Dog Sores on Back After Seizure

My dog had a seizure so we took her to vet. When we got back home we noticed her back felt wet and there were several sores oozing with puss. Some of about the size of a dime, nickel or quarter. The sores are red with puss.

Editor Suggestions for Causes of Dog Back Sores

Hi Misty,

I'm sorry to hear about your dog's sores. Only an in-person visit can provide information on the exact cause of the sores. That said, here are some possible causes for sores that suddenly appear on a dog's back:

Stress or Anxiety-Related Behavior: If the dog is stressed, especially after a medical event like a seizure, it might engage in compulsive scratching or biting, leading to sudden sores.

Acute Allergic Reaction: A reaction to a new food, medication, shampoo, or environmental allergen like a plant or insect bite could cause sudden sores.

Trauma or Injury: If your dog has scratched, bitten, or injured itself, this can cause immediate wounds that may become infected and ooze pus.

Insect Bites or Stings: Bites from fleas, ticks, or mites, or stings from bees or wasps, can cause immediate skin reactions, leading to sores.

Burns or Chemical Exposure: Contact with hot surfaces or caustic substances could cause immediate skin damage and subsequent sores.

Bacterial Infection: While usually developing over time, bacterial infections can sometimes appear suddenly, particularly if there's a break in the skin allowing bacteria to enter.

Immune-Mediated Conditions: Certain autoimmune or immune-mediated conditions might cause sudden skin changes, including the rapid development of sores or ulcers.

The sudden nature of these sores underscores the importance of a prompt veterinary evaluation. Identifying the underlying cause can help tailor the treatment and prevent further complications.

Until then you can:

Clean the Sores: Gently cleanse the sores with a mild antiseptic solution (like diluted chlorhexidine) or saline solution. Avoid using alcohol or hydrogen peroxide as they can be too harsh on the skin.

Apply a Topical Antibiotic: If you have any over-the-counter pet-safe antibiotic ointment (e.g., Neosporin), you can apply a thin layer to the affected areas. Avoid using any products meant for humans without consulting a veterinarian. You can also use medicated pet safe wipes.

Prevent Licking or Scratching: Consider using an Elizabethan collar (cone) to prevent your dog from licking or scratching at the sores.

Keep a Close Eye on the Sores: Monitor the sores for signs of worsening, such as increased redness, swelling, or foul odor. If you notice any of these signs, contact your veterinarian immediately.

Again, please consult with veterinarian you just saw as soon as possible as the above are just some general guidelines vs. getting specific advice for your dog's medical condition.

Best,
