Dogs are by their nature scavangers and will take every opportunity to have a free meal whenever possible.
Although a seemingly strange choice, most dogs enjoy a chomp of grass every now and then and, most likely, enjoy the taste and smell – something which, as humans, we cannot appreciate.
Many people suggest that dogs eat grass to make themselves sick when they are unwell, and, although some dogs will vomit after eating grass, there is no evidence to support the suggestion that dogs are intelligent enough to consider that eating grass is a cure for illness.
