Dr. Robin Zuckerman, a BML member in emergency veterinary practice in Portsmouth , NH sees hives on a regular basis.
Hives are bumps on the skin that are usually itchy and swollen.
They range from nickel to quarter sized lesions and can be found any where on the body. Frequently, hives are caused by immune reactions. There are 4 types of immune related reactions and two of them can manifest with hives as part of the clinical picture. The general health of the animal is not generally affected. However, certain side effects of the hives can cause secondary problems.
