  • Dorzolamide is applied to the eye and is used off label to treat glaucoma (increased eye pressures). Give as directed by your veterinarian. Common side effects include stinging sensation, eye redness, watery eyes, and light sensitivity. Do not use in pets that are allergic to it or sulfonamides. If a negative reaction occurs, please call your veterinary office.

  • Doxepin is given by mouth and is used off label to treat psychogenic dermatoses such as excessive grooming and psychogenic alopecia. Give as directed. The most common side effect is sleepiness. Do not use in pets that are allergic to it or other tricyclic antidepressants, in pets currently using an MAOI or flea/tick collar, or in pets undergoing skin allergy testing within two weeks. If a negative reaction occurs, please call your veterinary office.

  • Doxycycline is an antibiotic given by mouth in the form of a tablet, capsule, or liquid, used off label to treat certain infections.

Do not use in pregnant pets and use cautiously in pets with liver disease or in young pets. If a negative reaction occurs, please call your veterinary office.

  • This article reviews the advantages and limitations of the different food forms available for dogs, including dry, canned, and semi-moist foods. Dry food, or kibble, is easy to portion control and can be fed in puzzle toys. Canned food is a good option but more expensive than kibble and does not last as long once opened. Semi-moist foods are generally not recommended as the main diet due to their high sugar and sodium content, as well as difficulty with portioning. Feeding a combination of canned and dry daily is an option and can help with acceptance of a variety of textures later in life.

  • E-cigarettes are battery-operated devices used to create and inhale an aerosol composed of nicotine, flavorings, and other chemicals. If a companion animal ingests an e-liquid, signs of nicotine poisoning occur rapidly. The nicotine associated with e-cigarettes, even without tobacco, poses a serious health threat to dogs and cats.

  • Ear canal tumors are abnormal growths that can develop from any part of the ear canal (the skin, the glands of the skin that produce earwax and oil, and the underlying connective tissues, muscles, and bones). Initially, these tumors may appear as one or more pink, white, or purple nodular masses in the ear canal. If benign, they may grow to a certain size and may or may not be problematic. If malignant, they may grow, ulcerate (break open) and bleed, and nearly always become infected, causing recurrent or chronic ear infections. The treatment of choice for ear canal tumors is surgical excision.

  • Ear cleansing/drying products are used over-the-counter to treat and prevent ear infections in many species of pets. They come as a liquid solution that is used topically within the ear canal and are typically used in the ears after debris and wax have been removed using a cerumenolytic cleanser.

  • Infection of the external ear canal (outer ear infection) is called otitis externa and is one of the most common types of infections seen in dogs. Nearly all ear infections that are diagnosed and treated can be successfully managed. However, if an underlying cause remains unidentified and untreated, the outcome is less favorable.

  • The ear mite is a surface mite that lives on cats, dogs, rabbits, and ferrets. It is usually found in the ear canal but it can also live on the skin surface. Mites are barely visible to the naked eye. Clinical signs of infestation vary in severity and may include ear irritation, leading to scratching at the ears or head shaking, dark waxy or crusty discharge from the ear, areas of hair loss resulting from self-trauma, a crusted rash around or in the ear, and an aural hematoma. Your veterinarian will advise you about which insecticidal products are suitable. Your veterinarian may want to re-examine your pet to ensure that the mites have been eliminated after the initial treatment has been performed.

  • Echinacea is given by mouth and is used over the counter and off label to improve immune system function and reduce inflammation. Give as directed by your veterinarian. Side effects are uncommon but may include vomiting and diarrhea. Do not use in pets that are allergic to it. If a negative reaction occurs, please call your veterinary office.
