How Much Does a Bulldog Poop?

Quick answer: an adult Bulldog weighs 40 to 50 pounds and produces roughly 3.8 to 7.7 ounces of stool a day on dry kibble. That is about 2.2 to 4.5 ounces per pile, and 87 to 176 pounds a year.

How we worked that out

How much a dog produces tracks how much it eats, and how much it eats scales with body weight, but not in a straight line. Vets estimate a dog's daily energy need as 70 times its weight in kilograms raised to the 0.75 power, which means small dogs eat more per pound than big ones, and so produce more per pound too. We ran each breed's weight range through that formula, divided by the energy in typical dry kibble, and applied the measured ratio of stool to food eaten. As a check, the model predicts 62 to 105 grams a day for a 19 pound beagle, and lab beagles of that weight on kibble measured 90 grams.

For a Bulldog, that comes to about 0.58 to 0.99 percent of body weight a day. How often a dog goes does not really depend on breed. Most adult dogs go about once a day, and two or three times is normal (PetMD). Diet and fiber drive frequency far more than breed does. So a big breed does not need more bags than a small one. It needs bigger, tougher ones.

Diet moves the numbers a lot. In one study of lab beagles, dogs on fresh cooked food produced about 38 percent less stool than on kibble, and dogs on raw diets about 56 to 59 percent less (source). Every figure on this page assumes dry kibble.

What Bulldog owners should know

Brachycephalic GI signs: 58% of English Bulldogs referred for brachycephalic airway syndrome had gastrointestinal signs (regurgitation, vomiting, ptyalism). (source)
Skin fold dermatitis: English Bulldogs had the highest odds of any breed (OR 49.07 vs crossbreeds), including frequent tail-fold dermatitis around the screw tail. (source)
UK primary-care study of acute diarrhea (2019): English Bulldogs OR 0.55 (95% CI 0.29-1.03) vs crossbreeds, not statistically different. (source)

Any sudden change in your dog's stool, especially with vomiting, lethargy or blood, is a reason to call your vet rather than wait. Our dog poop color chart covers what the common changes can mean.

Cleanup with a Bulldog

Screw tail and tail pocket: UK data show frequent tail-fold dermatitis in English Bulldogs. Wiping the tail fold after defecation is part of cleanup for this breed.

How the Bulldog compares

Of the 60 breeds we covered, the Bulldog ranks #29 for daily output. Here it is beside the breeds closest to it in size:

Breed	Adult weight	Daily output
Border Collie	30 to 55 lb	3.1 to 8.3 oz
Australian Cattle Dog	35 to 50 lb	3.5 to 7.7 oz
Bulldog	40 to 50 lb	3.8 to 7.7 oz
English Springer Spaniel	40 to 50 lb	3.8 to 7.7 oz
Siberian Husky	35 to 60 lb	3.5 to 8.8 oz

What that means for the bag

For a Bulldog, thickness matters more than size. You want a bag you cannot feel warmth through, with enough length left over to tie off cleanly.

For your own number of bags, the bag quiz gives it to you, and how many poop bags you need shows the math.
