Fear and anxiety are a common cause of behavioural problems in most dogs, and greyhounds are no exception. Many greyhounds have not experienced the typical day-to-day sights and sounds, or activities that companion dogs are accustomed to. As a result, it can take a while for your average retired greyhound to grow comfortable in their new home. While they are adjusting, it’s common for a greyhound to experience some fear/anxiety as they encounter all the new things in their world.
