Vet Dr James Greenwood has shared his expert advice on why dogs eat grass, a behaviour that prompts 20,000 Google searches per month with a 177% increase over the last three months. The natural pet food brand Forthglade's brand ambassador and media vet explains that this common behaviour is usually not a cause for concern.
Why Dogs Eat Grass
Dr Greenwood says there are several reasons, starting with taste. Dogs are omnivores and may simply enjoy the flavour, especially in spring and summer when grass is fresher. He states: “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.”
Another reason is ancestral instinct. “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,” Dr Greenwood explains.
Boredom and Stimulation
Boredom can also drive grass-eating. Dr Greenwood notes: “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.”
Digestive Support
Some dogs eat grass due to a need for extra fibre. Dr Greenwood explains: “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
While grass-eating is generally harmless, Dr Greenwood advises caution. He says: “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.”
