There are many reasons why dogs chew and bite their paws. They range from simple attention grabbing gimmicks to some potential health issue, parasitic infection, or allergic reaction. Some dogs indulge in this kind of behavior because they are smart enough to figure they can get the owners' attention by doing so. However, this is rare. Most of the time, chewing and licking the paw could be either because they have some kind of allergic reaction to some specific thing around them, specially the flooring they walk on. Another reason could be some injury to the region they chew and lick. A third possibility could be that they have a loose tooth, and just as we pull and push a tooth to pry it loose, they sometimes chew and lick their foot when they have bad teeth. There has have been recorded instances of such behavior and a similar diagnosis.
The most likely of these reasons is an allergic reaction or an infection. Whatever be the reason, instead of speculating about it, the best thing is to take your dog to a qualified vet as soon as possible for an examination, and let the vet ascertain the actual reason.
