Urticaria, commonly known as hives, typically lasts less than 24 hours for acute cases, although the condition itself may recur for up to six weeks. Chronic urticaria can persist for months or even years. In dogs, hives may result from allergic reactions to food, insect bites, medications, or infections. If your dog has hives, consult a veterinarian to determine the cause and appropriate treatment. In some cases, a vet may prescribe cephalexin for dog use to treat underlying bacterial infections that contribute to the condition. Always follow veterinary guidance when administering cephalexin or any medication to your pet.
