Call a veterinarian immediately if you notice any of these signs. Allergic reactions in pets are sometimes immediate but can occur hours later. Allergic reactions should be treated as soon as possible to prevent your pet from going into shock. A veterinary exam needs to be performed on your pet, even if the reaction symptoms “get better”. Allergic reactions can result from a variety of causes including insect bites or stings, food reactions, and environmental issues.
