Bullmastiff vs Rottweiler: Waste, Diet & Cleanup Compared

Side-by-Side Stats

At a glance, the Bullmastiff averages about 11 oz of waste per day compared to the Rottweiler's 10.3 oz. Over a full year, that translates to roughly 251 lbs vs 235 lbs — a difference that compounds quickly, especially if you have more than one dog.

Which Breed Produces More Waste?

The Bullmastiff produces significantly more waste than the Rottweiler — roughly 1.1x as much daily. That 16-lb annual difference means Bullmastiff owners deal with considerably more yard cleanup.

Body weight is the primary driver of waste volume. The Bullmastiff averages 115 lbs compared to the Rottweiler's 108 lbs. Dogs generally produce waste equal to roughly 0.5–0.75% of their body weight each day, so larger breeds invariably fill the yard faster.

GI Issues & Digestive Health Comparison

Understanding each breed's digestive vulnerabilities helps you know what to watch for during yard cleanup. Changes in stool color, consistency, or frequency are often the first visible sign of a health issue.

Bullmastiff: Bullmastiffs are powerful guard dogs with proportionally large waste production.

Rottweiler: Rottweilers are powerful dogs with large appetites and proportionally large waste production. A single Rottie can produce over 400 lbs of waste per year.

Cleanup Difficulty & Recommended Frequency

Cleanup difficulty depends on waste volume, frequency, and yard behavior. Here's how these two breeds stack up:

• Bullmastiff: Moderate-High difficulty — 2–3 poops/day, moderate activity level, moderate shedding
• Rottweiler: Moderate-High difficulty — 2–4 poops/day, high activity level, moderate shedding

These gentle guardians deserve a clean yard to patrol.

One Rottweiler's annual waste output exceeds most people's expectations — professional cleanup is practically required.

For the Bullmastiff, we recommend weekly service. For the Rottweiler, weekly service is ideal. If you have both breeds, go with the more frequent schedule to stay ahead of accumulation.

Which Breed Needs Professional Service More?

Between the two, the Bullmastiff benefits more from professional pet waste removal. At 251 lbs of waste per year, DIY cleanup becomes a significant time commitment — especially combined with the breed's moderate activity level and moderate shedding.

That said, Rottweiler owners also benefit from professional service. Even at 235 lbs annually, keeping up with 2–4 daily deposits requires consistency that's hard to maintain.
