Just like humans, dogs can suffer from dog food allergies in addition to other types of allergies. Your dog could be predisposed genetically or it could be that its breed is more susceptible to certain types of dog allergies, some of which are more problematic to deal with than others.
Have you ever stopped and observe your dog's behaviour? Do you take its scratching and biting as normal dog behaviour? Well maybe you should spend a little more time to see if your dog seems uncomfortable or show symptoms of dog allergies. Because many dog owners do not realise what allergies in dogs are like, many dogs suffer unnecessarily and some may even develop life threatening symptoms. Being a dog owner, you should get yourself educated and learn how to spot dog allergies.
Some good signs to look out for is redness of skin and itchiness. Does your dog seem to be scratching itself more than usual after you've changed the dog food to another brand? If so, chances are your dog has allergic reactions to the dog food, possibly certain chemicals present in the new brand. Then you should not use that particular brand of dog food. Fortunately, dog food allergies are relatively easy to correct since simply changing back to the old brand or to another brand would most likely stop the allergies in dogs. Comparatively, inhalant allergies are much harder for dog allergy treatment since there is a much wider range of probabilities to investigate and eliminate.
