I’ve always preferred to keep dogs on a leash when walking to ensure they don’t run off unless they are trained well or have a fenced in area. Even if they are off-leash in your personal yard or a dog park, I’m always right there watching them. I’m used to entering houses and blocking animals from running out the door on me. I’m comfortable with giving medications whether it’s an injection, wrapping a pill in food, mixing it in their food, or having to give it directly in their mouth. I’m aware of the environment to look for any signs of sickness or stress from the animals.
