Skin conditions are one of the most common reasons people bring their dog to the veterinarian---itching, rashes and hair loss are extremely common. Itching is a symptom often of allergies, parasites or simply poor nutrition. While it's very important to have your dog diagnosed by a veterinarian for any skin condition, treating your dog from the inside out with good nutrition and supplements might be all it takes to stop the itching.
Instructions
Change your dog's food. While many people are unwilling to commit to a home-cooked or raw diet, there are plenty of alternatives for feeding a dog good nutrition with high protein, high fat and few carbohydrates.
Ditch the "weight control" kibble. According to Dr. Susan Wynn, executive director of the Georgia Holistic Veterinary Medical Association, vets can tell when a dog is eating this because it has dry skin, a poor coat---and it's still fat. Feed a higher quality food and supplement with cooked vegetables for bulk if you think your dog needs it.
Add fish oil to your dog's food. This supplies omega 3 fatty acids, something most commercial dog food is lacking. Fish oil is a natural anti-inflammatory and benefits the skin and coat. You can also add some omega 3-rich canned salmon, mackerel or sardines to your dog's food.
Give your dog a probiotic per day. Usually recommended for gastrointestinal issues, they can improve a dog's overall health, including better skin and coat and fewer allergic reactions, according to researchers at Oklahoma State Center for Veterinary Sciences.
Exercise your dog. Excessive scratching, licking and chewing can be caused by boredom, under-stimulation and stress--all conditions easily treated with some brisk exercise or playing.
