Earlier this summer, we received a heartbreaking email from a DJANGO Dog Blog reader (transcript below). Jeanette's dog, Sam, had sadly just passed away from tetanus, a rare but gruesome disease. Jeanette reached out to us to share her dog's traumatic experience with tetanus and asked that we spread awareness and share important information about the disease. In doing so, perhaps we could help prevent another dog's death from tetanus in the future.
If I am being 100% honest, I (Steph) did not know anything about tetanus in dogs before Jeanette reached out. Sure, I had heard of tetanus in humans and received tetanus vaccinations throughout my life...but dogs? I never realized dogs could be susceptible to this disease. After some preliminary research, I realized how important it is for us dog owners to be aware of tetanus in dogs, the disease's symptoms, and how our four-legged friends can contract the disease.
Since receiving Jeanette's heart-wrenching email, I've done extensive research on tetanus in dogs. I also spoke at length with Dr. Shadi Ireifej, the Chief of Medicine at Vet Triage, who helped me further understand risk factors and treatment options for this disease.
Here is everything you need to know about tetanus in dogs: the causes and symptoms of the disease, risk factors, treatment options and costs, side effects, and tips for prevention.
Tetanus is caused by bacteria called Clostridium tetani (C. tetani). Clostridium tetani are primarily found in dirt, dust, and feces.
When C. tetani bacteria spores enter a dog’s body through a deep wound or open sore, they multiply. As the C. tetani bacteria die, they produce a neurotoxin called tetanospasmin. This neurotoxin binds to the dog's nerves, eventually migrating to the brain and spinal cord. Once this occurs, neurotransmitters that control movement, touch, pressure, temperature, and pain (glycine and GABA) cannot be released. This leads to spasms of voluntary muscles and other symptoms (more on symptoms below).
There are two types of tetanus:
Signs and symptoms of tetanus in dogs can appear anywhere from three days to three weeks after the dog is wounded and exposed to C. tetani bacteria. Symptoms can be mild or severe and include:
If your dog is exhibiting any symptoms of tetanus, please visit your vet as soon as possible. Dr. Shadi Ireifej emphasized that dogs that cannot breathe or move should be immediately rushed to the nearest emergency veterinary clinic.
Tetanus is fortunately rare in dogs.
Dr. Shadi Ireifej has worked in veterinary medicine for 14 years. He saw one case of canine tetanus at Cornell University in 2004. According to The Canadian Veterinary Journal, horses, humans, and sheep are 600 times more susceptible to tetanus than dogs. Cats and birds are 10 times more resistant to tetanus than dogs.
Some dogs are more at risk of tetanus than other canines. Larger dog breeds that live on farms or in the country have a greater risk of contracting the disease. Dogs that have access to manure or are close proximity to dead animals are also much more at risk of tetanus.
Dogs that spend extensive time outdoors can get tetanus from foxtails, or grass seed awns. If not discovered quickly, these can burrow into your dog’s vital organs and blood vessels. According to the UC Davis School of Veterinary Medicine, 27 percent of canine tetanus cases are caused by foxtail burrs.
Newborn puppies can get tetanus through their umbilical stumps. Dogs under 2 years old are also at greater risk of tetanus because they are more inclined to put dangerous, infected items in their mouth (dirty sticks, rusty nails, glass, etc).
HOW IS CANINE TETANUS DIAGNOSED?
There is no easy diagnostic test for tetanus. Blood tests aren’t accurate because C. tetani does not live long in the air. A tetanus diagnosis is usually made based on your dog’s appearance and the history of his wound. If you did not notice your dog’s wound 10 to 14 days ago, your vet may order a urinalysis, electrocardiogram, and chest X-rays.
Tetanus treatments can cost anywhere from $15 to $20,000. The cost of treating tetanus in dogs will depend on the severity of the case and required treatment. Mild cases of canine tetanus that only require a vet visit, wound cleaning, and antibiotics may cost up to $200. Severe cases of tetanus requiring long-term sedation, stabilization, and round-the-clock nursing care can cost well into the thousands.
Here is a list of approximate prices for common tetanus treatments. Please keep in mind that costs can vary extensively based on your location and veterinary clinic (we live in NYC so everything costs more here):
According to the Journal of Internal Veterinary Medicine, 77 percent of dogs that survive tetanus have a REM sleep behavior disorder (RBD). This usually occurs two weeks after dogs are discharged from the vet.
