Fear, anxiety and stress come in many forms for our beloved canine companions. Whether it be the result of fearful experiences during the formative period of early life, anxiety from separation of siblings or family, or stress from loud noises and the disruption to normal life as a result of the pandemic, these emotional upsets can result in a seriously unhappy pet. But it is not just environmental situations and influences that create this negative state. Anxiety can also be passed down through family lines, and can be a normal aspect of evolution. Another major source of fear and stress is poor nutrition. As species diversity within the dog’s microbiome reduce, so too can behavioural instability increase. Gut dysbiosis is marked by an increase in behavioural volatility leading to a marked decrease in social amicability and domestic harmony. Calm not only provides a superbly balanced supply of essential nutrients that nourish the body and stabilise the mind, but actively supports microbial diversity within the dog’s environment. This results in a happier, healthier and more sociable fur child.
