Whilst not common, episodes of anaphylaxis in dogs and cats do happen, and they can be very confronting for pet owners, not to mention serious for the affected pet. We’re here to give you an injection of knowledge about anaphylaxis – why it happens, how to recognise it, and what to do if you suspect it in your pet.

What is anaphylaxis?

Anaphylaxis is an unusually severe allergic reaction to a foreign substance. Most commonly, the trigger will be an insect sting or bite, but pets can also be triggered by food proteins, chemicals or certain medications.

What are the symptoms of anaphylaxis?

The dramatic allergic reaction of anaphylaxis usually leads to a state of cardiovascular shock, where pets rapidly become unable to sufficiently circulate blood around their body. This often leads to wobbliness, weakness or fainting, and can also cause vomiting or diarrhoea (which may be bloody). Affected cats are particularly prone to developing sudden asthma-like breathing difficulties and excessive drooling as well.

Both dogs and cats suffering from anaphylaxis may also show symptoms of body-wide inflammation, such as a swollen face or red welts on their skin.

Due to insect bites being one of the most common causes of anaphylaxis, many pets will have just been outdoors when their symptoms begin.

What should you do if your pet shows anaphylaxis-like symptoms?

Because of its severe effect on the pet’s circulation, anaphylaxis is very serious and necessitates urgent veterinary treatment. Depending on the pet’s symptoms, this may include adrenaline injections to support blood circulation, intravenous fluids to improve blood volume, antihistamines, and medications to relax constricted airways.

If you suspect your pet is suffering from anaphylaxis, you should seek urgent veterinary care, preferably calling ahead to inform the clinic of your imminent arrival so they can prepare.
