Is Maryck in Jamaica here? About your dog...?

Your question has been deleted, possibly because someone thought it was an attempt to troll (which I hope it is, but...).

I wrote this in answer right as it vanished. If you truly do need the help, I hope it is useful.

Even if there are no municipal animal control facilities, I found this http://www.theanimalhousejamaica.org/ and perhaps there are others (Google animal services Jamaica or similar)... possibly one of these agencies will know who could help you or be able to help themselves.

I cannot imagine...

If you do have a local vet, you could call and see if they would send someone to euthanize your dog at home and allow you to work off the cost by cleaning cages or something.
