensitive to NSAIDs, have kidney or liver disease, are dehydrated or anorexic, or are currently taking other steroids or NSAIDs. If a negative reaction occurs, contact your veterinarian.

  • This handout discusses meningitis, an inflammation of the membranes that cover the brain and spinal cord, in dogs. The numerous potential causes, along with the diagnosis, treatment and prognosis of the condition are outlined.

  • Meningoencephalitis is a term referring to inflammation of the brain and the surrounding fluid and tissues. Meningoencephalitis of unknown origin is a term used to describe those cases of meningoencephalitis in which MRI and cerebrospinal fluid analysis indicate the disease but diagnosis through histopathological analysis is not possible. Treatment typically involves immunosuppressant drugs, sometimes with the addition of antibiotics. The prognosis depends on several factors, which are also explained in this handout.

  • Metronidazole is given by mouth and is used off-label to treat certain anaerobic bacterial and protozoal infections and gastrointestinal conditions in dogs, cats, and other animals. Give as directed. Side effects may include nausea, vomiting, diarrhea, regurgitation, decreased appetite, tiredness, and drooling. Do not use in pets that are allergic to it, are debilitated, or are pregnant or nursing. If a negative reaction occurs, contact your veterinarian.
