I have a dog but I am not a dog person. I am a sucker, however. In the last 3ish years, I've found 4 different dogs wandering (one of them twice) when I've been walking my own dog. Two had collar tags with phone numbers - one owner was annoyed to be inconvenienced working from home that he'd have to come to meet me to get his large, very excitable dog back (the same dog I found a second time about 4 months ago. This time as I was about to start dialling the number, I saw him approaching and recognised him so I walked away. The collar seemed to have some sort of tracker on it, so obviously a repeat offender.) The other was bemused that I didn't know she was jogging out of sight in another part of the park while her dog was following me in the opposite direction. One untagged one was on a very wet day in an empty park, so after doing a full loop and meeting no one, I put the dog in my car to bring to a local vet to be scanned for a microchip. The vet said the owner was an elderly lady who was fretting as he had escaped and she was grateful and sending someone to collect the dog (luckily the dog was registered there so they were happy to take him).
This morning I walked around with the dog for about half an hour, asking people at bus stops if they'd noticed him, trying to work out which direction he'd started from. No sign of anyone looking for him, so off to the only vet open on Sunday, at the local university. They rang the owner and gave me her number. She off handedly said she was out but would get her sister to meet me at her house. No thank you, no sorry for the inconvenience. The sister said thanks for dropping him and closed the door.
I'm tired and grumpy anyway this morning, and I missed something I was planning to do, to find this dog's owner, and the general ingratitude of dog owners near me has really annoyed me. DH claims to be more of a dog person than I am but would only have intervened in the one this morning as it was beside a road, he's have left the park dogs to their own devices. Maybe I will in the future.
