What are Skin Ulcers?
If your dog has an open sore, it is likely that he or she is suffering from a skin ulcer. These lesions usually indicate injury, infection, or disease and require an examination by a veterinarian to determine the underlying cause. Treatment and prognosis varies depending on the source of the ulcer.
A skin ulcer is a deep lesion that can be caused by a variety of factors, ranging from bug bites to cancer. Though the ulcer itself is not life-threatening, you should have a veterinarian examine your dog for underlying conditions, as skin ulcers are typically a sign of infection or disease.

Symptoms of Skin Ulcers in Dogs
A skin ulcer is visible as a lesion that may be oozing or leaking. These sores can occur anywhere on the body and are typically accompanied by depigmentation or hair loss, as well as inflammation or redness around the wound. Your dog may exhibit different symptoms depending on the cause of the ulcer, including lethargy, loss of appetite, pain, and depression.
Causes of Skin Ulcers in Dogs
Skin ulcers are lesions that affect deeper layers of the skin and result when the upper layer is compromised. These are a symptom of many different conditions and may occur for a variety of reasons, including:
Some breeds may be more susceptible to certain causes for skin ulcers, whether due to genetics, age, physical characteristics, or environment, though all dogs are at risk of developing these lesions over the course of their lives.
Diagnosis of Skin Ulcers in Dogs
If you notice a lesion on your dog’s skin, bring your dog in to a veterinarian for a thorough examination. Be prepared to provide a history, including your dog’s recent activity, places you may have visited, and any additional signs or behaviors that are out of the ordinary.
As part of this examination, the veterinarian may conduct blood tests, take cultures of any fluids to identify the infection, and perform a biopsy of the affected skin. This helps determine the cause of the ulcer and discover any other conditions. Depending on the results, the veterinarian may recommend further tests, such as x-rays, ultrasounds, or urinalysis, which will reveal more information regarding the root cause of your dog’s skin ulcers and show the extent of the condition. This allows the veterinarian to determine the best course of action and prescribe treatment accordingly.
Monitor your dog carefully throughout this process. Even if your dog does not initially exhibit unusual signs beyond the ulcer, further symptoms may still develop over time. Alert the veterinarian immediately if you notice any changes.
Treatment of Skin Ulcers in Dogs
Treatment varies widely according to the cause of the skin ulcer. Most lesions can be successfully treated at home, though the veterinarian may recommend hospitalization, depending on the underlying condition. In all cases, the ulcerated skin must be kept clean and free of pressure. The wound should be kept moist, as this allows sufficient blood to reach the area and enhances the healing process. You may want to ask the veterinarian about hydroactive wound dressings, which mold to the sore and keep the area moist without additional intervention.
If the lesion is the result of fungal or bacterial organisms, the veterinarian will prescribe medication to fight the infection. Any other conditions, such as cancer or burns, will need to be treated according to the veterinarian’s directions.
Treatment may need to be administered for several weeks as the wound slowly heals. During this time, you should monitor your dog for additional symptoms and to ensure that the skin ulcer is closing.

Recovery of Skin Ulcers in Dogs
The recovery process may take days to months, depending on the underlying condition. Prevent your dog from biting or licking the wound, and do not allow your dog to swim, as this may lead to infection. 
You may need to bring your dog in to the veterinarian for a follow-up exam to check how well the lesion is healing, as well as to monitor any underlying conditions. The ulcer itself should heal with proper care, though the overall prognosis varies according to the extent of the disease.
Cost of Skin Ulcers in Dogs
The treatment for a skin ulcer depends on the cause. However, most skin ulcers can be treated at home after consulting with a veterinarian. It’s important to keep the area clean to avoid infection. A soap made for sensitive skin, such as Cetaphil can be bought at most drug stores and can cost $3 per bar on average. The veterinarian may want you to use an ointment or cream to keep the area moist. Depending on the type of skin ulcer your dog has, an ointment or a cream may not be enough and may cause pain when applied. Check with your veterinarian about a skin care spray (such as Vetericyn) that can assist the healing process; keep it clean and avoid additional pain to the area. Vetericyn costs between $25 and $45 per bottle. The veterinarian may prescribe antibiotics to help treat the skin ulcer if the cause is fungal or bacterial. Antibiotics usually cost between $40 and $200. The total cost and treatment plan will vary greatly if the cause is cancer or a burn.

My pet has the following symptoms:
Raise Bump
I just got my puppy a couple weeks ago. I noticed on her leg she has a raise brown lump. Her appointment with the vet isn’t for another week and was wondering if you have any idea what this could be.

Thank you for your question. It is difficult to say what might be going on without seeing him, but it is possible that that lesion is a bacterial infection, or ringworm. Ringworm is treatable,but can be contagious to people, so it would be best to wash your hands after handling him, wash his bedding, and try to have an earlier appointment with your veterinarian so that they can examine him and confirm what that may be. I hope that all goes well for him.

Thank you for your question. Unfortunately, without being able to examine her, I can't say why she would have an open wound on her head. Dogs can get superficial skin infections, parasites, or trauma is that can cause wounds and the hair may fall out as a result. If this seems to be a sudden thing and there is not an explanation for it, it would probably be best to have her seen by a veterinarian. They can look at the wound, see what might be going on, and get treatment for her. I hope that she is okay.

Thank you for your question. Dogs can be affected by fleas and other parasites, or allergies, or bacterial infections. If she is not on regular flea control, that may be part of the problem. If it is itchy or red to the point where she won't leave it alone, then it would be best to have her seen by a veterinarian, as she may have a secondary infection and may need treatment. They will be able to tell you what might be going on with her, give you the best options for treatment, and make her feel better. I hope that all goes well for her.

My pet has the following symptoms:
A Growing Lesion On His Head
On the top of his head he has a growing sore (or lesion) - much like the skin ulcers described above here. Biggest concern is that it continues to grow. Right now it is about the size of a half dollar.

Thank you for your question. Some growths are quite benign, unless they continue to grow, and some growths are more malignant and need to be removed. Since I cannot see the lump, it would be a good idea to have him seen by a veterinarian, as they can examine him and see what type of growth this might be, and let you know more what plan would be best for him. I hope that all goes well for him.
