What Home Remedy Can I Give My Dog for Coughing? What Vets Say (2026 Update)
Last updated: October 22, 2026. Originally published August 2024.
This article is general information for pet owners, not veterinary advice. If your pet seems sick, or you are unsure, call your veterinarian.
- A cough is a symptom, not a diagnosis. No home remedy treats the cause, and the right step depends on why your dog is coughing.
- Go to an emergency vet right away for trouble breathing, bluish gums, belly heaving, collapse or weakness.
- Call your vet if a cough lasts several days with no improvement, or comes with low energy, poor appetite or colored nasal discharge. Puppies and senior dogs should be checked sooner.
- Never give human cough or cold medicine. Many contain ingredients that are dangerous to dogs, such as acetaminophen.
The sound of a coughing dog is worrying, and it is natural to look for something soothing in your kitchen. This guide has been rewritten with veterinary sources. We removed the dosing amounts and statistics from the 2024 version because we could not back them up. Here is what vets and veterinary schools actually advise.
First, decide how urgent it is
Cornell’s veterinary college describes respiratory distress as a serious emergency. Signs include a bluish tinge to the gums and muzzle, abdominal effort while breathing, an extended head and neck, increased breathing sounds such as wheezing, and weakness or collapse. If you see these, quickly and calmly take your dog to the nearest emergency animal hospital, and call ahead if you can.
WSU’s Veterinary Teaching Hospital says a cough may not need veterinary care, but if a dog coughs for several days with no signs of subsiding, it is best to see a veterinarian.
Common reasons dogs cough
- Kennel cough. PetMD describes it as a highly contagious respiratory infection that spreads where dogs gather, such as boarding, grooming and daycare. It usually causes a persistent, dry, honking cough. Many uncomplicated cases improve with rest and time, often in 10 to 14 days, but puppies, senior dogs and dogs with other health problems should be seen by a vet.
- Collapsing trachea. Cornell notes this progressive windpipe disease is common in toy and small breeds that are middle-aged or older, and causes a harsh, dry, “goose-honking” cough that excitement, heat, humidity, smoke or pressure on the neck can worsen.
- Heart disease. WSU says middle-aged to older small-breed dogs are more likely to have it, and the cough may follow exercise or excitement.
- Other causes. WSU also lists problems with the larynx or esophagus (food entering the airways), parasites and lung disease, which need an exam and tests to sort out.
Comfort measures vets generally accept for a mild cough
These do not cure anything, but they are low-risk steps to take while you arrange a vet visit or watch a mild case. Ask your vet if your dog has other health problems.
- Rest. PetMD says rest and limiting activity are often all that is needed in uncomplicated kennel cough.
- Steam. PetMD suggests letting your dog breathe warm, humid air by sitting with them in the bathroom while a hot shower runs. Keep your dog out of the water and do not leave them alone.
- Fresh water and appetite. Watch food and water intake and call your vet if your dog stops eating or drinking.
- A harness instead of a collar. Cornell recommends this for dogs with tracheal collapse because it avoids neck pressure.
- Clean air. Cornell advises avoiding cigarette smoke and hot, humid environments for dogs with airway disease.
- Keep infected dogs home. PetMD says dogs with kennel cough should avoid other dogs for at least two weeks after the cough stops.
What about honey, coconut oil and chicken broth?
Our 2024 version recommended honey, coconut oil, warm broth and a humidifier, with specific amounts and success percentages. We could not find veterinary sources to support those numbers, so we have removed them. Here is a safer way to think about each:
- Honey and coconut oil. We did not find a veterinary source we could cite for amounts or benefits. They are rich foods, so ask your vet first, especially for puppies and for dogs that are diabetic, overweight or have a sensitive stomach.
- Chicken broth. Check the label. Many broths contain a lot of salt, and the ASPCA lists onions and garlic among foods to avoid feeding pets.
- Humidifier. Moist air is a reasonable comfort step for some dogs, but Cornell says hot, humid conditions can aggravate a collapsing trachea, so ask your vet if your dog is a small or toy breed.
Do not use human cough medicine
Pet Poison Helpline warns that acetaminophen turns up in products labeled for cold and flu symptoms, allergies and fever, and that dogs have a narrower margin of safety than people. Read more in our posts on cough medicine for dogs and acetaminophen poisoning. Only give your dog a medicine your veterinarian has prescribed for this dog, at the dose they specify.
Frequently asked questions
When should I take my dog to the vet for coughing?
Go to an emergency vet for trouble breathing, bluish gums, collapse or weakness. Call your vet if the cough lasts several days, or comes with low energy, poor appetite, colored nasal discharge, or if your dog is a puppy or senior.
Is kennel cough contagious?
PetMD says it spreads easily between dogs through droplets and shared surfaces, but is not contagious to people.
Can I give my dog Benadryl, Robitussin or Tylenol?
Do not guess. Call your vet first. Some human products are dangerous for dogs, and the right choice depends on the cause of the cough.
Should I record the cough?
Yes. PetMD says a video recorded at home can help your veterinarian if your dog does not cough during the appointment.
