If your dog has been bitten by a cat and keeps barking, it is most likely because he is in pain or frightened. Being bitten by a cat can bring many adverse consequences, including infection, bleeding, etc., so the wound should be treated promptly.
First, stay calm, keep your dog quiet, and check the wound. If the wound bleeds, cover the wound with clean gauze or towel and apply gentle pressure to stop the bleeding. Then, clean the wound, preferably with saline or iodophor disinfectant, to avoid infection. If the wound is very deep or large, seek medical attention as soon as possible and seek veterinary help.
At the same time, the dog can be fed painkillers or antipyretics to relieve its pain and discomfort. However, please note that you must consult your veterinarian before giving medication to your dog and follow your veterinarian's instructions.
Finally, you can observe the dog's behavior and physical condition. If the wound condition shows signs of deterioration, such as swelling, infection, etc., you should seek medical attention again in time. It is recommended to pay attention to the way dogs and cats get along with each other to avoid conflicts between the two and ensure their safety and health.
