• Managing Feral Cats

  Feral cats are fiercely independent and survive (but may not thrive) without the help of humans. They avoid people and hide, back away, or flee when they spot humans. Lack of immunization, parasite control, adequate nutrition, and hygiene put feral cats at risk of many life-threatening problems. TNR (Trap, Neuter, and Release) programs are the hallmark of controlling feral cat populations.

• Multidrug Resistance Mutation (MDR1)

  Many herding breeds (most commonly Collies and Australian Shepherds) have a mutation at the MDR1 gene that makes them more sensitive to the negative effects of certain medications. These drugs include several antiparasitic agents (when given at high doses), the antidiarrheal agent loperamide (Imodium®), and several anticancer drugs. The effects of the mutation vary in severity, depending on whether the dog carries one or two copies of the mutation. There is a cheek swab or a commercially-available test that assesses blood samples for the presence of the MDR1 mutation.

• Nail Bind and Nail Prick/Quick in Horses

  When a farrier shoes a horse, accurate placement of each nail through the insensitive epidermal laminae of the hoof is essential. The nail must penetrate deep enough to hold firm, but not deep enough to penetrate the sensitive laminae of the hoof.

• Nutrition for Cats with Congestive Heart Failure

  The clinical signs of heart failure are seen in many cats as they age. The two most common causes of CHF are chronic valvular disease and hypertrophic cardiomyopathy. Hypertension (high blood pressure) may contribute to heart disease and CHF. Secondary diseases, such as obesity, excessively high thyroid, or kidney disease may require dietary changes. Key nutritional goals are to maintain a stable body weight, deliver appropriate calories, and feed a balanced diet that the cat will regularly eat.

• Nutrition for Dogs and Cats with Gastrointestinal Upset

  When the digestive tract is upset, vomiting and diarrhea may result. Since the causes of these symptoms are varied, it's best to consult a veterinarian. Often, a gastrointestinal (GI) diet is recommended to support the digestive tract and ensure the gut gets the nutrients it needs to recover. A bland diet of cooked chicken and rice might be recommended, but it has several limitations and is not appropriate for long-term feeding.

• Nutrition for Inactive Adult Cats

  Over 60% of cats in North America are either overweight or obese, so paying attention to the balance between activity and calorie intake is important. Nutrient formulation and portion control are the two most important aspects of weight control. Once you have chosen a formula and have calculated a reasonable daily portion based on calorie density, the best way to stay on track and prevent unwanted weight gain is to combine portion control with regular, formal weigh-ins.

• Nutritional Considerations for Large and Giant Breed Dogs

  Because of differences in large and giant dogs' energy and nutrient needs, some pet foods are specifically formulated for these requirements. Adequate diet and feeding management are important for adequate growth and preventing orthopedic problems and gastric dilatation-volvulus (GDV) or bloat. Specific recommendations are included for selecting an appropriate diet for a large or giant breed dog. Feeding management recommendations are also included.

• Nutritional Considerations for Toy and Small Dogs

  Because of differences in toy and small dogs' energy needs and size, it is essential to use pet foods specifically formulated for their requirements. Adequate diet and feeding management are important for proper growth and preventing excessive weight gain. Specific recommendations are included to select an appropriate diet. Feeding management recommendations for puppies and adult dogs are also included.

• Over-the-Counter (OTC) Medications That May Be Safe for Dogs

  Some over-the-counter human medications can be used for common ailments in dogs, but you must consult your veterinarian before using them to determine the correct dose and to ensure they will not interact with other medications your dog is taking. Some medications are toxic. If the condition you are treating does not respond to treatment, contact your veterinarian.

• Owning a Tortoise

  Tortoises can make great pets if cared for properly. With proper diet and housing, smaller species of tortoises can live 20–50 years and larger species can live up to 100 years. This handout outlines tortoise breeds, dietary requirements, environmental requirements, and veterinary care.
