A hot spot results from a variety of factors. Irritants—such as fleabites, mites or scratches—will produce hot spots. Behavioral issues—such as anxiety—can also lead dogs to chewing raw spots into skin. As hot spots rapidly worsen, immediate attention is necessary to treat the problem. Home remedies for hot spots will promote healing; however, consult your veterinarian for guidance.
Clip the Fur
Remove fur from around the hot spot with clippers or scissors. This allows adequate airflow to reduce moisture and promote healing.
Gently clean the affected area with cool water and mild soap--such as water-based or hypoallergenic soap--or astringent.
Steep black tea bags in water. Use the cooled tea bags as a compress on the hot spot, or use the cool tea as a rinse for the affected skin.
As dogs tend to worsen hot spots by licking and biting them, use an Elizabethan collar to prevent these behaviors.
Seek the underlying cause of the hot spot to prevent continuous infection. Treat flea or mite infestation, seek veterinary guidance, and confront behavioral issues.
