As with any open wound that is from an injury, the key to getting it to heal is to keep it clean and uninfected. The first step in cleaning a wound is to cut away the hair from around the wound. This can be done best with scissors and not electric shears. Prior to cutting away, use a lubricant that is water-based to wet the area. This will make it easier to cut and see the wound.
Treatment for dog sores begins with cleaning the sore. Gently clean the wound with some warm water. Then you will want to disinfect the wound with a disinfectant such as iodine using a warm cloth. Next, cover the wound with a clean, dry bandage. Disinfect and dress the sore at least twice a day until it is healed. Also, you may choose to use a supplement such as CBD Oil for dogs that will work to ease any pain caused by the injury. CBD is an all natural pain reliever that will work wonders. CBD can in many cases speed up the recovery process.
A common skin sore occurs on dogs from the result of an insect bite. Typically, this type of sore will heal on its own. However, if the sore is aggravated then you will need to take special steps to ensure your dog does not make it worse. Typically if a dog can reach the insect sore with his mouth then they will constantly lick it which can lead to infection.
A round, raw lesion occurs with flea and mite bites and is called a "hot spot". As the hot spot becomes irritated and it is caused by a bite then you will want to clean and cover the area or place a cone around your dogs head that will prevent them from making it worse.
If caused by something besides an insect bite then that is best left to a veterinarian, who will likely prescribe an oral antibiotic. In any case, you will want to keep the area clean and the area around the sore well-groomed.
Demodectic and Sarcoptic Mange
Mange is essentially many sores that form on a dog's body by mites. Demodectic Mange is the transfer of mites from a puppy's mother. Treatment is generally unnecessary and they will clear up on their own.
Sarcoptic Mange is a little more dangerous and is transferred from dog to dog. It is evident by a number of mite sores that produce puss. It can be isolated to a small area on the dog or be over the dog's entire body. This is treated with a lime sulfur dip that can be found in pet stores or by a prescription medication from a vet.
Treatment for dog sores is generally accomplished by good hygiene and a little first aid. The key is to identify the problem area, keep it clean and disinfected, and prevent the problem from getting worse. Only in rare cases will you have to ask for the help of a vet.
