Canine allergy is very common with over 1 in 7 having some type of allergy. Allergic reactions in dogs are different than what happens in people. In humans, allergies usually cause problems with breathing. In dogs, allergies usually affect the
skin
and cause itching.
Causes of Canine AllergyThere are 3 causes of canine allergy:Insects –
Fleas
(most common allergy) and other biting insects Symptoms of Canine AllergyAllergic reactions in dogs can either happen immediately after exposure to an allergen (something that causes allergy) or can be from a delayed reaction to an allergen.Constant licking of paws - itchy paws is a common symptom of allergies (more than a stuffed nose). Other common symptoms to allergy included face-rubbing, belly-licking and ear infections. Canine HivesImmediate allergic reactions (within 30 minutes) usually cause canine hives on the skin. They can appear anywhere and usually disappear in 24 hours. You can recognize hives by a raised appearance, circular shape and itch. Your dog’s hair may also be raised in patches.Hives are most often caused by insect bites, drug allergy (after vaccination common cause), insecticides (lawn treatments), new foods or soaps. Treatment of HivesHives disappear once the cause is no longer in contact with your dog. Determine what has changed in the past several hours such as a new food or if you took your dog on a walk to a new area.For food allergies you can give your dog Milk of Magnesia (consult your Veterinarian first, suggested dose 7 to 25 ml. per pound orally once only) that quickens removal of food from your dog's stomach. If hives are caused by soap or insecticide, give your dog a bath using products you know are safe. Like humans, you can also give your dog Benadryl(2 mg per pound orally every eight hours). For extreme cases your Veterinarian may also prescribe Cortisone treatments. The saliva in the fleas’ mouth causes flea allergies. A typical flea allergic reaction will have your dog itching the moment they come in contact with the fleas with the itch continuing even after the fleas are killed.
