This looks like the old labbie that lives down egrets way or around there somewhere. it often roams about and usually finds its own way home….if it is that one,… i also tried to rescue it a few months ago when it was hanging around Mr K’s, Peninsula superette. it does love a bit of food and is very friendly and quite fat if i recall correctly. There are a lot of doggies that live around Crickets / woodrow / egrets and otters that free roam.
please DO NOT take to spca as owners are likely at work
