English Mastiff vs Bullmastiff: Waste, Diet & Cleanup Compared

Side-by-Side Stats

At a glance, the English Mastiff averages about 16.8 oz of waste per day compared to the Bullmastiff's 11 oz. Over a full year, that translates to roughly 383 lbs vs 251 lbs — a difference that compounds quickly, especially if you have more than one dog.

Which Breed Produces More Waste?

The English Mastiff produces significantly more waste than the Bullmastiff — roughly 1.5x as much daily. That 132-lb annual difference means English Mastiff owners deal with considerably more yard cleanup.

Body weight is the primary driver of waste volume. The English Mastiff averages 175 lbs compared to the Bullmastiff's 115 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.

English Mastiff: Mastiffs are the heaviest breed and produce truly massive daily waste. A 200 lb Mastiff can produce over 600 lbs of waste per year.

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

Cleanup Difficulty & Recommended Frequency

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

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

At 200+ lbs, your Mastiff produces more waste in a month than most dogs produce in three.

These gentle guardians deserve a clean yard to patrol.

For the English Mastiff, we recommend twice-weekly service. For the Bullmastiff, 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 English Mastiff benefits more from professional pet waste removal. At 383 lbs of waste per year, DIY cleanup becomes a significant time commitment — especially combined with the breed's low activity level and moderate shedding.

That said, Bullmastiff owners also benefit from professional service. Even at 251 lbs annually, keeping up with 2–3 daily deposits requires consistency that's hard to maintain.

• Higher number of breed-specific GI issues (3 known concerns) means more waste irregularities to manage
• 383 lbs of annual waste takes roughly 7 minutes per week to clean manually
