There are 2 barking dogs one on D Street one on E Street NE they are both visible from the alley behind 423 18th st NE
The white dog on E street NE is always out side I've never seen him not in the back yard. I'm not sure if the owners ever see this dog I've seen others in the neighborhood feeding the dog and I've left water for him in the summer when it was so hot out. He does go into the back porch but he barks outside 24 hours a day and is a very friendly dog I think it's just so lonely.
The other dog is a large great dane type dog that in the past has been outside only when it's owner was home but now he's being left out on the back patio in what looks to be a dog crate (this is a huge dog) and it's is always barking and crying. It's on a 2nd floor balcony so I can only hear it.
