Friends in my street adopted Lewis from the RSPCA when he was about 4 years old. No-one knew his past history but he’d had a bad time as he was aggressive towards strange men. The young couple (his new family) both worked long hours and he was left at home. He suffered from separation anxiety so tried to escape their yard most days. Often I would see him “setting out” on an adventure along the street and I’d go after him. He loved this and turned it into a game I’m sure.
