No, she just complete ignore those balloons, who are airlifted evry summer from the park, across the street. They actually come over with a very low altitude. But as i alreayd said .. She dont even noticed them, even when she is near themDoes Laika bark at them?
There's a balloon club locally with many members and many balloons and they have a number of launchings from the soccer fields adjacent to the nature preserve where Puff and I walk every morning.
When they lift off and are burning their gas jets to make more hot air, Puff barks as if they were aerial intruders she needs to warn against or frighten away.
