If your dog is constantly scratching, biting, rubbing, and licking himself, he may be suffering from atopic dermatitis (skin allergies). Atopic dermatitis is a lifelong condition that can be seasonal or all-year-round and is one of the most common causes of itching in dogs. Skin allergies are a result of an incorrect response of the immune system to food and environmental substances. Cyclosporine is specifically prescribed for the control of atopic dermatitis. Cyclosporine for dogs works by suppressing the dog’s immune system response to allergens, providing him with relief from itchy and swollen skin and other discomfort caused by skin allergies. You can find Cyclosporine on Vetito veterinary pharmacy in soft capsules that are easy to give to your dog.
