Some owners tend to just focus on the back, assuming that this is where most of the dead hairs are coming from. While this is certainly the largest area of fur, hairs will fall from every body area other than the mask, the under-belly and of course, where there is only leather (paw pads, nose).
To really stop shedding issues, be sure to brush the entire body - head, neck, legs and even under and top areas of the tail. Pulling out dead hairs from all of these areas will greatly cut down on the amount of hairs that fall to the ground and is an important part of controlling the heavy shed.
The coat of a Pug is not long , but it is
very dense. The best way to brush a Pug is to use long strokes that gently reach down to the skin. You will want to brush in the direction of the fur growth. Be sure to not just skim over the coat; a good majority of the dead hairs become trapped in the thick coat.
As you brush, go deep enough to gently brush to the skin, pulling out and away at the end of each long stroke.
