Popular anecdotes suggest that our four-legged friends like to eat grass to purge. The latest research, however, offers alternatives to this widely held theory. So let's take a look at what's really behind this mysterious behavior.
Unmasking the myth: The unexpected reasons behind grass nibbling in dogs
“If you share your life with a dog, chances are you've seen him eat grass before.
But why does he do it? For a long time, we believed in a kind of canine self-therapy, where our pets consumed grass for self-purification. However, new studies challenge this popular belief and point to two other possible reasons.
Rest assured, these new reasons are not alarming. On the one hand, our canine companions may be eating grass to compensate for a lack of certain nutrients in their diet, notably fiber. On the other hand, and quite surprisingly, they may simply like the taste of grass.
A natural behavior: Do dogs really like to eat grass?
“Sometimes we can see our dogs enjoying the sun, lying in the grass while nibbling on a few blades.” This could indicate that they really enjoy this behavior. There's no reason to prohibit it, provided they don't consume toxic vegetation and the area hasn't recently been treated with herbicides.
Debunking old assumptions: Do dogs eat grass to vomit?
Several studies contradict the idea that dogs eat grass to induce vomiting. For example, a study conducted by researchers at the University of New England in Australia analyzed the behavior of 12 grass-loving dogs. The aim was to check whether the dogs vomited after eating grass. The results? In most cases, nothing happened. What's more, only 25% of the dogs tended to vomit after eating grass, suggesting that this was not a purging mechanism.
Lack of nutrients: Grass, an unsuspected source of fiber?
It's possible, however, that our canine friends seek to compensate for a nutrient deficiency by eating grass. An interesting case is that of a poodle who, after being fed a high-fiber diet for seven years, stopped eating grass. This suggests that the dog may be compensating for a lack of fiber in its diet by turning to grass.
The wild instinct: A taste for grass encoded in dog DNA?
Dogs may have a taste for grass because of their genetic heritage. According to a study carried out in Yellowstone National Park in the USA, 74% of wolf droppings analyzed contained remnants of grass. So it could simply be that our four-legged friends enjoy chewing grass.
When to worry Precautions to take
Where your dog nibbles his grass is crucial.
Make sure the area hasn't recently been treated with herbicides and doesn't contain toxic plants. Indeed, while we can't always control these elements in a park or field, we can check with local authorities or make sure they don't occur in our own garden.
Finally, let's not forget that to take care of our four-legged friends, we also need to learn a little about botany. After all, they'd do it for us if they could, wouldn't they?
