I live in a pretty to a very safe area in the USA. My backyard is large, grassy, and safe (no manmade objects, choking hazards, poisonous plants, etc.) so I let my puppy be in the fully fenced in the backyard unsupervised while I am inside.¹
However, my back fence is short (around 3-4 feet / 0.9-1.2 meter tall) and I worry someone will hop it and steal my puppy from the backstreet behind my house and backyard. My puppy is a breed on the expensive side, so I worry that someone will see a chance to steal him and sell him to make a lot of money.
My fear is probably unwarranted as like I said, I live in a pretty to a very safe area that has a tight community to it.
But it's always better to be safe rather than sorry, so this leads me to my question:
Should I worry about this? If so, what can I do to prevent it?
¹I do not leave my puppy unsupervised for long periods of time. At max, they are unsupervised in the backyard for 30 min.
