Article in English: Once you've gotten the bleeding under control, you can start the cleaning process. If your dog has long hair, you may need to trim it away, but do so only if you can do it safely. If you don’t have clippers, carefully use blunt scissors to shorten the hair, but don't try to get down to the skin with scissors, as this increases the chance of further injury. Clearing away the dog's fur will let you a good look at the wound, and will keep hair from trapping dirt or irritating the exposed flesh. Add 2 tsp of sea salt to 1 cup warm tap water, and stir until it dissolves. Fill a turkey baster or syringe (without the needle) with the mixture, then squirt it gently into the wound until it's clean. The tissue should be clear and glistening before you stop flushing the wound.  If you don't have a baster or syringe, pour the water directly over the wound. If the wound is on the paw, you can soak the foot in a bowl, baking dish or small bucket for three to five minutes. Have a towel handy to dry the paw. Dilute Betadine (Povidine Iodine) or Nolvasan (Chlorhexidine) in warm water. Use this solution as a final rinse or soak. You can also use these solutions instead of saline when you're first cleaning the wound. A sterile gauze is ideal, but any clean absorbent material will be fine. Don't rub or scrub at the wound. Instead, pat it gently to avoid causing more pain or injury. Be aware that a spray might scare your dog, and may even sting for a little bit. Don't use creams and ointments if you have another option, as they might attract dirt to the wound. Furthermore, your dog will likely try to lick it off, so use those products only if you can prevent the dog from bothering the area. You can either wrap the treated area with protective gauze or use an Elizabethan collar.  Be careful that you don't spray anything into the dog's eyes. Don't use ointments with steroids like hydrocortisone or betamethasone that may interfere with the wound's healing process. Use only antibiotic ointments. Do not use antifungal creams...
