My dog doesn’t like it when there are Things in the field.

We live in an RV park next to a large mowed field where dogs are allowed to walk. It's an open area and it's windy here often, so sometimes stuff from the park will get blown out there (think folding chairs, flower pots, etc).

My dog doesn't like this.

He's a roughly 5yo Pitt/acd/collie. When he sees stuff out there, even if they're just small things, he'll crouch down with his ears back and start trilling. If I let him go smell it, he creeps up and gets really low to the ground, sometimes gets his fur standing up. Once he determines it's "safe," he's good.

It hasn't been a "problem," per se but it's definitely interesting.
