Side-by-Side Stats

At a glance, the Cavalier King Charles Spaniel averages about 1.5 oz of waste per day compared to the Shih Tzu's 1.2 oz. Over a full year, that translates to roughly 34 lbs vs 27 lbs — a difference that compounds quickly, especially if you have more than one dog.

Which Breed Produces More Waste?

Which Breed Needs Professional Service More?
