What can you do if you notice that your pet is having an allergic reaction, and when should you go to the vet as soon as possible?
What can my dog or cat be allergic to?
It differs from animal to animal what they are allergic to. For example, some dogs and cats are allergic to gluten or dust mites. However, in this article, we are only discussing acute allergic reactions. This is a response to a temporary trigger, such as an insect bite or a specific plant. Sometimes, we also see side effects from applying a flea pipette.
Symptoms
Symptoms of an allergic reaction:
-
Skin reactions
Swelling, lumps that vary in size, often caused by allergies to plants, insects, food, or medication. Urticaria appears quickly, within hours or a day, and usually disappears within 24-48 hours. The itching can vary, and sometimes steroids are needed.
-
Swelling of mucous membranes
In severe cases, eyelids, lips, nose, cheeks, and paws can swell (angioedema). These swellings can narrow the airways, causing breathing problems. Contact your vet immediately.
-
Gastrointestinal issues
Dogs or cats may suddenly vomit, followed by diarrhea. This is the body’s defense mechanism to quickly expel toxic substances.
-
Anaphylactic reaction and shock
A rare but life-threatening allergic reaction. Symptoms develop quickly within 20 minutes of contact with the allergen. Swelling, itching, vomiting, diarrhea, and in extreme cases, shock. Shock can quickly lead to unconsciousness and death without treatment. Treatment with intravenous fluids and oxygen is essential.