Your dog may twitch, run, or whine in his sleep. While anti-epileptic medications won't help, symptoms should not get worse over time. RBD may resolve after several months.
Because tetanus is relatively rare in dogs, there is no vaccine currently available for canines like there is for humans.
If your dog has a wound without symptoms, Dr. Ireifej recommends immediately cleaning it with mild soap and water, iodine, or dilute peroxide to rid the site of bacteria and prevent infection. Dr. Ireifej also advises applying Neosporin to your dog’s cleaned wound and bandaging it to prevent the introduction of additional bacteria.
Regardless of how the wound appears, place an e-collar on your dog and visit your vet as soon as possible. Your vet will be able to properly clean the wound further (if required), prescribe any necessary antibiotics, and apply any needed stitches.
Here is the heartbreaking email we received from Jeanette, a DJANGO Dog Blog reader and dog mom to Sam. Jeanette reached out to us to share her and Sam's heartbreaking experience with tetanus in hopes that we would share information about the disease with our readers.

"Our dog just passed away from tetanus. I’m reaching out to you so that our story can bring awareness to this “rare” disease that seems to affect quite a bit of dogs annually. We first noticed our dog Sam’s face was really weird. It looked like she was locked in a smile (we later found out the name was “the sinister smile”) but very uncomfortable. Upon taking her to a vet they diagnosed her as dehydrated and prescribed antibiotics, lots of water, and rest. But later that day her symptoms seemed to be getting worse and she seemed to be very out of it. We decided that she was behaving in a very alarming and not normal way so we took her to a 24 hr hospital, California veterinary specialists. From there we received the news that our dog had contracted tetanus, a very rare but gruesome disease. So just like any other millennial couple my husband and I began our google research to try and find as much information on this disease as possible. Unfortunately there was little to no helpful information on recovering from tetanus and a lot of really sad photographs of dogs that looked like they were suffering. 2 days later our dogs symptoms got so bad that she was unable to open her mouth (referred to as lockjaw) and was having a very difficult time trying to find a good position so her airways opened up to breathe. The dr in that hospital recommended her staying in the hospital for 2-3 weeks, but possibly over a month, in intensive care in order for them to try and save her. But even then the survival rate they gave us was 30%. We did not have the money to pay for a months stay at a hospital for a 30% chance survival. We could’ve taken her home but without the proper equipment and knowledge to care for her it was very likely that she would suffocate because of the disease and die at home. Our pup was suffering and we made the very difficult and heartbreaking decision to say good bye to her. I want to try to reach out to as many animal blogs as I possibly can to spread awareness and maybe encourage some young vets out there to push for some type of vaccine for tetanus in dogs. Or at least for anyone to do more research for dog owners like us so that we can keep our pups safe."

What is been missing from dog diets ever since we started feeding them processed pet foods? Naturally occurring probiotics from whole foods, says Dr. Ian Billinghurst, the father of biologically appropriate, ancestral nutrition for dogs. Thirty years ago, he taught us about the evolutionary diet for dogs with his book, Give Your Dog a Bone. He also famously coined the term “BARF” (Biologically Appropriate RAW Food).
In this DJANGO Dog Blog article, we host Dr. Billinghurst and Rob Ryan, the founder of GussysGut.com for a conversation on good bacteria. Dr. Billinghurst and Rob Ryan also address why relying on probiotic supplements may not be the best long-term answer for our pups.
While interviewing Dr. Ian Billinghurst, the father of the raw dog food movement, we discovered he is the senior advisor to Gussy's Gut. Dr. Billinghurst came out of retirement to create the dog supplement company which produces a fermented and probiotic rich dog superfood topper called “Daily”. He’s called the product “the single most important upgrade to canine nutrition in over 25 years.”
They source the highest quality and most responsibly-sourced organic ingredients. The supplement is made from 19 superfoods that come from biodynamic, grass-fed, organic, and regenerative farms.
Unlike raw vegetables, fermented foods like Gussy's Gut are easier for dogs to digest and their nutrients are more accessible to them. Studies show that dogs regularly given fermented foods often have fewer allergies, better blood sugar levels, and healthier stools.
If you are considering adding a high-quality dog food topper to your pup's diet, or if you simply want to better understand the canine health benefits of fermented foods, this DJANGO Dog Blog article is for you. Here is our comprehensive overview of Gussy's Gut, the freeze-dried, probiotic rich dog food topper.
