Skin Disease in Collies and Other Herding Breeds: Why Medication Must Be Chosen Carefully
Collies and related herding breeds often carry an MDR1 gene mutation that prevents normal drug clearance, making them dangerously sensitive to certain parasiticides such as ivermectin. Skin problems are treated as in any dog, but parasite control and other medications must be chosen with a veterinarian to avoid toxicity.
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.
Sertoli Cell Tumors in Dogs and Cats
Sertoli cell tumors are hormone-producing testicular tumors of older male dogs and cats that cause feminization through excess estrogen. Signs include symmetrical hair loss, enlarged breasts, and a lengthened prepuce. Surgical removal of both testicles resolves most signs within a few months.
Testicular Tumors in Dogs and Cats
Testicular tumors are among the more common tumors in older dogs and are rare in cats. They often cause feminization from excess estrogen, including attraction from other males and symmetrical hair loss. Surgical removal of the affected testicle is the standard treatment, and neutering prevents the disease.
Vaginal and Vestibular Tumors in Dogs and Cats
Vaginal and vestibular tumors are the second most common reproductive tract tumor in female dogs and cats, ranging from benign leiomyomas to transmissible venereal tumors. Signs include a mass protruding from the vulva, difficulty urinating, and bloody or pus-like discharge. Surgical removal is the main treatment.
Uterine Tumors in Dogs and Cats
Uterine tumors are uncommon in dogs and cats, with leiomyomas being the most frequently seen type. They often produce no obvious signs and are found incidentally during abdominal palpation or ultrasound, though bleeding from the vulva can occur. Surgical removal of the uterus and ovaries is the treatment of choice.
Anterior Uveitis (Iridocyclitis) in Dogs and Cats
Anterior uveitis is inflammation of the iris and ciliary body in dogs and cats, causing pain, redness, and light sensitivity. It may arise from eye trauma, infection, or disease elsewhere in the body and requires prompt treatment to protect vision.
Optic Neuritis in Dogs and Cats
Optic neuritis is an inflammatory condition of the optic nerve that can cause sudden, often bilateral blindness in dogs and cats. The underlying cause is frequently unknown but may follow ocular trauma or infection, and prompt veterinary care is needed to protect vision.
Canine and Feline Glaucoma: Symptoms, Treatment, and Prevention
Glaucoma is raised pressure inside the eye of dogs and cats from blocked fluid drainage, damaging the retina and optic nerve and risking blindness. It is managed with pressure-lowering drugs and, sometimes, surgery.
Canine and Feline Keratitis: Symptoms, Treatment, and Prevention
Keratitis is inflammation of the cornea in dogs and cats from trauma, microbes, or chemicals, causing pain, cloudiness, and ulcers that can threaten sight. Prompt care protects the cornea and preserves vision.
