I'm actually on Nextdoor ♡ but I did not post him on it. Good idea!There's an ap called Nextdoor that I've used to find dog owners. It doesn't always work but sometimes does! And one time when we had a starving dog show up, we were able to find a rescue group to take over her care through it.
The thing with these hunting dogs is they can come from anywhere on the island and depending on how much their parent loves them reflects how fast then can be found- with exceptions of course. Sometimes the dogs can be wounded and lost for months b4 they surface and for some owners they may have lost hope or moved on. This guys best bet if for his person to connect. Because these dogs can be so isolated and loyal (like a captive) to one person it is near impossible to capture... takes lots of time.
This morning I put his food out early by our outside water dish which is close to our lanai gate. After a day or so, I'll open gate and put food on lanai. This will be and inconvenience for me and the cats but worth a try to get this boy "off the streets"
