Sometime ago I posted what to do if you find a lost dog. Today I found out that there is another option.
Tips on How To Report a Lost or Found Pet
About 9:30 Saturday morning a Border Collie turned up on our driveway. He had a collar, but no id tag. I didn't know the dog, but thought he might be from the area, so we tried to call both vets nearby, no one answered. We called the Tierschutz in our Kanton and they said we could bring the dog to the shelter. We just were not comfortable transporting the dog who was so friendly but still nervous so we called the "TierRettungsDienst".
www.tierrettungsdienst.ch
They have a 24 hour number 044 211 22 22
They said someone would come with a microchip reader, so we waited with the dog. In the meantime we asked everyone who passed our house if they knew who the dog belonged to and we called all possible leads but it wasn't anyone.
When the volunteer from the Tierrettungsdienst arrived, she too commented on what a lovely dog he was, and that surely he belongs to someone. Fortunately he had microchip, and she then called ANIS in Bern and they contacted the owner, gave her the details as to where the dog was found and so we all waited for her. We also found out his name.
The owner is a farmer in our village, but quite outside the village centre where we live. She said she knew the dog had wandered off but he often does and then comes back she says.

She thanked us for helping but wasn't too happy to hear she would be getting a bill from the Tierrettungsdienst for 45 chf. She didn't have to pay on the spot (she said she forgot her wallet)

but they will send her an invoice.
I think she should consider herself lucky as had we involved the Tierschutz, the fine is much heavier.
I understand that many farmers do not fence their properties to keep their dogs from running off but it seems to me the biggest danger to a dog running off is cars. Although the dog was castrated, the owner said he must have run off as he smelled a female dog in heat.
It wouldn't surprise me if the dog shows up again. We seem to have a knack for attracting dogs that run off. During this entire episode our 3 dogs were barking at the window very excited at the prospect of having a new friend.
We have a good reputation in the village. Not too long ago we waited in the pouring rain for someone to come and deal with a cow that strayed out of the electric fence enclosure. The cow was very near the main road. Cars just kept driving by. We stopped. Since then, every farmer that I see gives me a big wave. Surely others saw this dog walking alone this morning but never stopped. Everyone today is busy, but you should never be too busy to take the time to care about someone or something else.
