Why is my dog eating grass?

Have you ever noticed your fluffy friend nibbling on your freshly manicured grass?

Dogs eating grass is not exclusive to domestic dogs and is a behavior that has been observed in various settings. A study conducted at Yellowstone National Park in the United States found plant matter, primarily grass, in almost 75% of wolf feces. While this behavior is not new, it tends to catch the attention of dog owners. Up to 80% of dog owners have noticed their dogs eating grass on their grass or while visiting local parks. So, why do dogs eat grass, and is it beneficial for them?

Why does my dog eat grass?

The common belief that dogs eat grass when they have an upset stomach in order to induce vomiting is not entirely accurate. Most dogs eat grass without subsequently vomiting, and when they do vomit, it is typically right after a meal. In fact, dogs with an upset stomach are less inclined to eat grass compared to when they are feeling well. Other theories suggest that dogs eat grass as a mild laxative or to add roughage to their diet. However, there is no substantial evidence to support these claims.

A study involving 12 dogs with no previous digestive issues or worm infestation demonstrated that they happily consumed grass. Your fluffy friend may be eating grass simply because they enjoy it. It could be an activity they find entertaining when they are bored. The study also found that dogs were more likely to eat grass if they hadn’t eaten their regular meal yet. So, your dog may just be hungry!

Risks associated with dogs eating grass.

There are several reasons why you might not want your fluffy friend to consume your carefully manicured grass. One significant concern is that grass are often treated with herbicides. As a dog owner, you cannot always be certain if someone has recently sprayed their grass. Many local councils use a non-toxic dye to mark areas where herbicides have been applied, which is helpful. However, we still recommend exercising caution. Herbicides and grass sprays can persist in the grass for up to 48 hours after application and have been found in dogs’ urine. Studies have also suggested a potential link between exposure to grass sprays and bladder issues in dogs.

When treating your grass with herbicides, it is essential to remove your dog, their toys, food, and water from the area before spraying. Before allowing your dog to return, ensure that the chemicals have completely dried out. We strongly advise checking the package for the drying time of each pesticide and herbicide.

Some dog owners opt for hand weeding as a safer alternative for their dogs. At Capalaba Produce we have a variety of pet safe, fertlisers such as Earthlife Lawn Blend, we also have a wide range of pesticides and herbicides. Ask our friendly team in store!

Another risk of dogs eating grass from your grass is the potential toxicity of leaves, flowers, and berries that may be present. Common plants like oregano and bay leaves can cause vomiting and diarrhea in dogs.

The final risk which we are going to talk about today is worms. Because of how parasites transfer to your dog we suggest giving your dog a preventative for worms and parasites such as Nexgard Spectra.

So, should I allow my dog to eat grass?

One of the best things you can do is take your dog for a walk. If they happen to consume grass that has not been treated with herbicides, pesticides, or fertilizers, there is generally nothing to worry about. Dogs can sometimes vomit up grass with a yellowly fluid (bile) this is usually because they have recently eaten food, not because of the grass. However, if your dog starts vomiting or experiencing diarrhea, we strongly recommend consulting your local vet.
