Why do dogs eat grass and is it safe?

One habit that many dogs share is a love for munching on grass. But is it safe for them to do so, and should you stop them? Here, our vets in Nashua answer, 'Why do dogs eat grass?' and is it dangerous if you let them?

Why do dogs eat grass?

You're out on your evening stroll with your canine companion, and everything is going as usual when they suddenly stop and start chowing down on some grass. This can lead many pet owners to wonder things like 'Why my dog eats grass and '.

The good news is that grass-eating is pretty normal, and vomiting doesn't happen often after grass-eating. Most dogs eat grass without showing any signs or symptoms of stomach upset. So, it seems unlikely that dogs eat grass to induce vomiting. Then why do they do it?

Physical Causes

Some vets consider nutritional deficiencies a leading cause of dogs enjoying grass. Grass can also be an excellent source of fiber for your canine companion. 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.

While less common, gastrointestinal issues can occasionally cause a dog to spend some time chewing on grass. Dogs can suffer from stomach and gastrointestinal issues, including 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 an examination.

Psychological Causes

You may find that your dog is not physically wrong and is just plain bored. If you catch your dog chomping away in your yard but don't show any signs or symptoms of health issues, they may just be looking for something to do. 

You could try bringing your pup out for longer walks or more interactive playtime to curb this grass-eating behavior.

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

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