Here’s What to Do if Your Dog Chewed Your Inhaler

1. Ensure That Your Dog Is Safe and Stable.

Examine your pet immediately. If they are experiencing unusual signs or appear to be unwell, take them to a veterinary hospital. Call ahead to let the staff know you are coming.

2. Collect the Remnants of the Inhaler and Look up the Ingredients.

Collecting your inhaler from your dog will help prevent further damage and risk. Additionally, it will be important to know what medicine your pet has been exposed to.


3. Call a Pet Poison Helpline to Report the Possible Toxin Ingestion.

If your pet appears stable, you should call the ASPCA Pet Poison or the Pet Poison Helpline. These organizations will gather information regarding your pet, including their name, age, weight, and breed. Additionally, the consultants will look up the drug your pet was exposed to and will be able to determine exposure risks. After the veterinary consultant has gathered all the necessary information, they will be able to advise you on the next steps and potential medical intervention.


4. Record Your Case Number and Seek Medical Attention

The veterinary poison control consultant will provide you with a case number that you can relay to your local veterinary hospital. Your local veterinary hospital will use this number to access the treatment recommendations.

What Medications Are Typically Found in Inhalers?

Inhalers directly deliver medicine to the lungs. They are commonly used to treat asthma, a condition in which the lower airway closes due to an irritant or hypersensitivity. Other conditions that can be treated by inhalers include chronic obstructive pulmonary disease and allergies. Steroids and bronchodilators are common medications that can be found in inhalers, although other possibilities exist as well.

A Special Note on Albuterol

Albuterol is a medication found in inhalers that causes bronchodilation. Albuterol improves breathing by dilating the lower airways and improving oxygen exchange. Albuterol can even be prescribed to cats and occasionally dogs; however, the doses are specific. The concern with a dog chewing on an albuterol inhaler is the risk of inhaling a large dose simultaneously. An overdose of albuterol can result in reduced potassium levels, which causes negative effects on the heart, including heart rate elevation and potential heart failure. Dogs with an overdose of albuterol may be lethargic, have an abnormal heart rate, and have changes to their blood pressure.

Risk of Foreign Body

As with any type of non-food item that is consumed or gnawed on, there is a risk of gastrointestinal obstruction. A consumed foreign body may not be able to be digested by the body and may get stuck in the digestive tract, leading to pain and the need for medical or surgical intervention. The chewed-up inhaler must be closely evaluated for missing pieces. If pieces are missing, this should be brought to a veterinarian’s attention. Depending on several factors—including patient size and amount of inhaler ingested—radiographs and other diagnostic tests may be recommended. Based on the radiograph findings, the veterinarian will make suggestions on how to move forward best.

Conclusion

Although inhalers are useful medical tools when used correctly, they do pose a risk if used incorrectly or if accidentally consumed. The risk of inhaler ingestion or puncture is linked to the medication it contains. If your pet is not stable, you should seek veterinary care immediately. A poison control consultant should be contacted as soon as possible to determine the potential risks to your four-legged companion. As always, it is recommended to set your pet up for success by keeping your inhaler and other medications out of reach.
