For years, dog owners have panicked at the sight of their pets munching on grass, but experts reveal it could simply signal boredom or an ancestral behaviour. With Google searches for 'why is my dog eating grass' hitting their yearly high—20,000 searches monthly and a 177% surge over the past three months—specialists at natural pet food brand Forthglade have the answers dog owners have been seeking.
Vet Insights on Grass Eating
Brand ambassador and media vet Dr James Greenwood has offered his insights into why your dog might be eating grass and what signs to watch for. He explained: 'There is a common belief that dogs eat grass intentionally if they're feeling under the weather or to make themselves sick. But you might be reassured to know that eating grass is actually a really common behaviour we see in lots of dogs.'
They Just Like It
For most dogs this is probably the explanation. Dogs are omnivores and may simply find it tasty. 'It's very likely that dogs are eating grass simply because they like the taste of it, particularly during the spring and summer months, when grass is fresher and greener,' James said.
An Ancestral Instinct
James explained: 'Eating grass could be in their DNA and could be linked to their ancestral instincts, which can cause more of a natural pull to chew on things.'
Boredom or Lack of Stimulation
For certain dogs, eating grass might simply stem from a need for mental stimulation. 'Your dog may be turning to digging up and eating grass for more psychological reasons – perhaps because they're not getting enough mental stimulation or are bored. Trying a few enrichment activities, such as food puzzles or indoor games like hide-and-seek, may help. Your dog may also benefit from a more strenuous walk somewhere new or more socialisation with other dogs, perhaps at a doggie day care,' James added.
Need for Digestive Support
James said: 'Some worry that if their dog is eating grass it could indicate a problem with their nutrition, but, being omnivores, dogs need plant material to make up a balanced diet. Like humans, dogs need fibre in their diets to help digest their food more easily. If your dog isn't getting enough fibre, they may be turning to grass, which is a great source of fibre. Try adding a digestive powder to your dog's diet if you notice grass eating as a new behaviour, as this could fill their need for extra digestive support.'
When to Worry
James said: 'While there's no hard evidence linking eating grass to tummy problems, some dogs will vomit afterwards and it can give them worms. So if this is happening frequently, or there are other signs you're worried about, like notable weight loss, then it is worth checking in with your vet to ensure they are safely protected from things such as lungworm and that no underlying issues are causing them to eat grass.' Overall, though, the good news is that as long as your dog is well in themselves and there are no other signs of ill health, then there probably isn't really too much to worry about.
