Lymphatic tumors are rare in pets. Lymphangiomas are benign and lymphangiosarcomas are malignant and have a moderate-to-high metastatic potential. Patients with lymphatic tumors typically have severe edema or cavity effusions because of lymphatic obstruction and leakage. These types of tumors occur more frequently in young dogs and cats. Treatment usually involves surgical excision and chemotherapy may be used as a follow-up treatment in the case of lymphangiosarcomas.

Lymphocytic plasmacytic gastroenteritis is a form of inflammatory bowel disease. While the exact cause is not known, it is possible that the intestinal bacteria themselves may be involved in stimulating the immune response. Treatment may include nutrition management, immunosuppressive medications, and dietary supplementation of cobalamin, prebiotics, and probiotics.

Lymphoma is a cancer of the lymph nodes and lymphatic system. This cancer may be localized to one particular region, or may spread throughout the entire body. Lymphoma is a relatively common cancer, accounting for 15-20% of new cancer diagnoses in dogs. The prognosis for lymphoma varies, depending on various characteristics that can only be determined by specialized testing.

The most common forms of cutaneous lymphoma are epitheliotropic lymphoma and dermal lymphoma. No specific risk factors or causes have been identified in the development of cutaneous lymphoma. Generally, cutaneous lymphoma can appear as various-sized irritated, ulcerated, or infected patches anywhere on the skin, including the gums, nose, or lip margins. These areas may become ulcerated and bleed, or become crusted. Secondary infections are possible. By far, the most common treatment for cutaneous lymphoma is chemotherapy. Unfortunately, the response to treatment, although initially encouraging, is typically short-lived, with gradual return of the tumors.

Lysosomal storage diseases are a rare collection of conditions that are inherited. Many of them are more prevalent in certain breeds and are seen in the first few months of life. Clinical signs vary depending on the type of disease, but commonly include failure to thrive, incoordination, vision loss, and seizure. Prognosis is usually poor for long-term survival.

Early decontamination including induction of vomiting and activated charcoal administration can be performed by your veterinarian to recover and prevent absorption of macadamia nuts if ingestion is discovered prior to onset of clinical signs. Supportive therapies are provided for symptomatic dogs including intravenous (IV) fluids, pain relievers, muscle relaxants, and anti-nausea medications. Dogs with mild clinical signs can be treated without hospitalization.

Once a pet has lost some weight, the new goal is to make sure that excess weight stays off. Pet parents who partner with their veterinary health care team for support and who focus on changing their behaviors often have the most success. Examples of some changes include using a different food or a different feeding method, focusing more on portion control, and incorporating some movement or activity time into each day. This article addresses several commonly asked questions about how to help a pet during the maintenance phase (after the weight has been lost).

Bacterial overgrowth is a condition of the small intestine resulting in increased numbers of bowel bacteria. The major concern with bacterial overgrowth is the development of a condition called small intestinal bacterial overgrowth. The bacteria cause damage to the surface of the bowel so digested food cannot be absorbed resulting in malabsorption of nutrients. Malabsorption and SIBO both result in diarrhea but with bacterial overgrowth the diarrhea is chronic. Many cases respond to long term antibiotics.

There are several different types of malignant mammary tumors, with carcinomas being the most common. Carcinomas arise from epithelial (skin) cells, tubules of the mammary glands, or other cells found in the mammary chain. The size of the masses and their appearance may vary, but they are usually firm and nodular. Occasionally, the skin over the mass may ulcerate (open) and bleed, and the affected area may feel warm to the touch and become painful. Detecting and treating these tumors when they are small, and before spread has occurred, will provide your dog with the best chance for long-term control.

Dogs have four types of teeth: incisors, canines, premolars, and molars. Skeletal malocclusion results when an abnormal jaw length creates a malalignment of the teeth. Dental malocclusion occurs when the upper and lower jaw lengths are considered normal but one or more teeth are out of normal alignment. This article explains the common forms of skeletal and dental malocclusion seen in dogs.
