Dogs Eating Grass: Why Do They Do It & Is My Dog Poisoned?

Many dog owners are unsure as to why their dog is eating grass. Here, our Elk Grove vets discuss why your dog may be eating grass, and how it affects them.

Why Dogs Eat Grass

Pet parents are often left confused as to why their dog seems to enjoy eating grass. Many dogs will eat grass, vomit, and then go right back to eating grass again.

Could this imply that your dog isn't feeling well and wants to get something unpleasant out of their stomach? Have they gotten into something poisonous? Is your dog drawing attention to an undiagnosed medical condition? 

Some dogs do vomit after eating grass, but that's not the case for all dogs. The majority of dogs eat grass without showing any signs or symptoms of an upset stomach. So it seems unlikely that dogs eat grass to induce vomiting. Then why do they do it?

Psychological Reasons Why Dogs Eat Grass

Boredom and anxiety can play a role in your dog's grass-eating habit in the same way that people with anxiety bite their nails. If your dog doesn't show any signs of digestive issues but eats grass like there's no tomorrow, psychological reasons should be considered for the behavior.

If your dog could simply be suffering from boredom, increasing the length, distance, or intensity of walks could help to reduce grass eating.

Separation anxiety could also be the reason that your dog is eating grass. Try leaving an old blanket or t-shirt with your scent on it with your dog when you leave the house. Your dog may find the familiar scent reassuring and help to curb their grass-eating habit. 

Some dogs show obsessive behaviors. If your dog is obsessively eating grass, your vet will be able to advise you on how to help your pooch reduce obsessive behaviors.

Physical Reasons Why Dogs Eat Grass

Dogs need the right amount of fiber in their diet to keep their digestive system moving properly. After all, dogs are omnivores, so their good health depends on plants as well as high-quality meat. Eating grass may be an easy way for your dog to add roughage to their diet, helping to keep things moving through their digestive tract.

That said, if your dog is eating grass but also showing signs of stomach upset, there may be a medical problem. Dogs can suffer from several stomach and gastrointestinal issues including conditions such as pancreatitis, and inflammatory bowel disease. If your dog is eating grass and has other symptoms such as lack of appetite, decreased energy, diarrhea, or constipation, it's a good idea to take your pup to the vet for a wellness exam.

How Eating Grass Impacts Dogs

If your dog is otherwise healthy and on regular parasite prevention medication, eating grass is considered to be a safe behavior.

To help keep your grass-nibbling pooch healthy, make sure that there are no herbicides, pesticides, or fertilizers on the grass your dog enjoys.
