How to Treat and Prevent Lyme Disease in Dogs
Lyme disease in dogs is transmitted by tick bites carrying Borrelia burgdorferi. Prevention focuses on avoiding tick exposure and regular parasite control, while treatment relies on veterinary diagnosis and a course of antibiotics.
Canine and Feline Lymphosarcoma
Lymphosarcoma is a malignant cancer of the lymph nodes and lymphoid tissue that affects both dogs and cats, most often dogs over four years of age. It presents in multicentric, alimentary, and thymic forms, each with distinct clinical signs. While incurable, prompt chemotherapy can extend life from a matter of weeks to 6–24 months.
Osteosarcomas in Dogs and Cats
Osteosarcoma is a malignant bone tumor from abnormal osteoblasts, most common in large and giant dog breeds. The main sign is lameness, with swelling, pain, and possible pathological fracture. Early limb amputation plus anti-cancer medication is standard, but the outlook is poor.
Mammary Tumors in Dogs and Cats
Mammary tumors are common in intact female dogs and are the third most common feline tumor. They often appear as firm nodules in the mammary chain and can ulcerate or spread to lymph nodes and lungs. Early spaying sharply lowers risk, and surgery is the main treatment.
Cutaneous Mast Cell Tumors in Dogs and Cats
Cutaneous mast cell tumors can appear anywhere on the skin or internal organs, most often on the hind legs, perineum, and prepuce. They vary from slow soft lumps to fast hard nodules and may ulcerate. Surgical removal of well-defined tumors is the main treatment.
Melanomas in Dogs and Cats
Melanomas are pigmented tumors that may be benign or malignant, often in dark-skinned dogs such as Cocker Spaniels and Scottish Terriers. They favor the mouth, eyes, rectum, and perineum, with mucosal sites most at risk. Wide removal is used, but malignant forms carry a poor outlook.
Squamous Cell Carcinoma in Dogs and Cats
Squamous cell carcinoma is a skin tumor of the epidermal layer linked to long-term sun exposure and other skin irritation. It is the second most common skin tumor in cats and favors the head, ears, lips, and nose. Wide surgical removal is the main treatment, though it often recurs.
Penile and Preputial Tumors in Dogs and Cats
Tumors of the penis and prepuce are uncommon and, when reported, have been seen only in dogs. Types include papilloma, transmissible venereal tumor, squamous cell carcinoma, fibroma, lymphosarcoma, and hemangioma. Growths may ulcerate, bleed, and produce a foul discharge.
Prostatic Tumors in Dogs and Cats
Prostatic tumors occur mainly in middle-aged and older dogs and mimic benign prostatic conditions. Adenocarcinoma is the most serious type and can spread to local lymph nodes, spine, and pelvis. Signs include weight loss, thirst, back pain, and difficulty urinating.
Eosinophilic Myositis in Dogs
Eosinophilic myositis is a recurrent inflammation of the chewing muscles in dogs (often young herding breeds), marked by sudden swelling, eye protrusion, and trouble opening the mouth. It is likely allergic or autoimmune. Anti-allergy and anti-inflammatory care, plus feeding support, are key.
