why do small dogs run away and get lost

Are there Coyotes in your area?
They are known to prey on small pets.

Also: No one wants to admit when their pet is really stupid.

Any dog is capable of running away for many different reasons. Like Shogun said, the smaller ones may get eaten more, and a lot of the bigger ones are stolen for a variety of reasons. Check local lost and found pet groups on social media and you will find all types of animals, and breeds.

A lost dog makes me SO sad.

Because they are small...

I’ll pm you a funny story about that

Their size makes escape easier, that's all. Big dogs can't slip through a crack in the fence or dig a hole big enough to escape through before it gets noticed usually.

They get spooked easily by loud, sudden noises then dash off in a panic. I’ve seen flyers for lost Labs, but they usually bust thru a backyard fence. My hound knocked a couple panels out of our fence and went into the neighbor’s yard. Luckily she was sniffing around their yard when I found her.
