Veterinarian Nicole Rouse has shed light on the four most common reasons why dogs may indulge in a spot of grass-munching. While this behaviour is observed in most canines, pet owners often leap to incorrect assumptions about its significance.
In a TikTok video, Rouse, who posts online as @drnicolerou.vet, outlined the potential explanations behind this common canine habit. The first is simple boredom or curiosity, as dogs are naturally inquisitive creatures and may investigate their environment by nibbling on what’s around them.
Another potential reason stems from their ancestral past, as Rouse suggests this behaviour “may stem from their ancestors, who consumed plant matter as part of their diet, potentially in search of extra fibre.”
However, the two explanations that tend to cause the greatest concern among pet owners are an upset stomach and nutritional deficiencies. “One reason that concerns many pet owners is that some dogs eat grass to soothe an upset tummy or to induce vomiting,” Rouse explained. “If your dog frequently eats grass and seems uncomfortable, it’s important to consult your veterinarian.”
She also highlighted that dogs may consume grass, or even soil, while seeking trace minerals they might be missing from their diet. Rouse’s general guidance is that “if your furry friend only occasionally nibbles on grass and is otherwise healthy, there’s usually no need to worry. But if grass-eating becomes a frequent habit, a chat with your vet is a wise step.”
The responses to Rouse’s post on TikTok further illustrate the varied reasons behind this behaviour. One user revealed that their German Shepherd eats grass as part of a routine when swimming in the pool, while another shared that their Jack Russell does so to soothe an inflammatory bowel disease. A third user simply stated that their dog “just loved the taste” of buffalo grass, despite having a balanced diet and good health.
Ultimately, Rouse’s insights provide a valuable perspective on this common canine quirk, helping pet owners understand when it’s simply a harmless curiosity and when it may be a sign of an underlying issue that warrants a visit to the vet.
