Anaphylaxis In Dogs - Symptoms, Causes & Treatment

Author WDF Staff


Anaphylaxis in dogs is a severe health problem that can affect your dog. It is widely known as an allergic reaction that can lead to anaphylactic shock and, in some cases, death. Dogs can be allergic to any substance, and because of that, anaphylaxis is quite unpredictable. In modern times dogs are exposed to many different substances, including vaccines, medications, new foods, or chemicals used for food preparation, and they all can lead to anaphylaxis. This is a severe health problem, and if you suspect your dog has anaphylaxis, you should seek vet help.

Anaphylaxis in dogs

Anaphylaxis is an abnormal reaction to any foreign substance. There are a few substances that are dogs more prone to, and they include:

  • Food proteins
  • Different medications
  • Chemicals
  • Insect bites
  • Antigens in vaccines

Dogs' immune systems will overreact to the foreign substance and will cause a big reaction.

How to treat anaphylaxis in dogs?

Anaphylaxis is a medical emergency, and you must act quickly. The first step your vet will take is to remove the substance causing this reaction (if it's possible to remove it). Next, your vet will monitor your dog for any problems for 24- 48 hours. In some cases, your vet will need to use adrenaline for your dog to get this reaction under control.

Some dogs will require IV fluids and oxygen to stabilize themselves. If your dog has ever had an allergic reaction in the past, you must share it with your vet because the course of treatment may be different.

What is the prognosis?

The prognosis will depend on the severity of the shock. Your dog will have a better chance of solving this medical issue if you take him to the vet's office in time. If your dog has milder symptoms, he will, in most cases, be better within two days.

Anaphylactic reactions will worsen with each episode; you must ensure that your dog is not exposed to the substance causing anaphylactic shock. If your dog suffers from this medical condition, your vet can prescribe you some medication you can keep at home in case of an emergency.


Anaphylaxis in dogs is a serious health problem that can affect your dog. If you notice any of the symptoms connected to this issue, you should immediately seek help from your vet. Your vet will remove the substance causing this health problem and monitor your dog for the next two days. In most cases, dogs will make a full recovery.
