Fever blisters, often referred to as canine cold sores, are lesions that can develop on a dog’s lips or inside its mouth. These can be painful and uncomfortable for your furry friend, prompting many pet owners to seek effective treatments.

In this piece of blog post, we will discuss a most asked question, “Can Neosporin ointment be used for fever blisters in dogs?


What is the Canine Herpes Virus?

The primary cause of fever blisters in dogs is the canine herpes virus. Similar to the herpes virus in humans, it leads to:

  • Dog lip sores
  • Dog mouth ulcers
  • Canine blisters

Neosporin and Its Application as a Topical Treatment

Neosporin Ointment on Dogs’ Fever Blisters (Cold Sores)

Neosporin as an Antibacterial Ointment

Neosporin is a triple antibiotic ointment that combines Bacitracin, Polymyxin-B, and Neomycin. It’s designed for:

  • Healing minor cuts
  • Preventing bacterial infections
  • Aiding the healing process

There’s often a debate around the safety of over-the-counter treatments like Neosporin for pets. While it is safe for some conditions, it’s crucial to consult veterinarian advice before applying it to dog skin infections or irritations.

Possible Side Effects

Some dogs might experience:

“Always conduct a patch test or consult a veterinarian before introducing any new treatment to your pet.”

Canine Skin Care and Fever Blister Treatment

The Role of Topical Creams

Topical treatments, including antibacterial ointments and soothing balms, play an essential role in:

  • Soothing dog skin irritation
  • Speeding up the healing process
  • Protecting against further infection

Ointment Application on Dogs

How to apply ointment to dogs:

  1. Clean the affected area with mild soap.
  2. Pat dry gently.
  3. Apply a thin layer of the ointment.
  4. Prevent your dog from licking the area for a few minutes.

What if a dog ingests Neosporin?

If a dog licks or ingests a small amount of Neosporin, it may not necessarily be toxic. However, larger amounts can cause gastrointestinal upset, including vomiting or diarrhea. One particular concern is the antibiotic Neomycin, which is one of the ingredients in Neosporin and can be harmful if ingested in large quantities.


  • Always apply a thin layer of the ointment to the affected area.
  • Prevent your dog from licking the treated area.
  • If your dog does ingest a significant amount of Neosporin, contact your veterinarian or an emergency pet poison hotline immediately.

While Neosporin can be useful, other pet-safe products are specifically designed for canine skin conditions and can be included in a canine first aid kit. These alternatives might offer better protection against certain canine skin issues.

  • Always ensure products used are safe for dogs.
  • Keep a well-equipped canine first aid kit.

If you notice:

  • The fever blisters are spreading rapidly.

  • The blisters don’t improve after several days of treatment.

“Your dog’s health and comfort should always be the top priority. When in doubt, consult with a veterinarian.”

Concluding Thoughts on Dog Health Tips and Wellness

Taking care of a pet involves a deep understanding of their health issues, available treatments, and when to seek professional help. Whether it’s choosing antibiotics for dogs, seeking treatments for bacterial infections in dogs, or finding the right topical cream, pet wellness is paramount.

Always prioritize your dog’s health, stay informed, and provide them with the best care possible.
