Pet Symptoms
+-+1+Capsule.jpg)
Allergies occur when there is an exaggerated response from the immune system to something. The substances that cause this trigger are referred to as allergens. The majority of these are proteins, either originating from plants or animals. When a pet is exposed to such allergens repeatedly, the body can become sensitive to the substance, thus leading to an overreaction of the immune system. Normally, immunity from bacteria, viruses, and other harmful substances is provided, but in pets with allergies it is the opposite; the immune system may actually cause more harm than good.
When an allergic response occurs, the body releases a chemical in the body called histamine, which can cause mild to severe symptoms. Some of these include; sneezing, coughing, difficulty breathing (congestion, wheezing, etc.), itchiness, ocular discharge, recurrent ear infections, inflamed/irritated skin, skin infections, vomiting, loose bowel movements, snoring (due to swelling of the throat), and chewing or licking the feet excessively.
The variation in symptoms along with the list of potential causes can make it difficult to diagnose allergies in dogs and cats. However, learning about the common allergens in pets can be helpful in arriving at a conclusion. Substances commonly associated with allergies in pets include; pollen (from trees, plants, flowers, etc.), mold, dust, dust mites, smoke, common food ingredients such as chicken and beef, dander, medication, flea saliva (medically termed flea allergy dermatitis), shampoos, plastic (such as a feeding bowl or toy), and fragranced products.
The only way to completely prevent and get rid of allergies is to avoid the triggers. This can prove impossible, which is why there are medications available to help manage the symptoms. Like with humans, pets with allergies are usually prescribed antihistamines to help with itching, sneezing, etc. Allergy injections aren’t as common, but can also be prescribed to help the immune system become more resistant to allergens. There are even special foods and supplements made especially for pets with allergy problems. In severe cases, steroid drugs may also be prescribed, but these are usually used as a last resort because of the possible side effects.
