Do you remember the white dog droppings from the past? They used to be a common sight on lawns and sidewalks, but today they have almost completely disappeared. This is not only because more people are cleaning up after their dogs. The key reason lies in the dog bowl.
Why Dog Poop Used to Be White
Those who recall the white dog droppings of past decades often think of a neglected cityscape. But there was a clear reason for the very noticeable color: the food. Back then, dog food contained much more bone meal than it does today. This ingredient led to an above-average calcium intake. However, dogs’ bodies could only process part of the calcium–the rest was excreted, turning the poop white. The consistency of the droppings was also correspondingly crumbly.

The feeding of dogs has changed significantly over the past decades. Dog food today is of much higher quality than it used to be. Bone meal, once a cheap and common component of industrial pet food, is now considered outdated and is no longer used in high-quality food. Too much calcium in the food can not only lead to white poop but also pose health risks–such as kidney stones or unnatural calcification of the bones. 1

Exception: BARF Feeding with Bone Supplement
The bone meal was mainly found in dry food. Today, many dogs are fed a mix of wet and dry food or a similarly high-quality diet.
However, bone meal has not completely disappeared. In the so-called BARF diet–which is based on raw meat, offal, and bones–it is deliberately used as a dietary supplement.
This involves a targeted intake of calcium, phosphorus, and vitamin D. However, this is a targeted supplementation, of which the dog needs only a few grams per day. With the correct dosage, the dog’s poop should not turn white.
When White Poop Is a Warning Sign
If a dog excretes white poop without having eaten bones or bone meal, it can be a sign of health problems. It could indicate impaired fat digestion or an infection. However, in such cases, it is more likely to be whitish pus or foam rather than the consistency of dog droppings that many still remember from the past. In such a case, a veterinarian should be consulted for clarification.
