Hives in an of themselves are usually not a serious condition and you may not even know that your dog has them unless you feel its skin. However, they can be indicative of a serious allergic reaction. You may feel welts or raised spots which means that it may have hives. Hives may make your dog itch and damage the skin by constantly scratching. Following the steps below will help you alleviate the discomfort of your dog's hives.
Give your dog an antihistamine like benadryl. An antihistamine will relieve your dog's allergic reaction and reduce its need to scratch. An Antihistamine may also induce sleep in your pet, which will also calm it down and make it less aware of the itchiness.
Soak the dog in cold water. Cold water is great for stopping itchy skin. Fill your bathtub or baby pool to submerge your dog in. If you can't do either, grab the hose and wash the dog down for at least 15 minutes.
Oatmeal is a wonderful remedy for itchy skin. Pour about a 1/2 cup of oatmeal flakes into the tub or pool to alleviate your dog's hives.
If your dog's hives are confined to one spot and it refuses to get into the bath, you can apply cold compresses. Wet a rag and put it on the skin over the hives and then apply an ice pack. You can use either a medical ice pack or a frozen bag of vegetables. Either one will help alleviate the hives.
Consult the vet. If your dog's hives don't go away after a few days or seem to get worse, contact your vet for further treatment.
