A skin condition known as pruritus causes an uncomfortable sensation that makes people want to scratch their skin. Itching is a symptom, not a diagnosis of a particular illness. Parasites, infections, and allergies are the three main factors that cause itching. There are several skin conditions that do not at first itch. Secondary bacterial or yeast infections may result in itching. It’s possible that the original cause has long since vanished by the time the itching starts.

A dog with pruritus will itch, bite, or lick its skin excessively. Itching can be widespread or localized. A complete physical examination and skin history will be conducted by your veterinarian. Your veterinarian will initially try to rule out parasites, like as mites and fleas.

Your veterinarian will then search for infectious sources of skin conditions. Itching is frequently brought on by bacterial and fungus infections. Scaling, stench, fluid leakage, and hair loss are frequently present alongside infections. Infected animals frequently scratch, rub, or lick their faces and feet excessively. This is especially true if they also have bacterial and yeast infections. Your veterinarian will frequently recommend a 21- to 30-day course of antibiotics if such an infection is detected.

Seasonal allergens are most likely the cause of dogs’ seasonal itchiness. Dogs with allergic itchiness throughout the year may have a food allergy or an environmental allergy (such as an allergy to dust mites). food intolerance dietary allergies Dogs can develop allergies to a variety of chemicals, including plant particles, other elements in the environment, or substances found in diet, just like people can. Allergens are these compounds. Allergens are either verified or omitted based on a diet trial’s outcome. Your dog is provided a diet during a diet trial that excludes the foods it usually eats. Your veterinarian will recommend a diet, frequently one that includes fish or other meats that haven’t been fed before. You must strictly adhere to the recommended diet, avoid giving treats that violate the plan, and help your veterinarian identify the food allergy.

Finding the root reason is essential to effective treatment. Dogs who have pruritus will need medical therapy if the reason of the itching cannot be determined or if treating the underlying illness does not stop the itching. The drugs glucocorticoids, essential fatty acids, cyclosporine, and oclacitinib are frequently recommended to treat itching.
