i just try not to think about it too much honestly. if i go to the enclosed dog park with Luka i make sure i watch him at all times just like i would if i had a child playing at a playground. on walks i keep a firm hold of his lead and if someone were to take him they'd have to pry my dead fingers off of it first. Lastly, like everyone else has mentioned i make sure he's chippped, that it's updated at all times, and he also has his tag with my information. I also went ahead and put his microchip tag on his collar because if the vets are closed someone can call the number on it and they will give them my information.
