Is your dog's grass eating a cause for concern?
Q; My 18-month-old Border Terrier eats grass, which he brings back up. He seems fine afterwards. Why does he do this?
A: This is fairly normal behaviour in many dogs, and it's thought that they do it to get nutrients lacking in their daily diet or to stimulate vomiting to help clear the gut of toxins. If your dog's stools are of a normal colour and consistency and he usually eats well without vomiting, then I wouldn't worry too much. If the regurgitation becomes more severe or he loses weight, then changing his diet to a 'sensitive' formula may help calm his gut and avoid the need for his lawn-mowing antics.
