Why do dogs eat grass?

Let’s face it: dogs can do weird things sometimes. They lick the couch, bark at random plastic bags and always - I mean always - forget that the glass door needs to be open in order to walk through it. When eating grass becomes part of their ‘weird’ habits, you start to wonder… Why do dogs eat grass?

It’s actually a common behaviour that baffles many dog owners, so don’t worry, you’re not alone! We’ve had our fair share of waiting around freshly sprung grass while Muppet casually downs several mouthfuls of greens. But why do they do it?

We did some research on the topic and here’s the ugly truth: no one’s 100% sure. It’s likely there’s not one simple answer. Different dogs may eat grass for different reasons, but understanding why your dog does can help you address the behavior.

It’s tasty

Your dog eats every single crumb he can find on the kitchen floor so why stop there? As natural scavengers, dogs are programmed to search for nutrition. Do you often find your pup hunting for the right blade to nosh on? It’s possible that your four-legged friend finds the flavour or texture of grass yummy. Or it could be filling nutritional needs that his normal food isn’t.

If you think this might be the case, make sure to consult with your veterinarian before making any changes to your dog’s diet!

He’s bored

Dogs chew things frequently when they’re bored and need 'something to do'. One day it’s your slipper, next it’s the dining table and on the rare occasion that your dog’s got the backyard to himself, it’s eating grass. Do you notice your dog eating more grass during times when you aren’t walking or playing as often?

Sometimes the solution can be as simple as providing a chew toy or puzzle as an alternative or introducing a more consistent exercise routine. Here are some of the best dog toys to keep your furry friend busy and mentally stimulated! 

Stomach distress

For the same reason why cats eat grass, some dogs might turn to greens when they have tummy troubles as a way to make themselves throw up and then feel better. This form of self-medication is more likely if the behaviour starts suddenly or if your dog is suddenly very anxious about needing to eat grass. 

Have you noticed a sudden increase in grass grazing? Stomach distress can be a sign of a more serious underlying illness - call your vet for advice! 

Still not sure?

Relax! Many veterinarians consider grass eating a common dog behaviour, so don't panic, your dog is (mostly) normal, even if he/she loves some salad every now and then. 

While dogs don’t gain any real nutritional value from grass, it also may not hurt them - as long as there are no dangerous fertilizers, pesticides, or herbicides used on the grass itself. 

You can help protect your furry friend by using only non-toxic products on your own lawn or providing a safe alternative by growing a grass or herb garden specifically for him to snack on.

When in public, make sure keep an eye out for signs warning that chemicals have been used on the grass - if not, your little grass eater will be just fine!
