Dogs love their 'Almond Rocca'...

Pick up their stools and keep the litter pans cleaned up as quickly as possible.

Add a sprinkle of Accent flavor additive to their wet food (or moistened dry) daily for 3-4 days, that may help break them of the habit.b

If you can, you may find that these prblem go away once you switch your dogs over to meat only, ideally raw meat diet.

To me that's an inidcation they are missing something in their diets and feeding as natural and species specific as possible is usually healthiest for any critter :-)
