Owner found - was local farm dog!
Pity the police didn't (apparently) direct the finders to the dog warden and that it wasn't microchipped. It's ging to cost the farmer a bit to get him back from Scotland
Someone picked up my dog years ago in the scottish highlands. They called into the local petrol station asking for the police station, there isn't one, as his tag had an Exeter address. The garage owner recognised the dog and told them to take it back where they found it and let it go. Luckily they did. He ambled home ( the house can't be seen from where they were picnicking) and I was none the wiser til we called in for petrol next day in my little van and Stan said 'He was riding in a big volvo yesterday'
If whoever picked him up is reading this - thank you for caring for him - no mobile phones/microchips then.
