When your dog has a hypersensitivity to something, they can develop hives when it comes into contact with the substance, as it will trigger the formation of antibodies. There are many possible reactions that can cause hives, along with other symptoms. Some examples of other symptoms include dry skin and oily hair, hair loss, intense itching, warts and bumpy spots, trouble breathing, smelly fur, puffing up around the eyes and face, rashes, skin lesions and yellow skin appearing in patches.
Bug Bites
The most common insect bites that occur on dogs are wasp, bee, hornet or ant stings. Your pet will most likely begin to show signs of the bite after 20 minutes, but the symptoms can continue to develop 12 to 24 hours after the bite occurs. The most common area for dogs to get bitten is on the head and face or around the mouth. If the sting takes place on the stomach, it is most likely done by an ant or wasp. Bug bites can cause inflammation and irritation, but should subside within an hour. Stings done by honey bees or wasps will result in stings that will be red and feel hot to the touch. If the stinger of the insect is left in the skin of the dog, it can continue to release venom. Ticks, spiders and fleas can also bite and leave similar symptoms behind. Insect bites can cause swelling on the eyelids, lips, and entire face, which can make it difficult to breathe. Your pet may have overall weakness, wheezing, a weak pulse, unconsciousness, a fast heart rate and fever that can lead to shock, hives, vomiting, diarrhea, collapse or trembling.
Soaps Or Shampoos
Dogs can have reactions to soaps and shampoos when the pet’s body considers an ingredient in the shampoo as an intruder. There are a number of ingredients in dog soaps and shampoos that can create a negative reaction from your pet. The reactions can occur quickly after the dog has come into contact with the irritant, and will often worsen with repeated exposure. Symptoms often noticed with soap and shampoo allergies are hives, obsessive licking, biting their paws, shaking their head, rubbing their feet, skin rashes and infections, chronic ear infections and inflamed feet, bald patches, lesions that look like blisters, skin ulcerations and swelling around the face.
Foods
Food intolerance will occur when your dog’s immune system reacts with a specific ingredient in a food. Food allergies can take months or even years to develop, but once your pet becomes allergic, he will most likely always be. Sources of protein, like meat, are the most common ingredients that cause reactions. Besides meats such as beef, there is wheat and milk products can be sources of irritation. Infections and inflammation, past surgeries and sometimes medications can sometimes make allergies occur as they can cause damage and alter the digestive system. Symptoms include vomiting and diarrhea, wheezing, sneezing and coughing, flatulence, red and inflamed skin, excessive scratching leading to hair loss or chronic ear problems.
Dogs at any age can begin to develop food intolerances, although some breeds seem to develop them more easily. These include Irish Settlers, Cocker Spaniels and White Terriers. Food allergies will mainly take form in skin irritation or upset digestive systems. Skin lesions will appear mainly around the face, ears and feet. Pets who continuously experience external ear infections should be checked for food allergies. Food intolerances can have similar signs as other illnesses that can be serious and therefore your pet should be brought to the vet as a precaution. These allergies will most likely be present for the rest of your pet’s life, so the main goal will be to manage it by finding replacement foods for the ingredient that is causing the intolerance. Dietary elimination trials can be used to determine which ingredient is causing the symptoms. When you perform the trial, be sure to eliminate any other types of food, snacks and treats as well in order to determine what food is causing the reaction.
Drug And Medication Allergies
Some drugs and medications that you are giving to your dog may possess an ingredient that will cause their immune system to react. Moreover, over vaccinating or over medicating your dog can actually increase their immune system’s hypersensitivity and therefore make them more susceptible to allergies.
Pesticides Or Natural Pollens
Pesticides or other toxins that you may be using in or around your home can have the same negative effect on your dog. Pollens and plants that your pet could be exposed to may also trigger a response from the immune system. They may contain something that your dog reacts to and can cause discomfort in the form of hives, along with other symptoms. Ragweed, fertilizers, insecticides and pesticides are all potential causes. Try to think of times that your pet has had an allergic reaction and match it with what was present in their surroundings at or before that time. This will allow you to narrow down the possible sources of irritation.
