To care for a dog's wound, provide care right away to help prevent infections. If you are unsure what to do or whether your pet requires veterinary care, remember that it is always better to err on the side of caution when it comes to your pet's health. When in doubt, contact your veterinarian or an emergency veterinarian right away. Gently Cleanse Your Dog's Wound by rinsing it in a clean bowl or bucket of warm water to remove any dirt and debris. Use Light But Firm Pressure to Stop the Bleeding with a clean towel if nothing is stuck in it. Cover the Wound in a Clean and Sterile Bandage by applying antibiotic ointment and wrapping the wound in a sterile bandage. Check your dog's wound at least twice a day to ensure that infection does not set in and that healing is proceeding normally. Clean the wound twice a day with water or a pet-safe antiseptic solution, and contact your veterinarian immediately if the wound becomes inflamed or shows signs of infection. The four main stages that a dog's wound will go through as it heals are: Inflammation, Debridement, Repair, and Maturation.
