Many dogs will snack on grass and it’s a bit of a mystery as to why they do that. Dogs often vomit after eating grass. The question is whether eating the grass makes them feel bad so they vomit or did they already feel bad and ate the grass to vomit and feel better? There is the theory that dogs eat grass because their diet is lacking in certain nutrients that the grass provides. Some dogs seem to eat grass because it tastes good to them. Thus you may not be able to stop your dog’s grass eating. However, watch your dog when outside to keep him from eating too much grass. Most importantly, take care that your dog doesn’t eat grass that has been treated with pesticides or fertilizers that could harm your dog. Use pet-safe products instead if possible.
