Advice on new dog

Just adopted a dog on Friday.
Today, I knew I would be gone all day, so I left it in the fenced back yard with its food and water. When I got home, there was a handwritten note on my front door complaining about the dog’s incessant barking, stating that if this dog is not just a weekend guest, that it better be an inside dog because they won’t put up with it. The neighbor didn’t sign their name, so I don’t know which neighbor it was.


When I got in the backyard, I saw what I think may be why: his water bowl was completely empty. He must have drank it all and was barking for someone to bring him more. When I brought him inside, he drank a ton, and was clearly very thirsty.

I work a standard 9-5 office job. So, for tomorrow do I:
1. Leave the dog inside and worry about it chewing or eating things and pissing all over the place unsupervised; or
2. Leave the dog outside and worry about it barking too much, causing a complaint which could lead to me being forced to give up the dog;
3. Force it to stay in its kennel all day inside

When I’ve been home, the dog rarely, if ever barks, but one neighbor’s dog barks at it constantly if they are both outside at the same tome.

The whole reason I got this house was because it had a big fenced in yard for a dog to live in. But, in my lease, complaints against me to the neighborhood association could get my lease voided.

What would the OT do?

Note: This is a good-sized high energy dog (Aussie) that needs exercise.
