Same with many other animals in the area...
Maybe he smells a predator? Lots of them around these days.
I was wondering about a bit further afield. Like a friends place across town, or out in the boonies.
I have a rat terrier which is like that in that he wants in immediately after being let out to take care of business.
On the other hand, my daughters Yorkie-poo hasn’t the sense to come back in unless we go out after him and this is after he was attacked by a coyote a year ago.
The only things which saved him were the fact that he was tied up to a long leash and my wife heard the commotion when the coyote grabbed him and was there to immediately scare the coyote off.
