Q: Why does my dog eat grass?
A: Dogs eating grass is a common behaviour for many canines. While the exact cause does vary from dog to dog and situation to situation, the most common reasons are as follows:
- Natural instinct: Dogs are omnivores by nature, and their ancestors likely ate grass or plants as part of their diet. Eating grass could be a remnant of this instinct.
- Looking for fibre: Grass contains fibre, which may help with digestion. If your dog’s diet is low in fibre, they might turn to grass as a supplement.
- Nausea: Some dogs eat grass when they feel nauseous. The grass may induce vomiting, helping them get rid of something in their stomach that’s bothering them.
- Boredom: If your dog isn’t getting enough mental or physical stimulation, they might nibble on grass out of boredom.
- Curiosity: Puppies, in particular, may chew on grass while exploring their environment.
- Enjoyment: Some dogs simply enjoy the taste or texture of grass.
- Self-soothing: Eating grass can be a self-soothing behaviour for dogs feeling anxious or stressed.
When to call your vet
Grass eating is usually harmless, but there are times when you should take notice. For instance, if your dog is eating grass and vomiting regularly, which suggests gastrointestinal issues, or if your dog seems to be obsessively eating grass, which suggests anxiety, you should call your vet. If grass eating is a regular occupation for your pup, you could also chat with your vet about possible dietary changes that might improve the situation.
NOTE
Grass treated with chemicals, pesticides, or fertilisers can be toxic to dogs. Always ensure your dog’s grass source is safe.
