Hearing constant distressed dog barking in my neighborhood, but can't find the source. What can I do in Amsterdam?

Hey everyone, I live in a neighborhood with a lot of apartment buildings, so I know that some level of noise is just part of city life, and I'm usually fine with it. But lately, the dog noise has gotten to a point where I'm less annoyed by it and more genuinely concerned that the animals aren't okay.

What I think is happening is that one or more apartments with small dogs are leaving them out on their balconies for long stretches of time. It happens at all hours - early morning, midday, even late at night. The dogs just bark, howl, and moan constantly, sometimes for 20-30 minutes at a time, and sometimes they set each other off. Honestly, it sounds like they're in real distress, not just being noisy, which makes me worry the owners aren't taking proper care of them. With the heat, I have to keep my windows open, so not only am I being woken up, but it's making it very difficult to focus while working from home.

The main problem is, I have no idea where the dogs are. They aren't my direct neighbors or even in my building. The sound echoes between the buildings and it seems to be coming from a couple of different places across two or three streets. If I knew which apartment it was, I'd at least try to leave a friendly note to start a conversation, but right now I'm completely stuck. So I thought I’d turn to Reddit for help. Is there any organization in Amsterdam, like an animal welfare group or organization, that can help when I can't even give them a specific address? Or has anyone experienced something similar and has some ideas on how to handle it?

I really love dogs and have no issue with them living here – occasional barking is totally fine. But this constant, distressed barking and sad-sounding howling just feels wrong, both for the neighborhood's peace and for the dogs themselves.

Any advice would be really appreciated.
