I saw 22 or more plane-like lights flying north-east in a straight line, my dogs were acting strange during it.

I was outside letting my dogs out at 8:00 at night (at home) when I saw how clear the sky was. I have an addiction to watching stars on clear nights, waiting for a meteor. I was looking around at all the stars and constellations when I turned somewhat northwards. When I saw the first two, I simply thought they were lanterns.
But then I saw the next four, and I knew it could not have been lanterns because they were in a straight line. These lights were not equally spaced, so I do not believe that they were satellites.
My dogs were acting quite odd as well. They were facing in the direction the lights were coming from, the older one was whimpering, and the younger one was growling. I counted about 19 of the lights before my older dog suddenly turned around and started barking at the cars across the street. I looked and got as close as I dared, but I didn't see anything. No movement and no sounds came from the direction of the cars. By that time, I was getting uneasy. All together I counted 23 lights, but they were still coming. I got my dogs in the house but I couldn't shake my uneasiness.
