Many dog owners worry when their pet starts munching on grass during walks, fearing it might be a sign of illness. However, a UK-qualified small animal veterinary surgeon, Catherine Henstridge, has clarified that this behaviour is usually normal and not a cause for concern.
According to Henstridge, studies show that less than 10% of dogs show any signs of illness when they eat grass. She explains that it is a natural behaviour observed in both wild dogs and wolves, and most dogs simply enjoy the taste. "It's not because they feel sick, it's not because they're trying to make themselves sick, it's just because they like it," she said.
Dogs Trust, the leading UK charity, adds that boredom can also be a factor. If a dog lacks stimulation, eating grass may be a way to entertain itself. The charity advises owners to provide enriching activities and avoid giving attention to the behaviour if it is attention-seeking. Instead, reward and praise other desired behaviours.
While small amounts of grass are generally harmless, excessive consumption can upset a dog's stomach and lead to vomiting. Dogs Trust recommends consulting a vet if the grass-eating is accompanied by symptoms such as eating other non-food items, refusing meals, changes in toileting, or vomiting.
