Just like humans, dogs can suffer from allergies. Many of the things that cause symptoms in people can also trigger canine allergies. Pollen, mold, dust, cigarette smoke, and certain foods can all set off an allergic reaction in dogs. Fleas are another major culprit. A single bite can make your dog itchy for up to three weeks. When allergies strike, it is important to work with your vet to isolate the cause so you can put an end to your pup’s pain. Sometimes, it takes some trial and error to discover what is irritating your dog, but once you do, treatment may be as easy as switching food brands or shampoos.
