I would second animal action is they rescue a lot of dogs and only have a small group of volunteers.
If you have any sighthound-suitable collars (wide collars or martingale collars) then ASCOD would put them to good use!
Animal Action was asking for dog collars just today and I am sure they would appreciate the rest too. Please check with them on their facebook page - if you are in Dubai you could probably drop them off at City Vet and someone from their group could probably collect from there. :)
