Why do dogs like to chew slippers?

Dogs tend to chew anything at hand as we mentioned previously, so it is not strange for us to think about why dogs like to chew slippers. They do it because they like to chew and because slippers are usually made out of soft materials that they can actually fit in their mouth and play with. I'd rather think the smell and taste has nothing to do, but it probably does. When we think about this matter we must recall that we are half responsible for this behavior as we are the ones who ask them to retrieve these kind of things when at home. Dog trainers also use similar objects to make them learn how to retrieve. Cute aren't they?
