Stray dog Carrick-on-Suir

There's a black lab wandering around Carrick-on-Suir for about the last week or so.

He is a very blocky, strong looking boy but he is quite timid and friendly and seems to be very hungry.

He has something on his front right leg but it looks to me like dirt stuck to his coat as opposed to a sore.

He has no collar on him but his coat seems to be in good condition and he doesn't seem to have any obvious health problems aside from probably being very hungry and thirsty.

Does anyone know anything about this dog? I have pictures of him on my phone but I can't put them up here until I get home.

I have this morning contacted a person in Cottage Rescue (I sent the picture of the dog via text) and I am waiting to hear back from them. The reason why I did not contact the TSPCA is because it says on their site they keep dogs for 5 days only.

If anyone has any suggestions on what else I can do I'd really appreciate it as he seems like a lovely dog who is either greatly missed by his family or in need of a new loving home.

Thanks in advance.
