Thank you to all who responded to my plea. My 12 year old black lab (named Cashew) was found on Saturday (after missing 3 days). A lovely lady saw him wandering the streets and thought it was her neighbour's dog. So she approached him and then realized this was an elderly dog (her neighbour's dog is only 2 years old). He didn't have his collar on anymore. She put a leash around his neck and let him lead her. He led her to an apartment building. She rang the doorbell and a lady answered. She said: "Oh yeah, I took him in for 3 days, but I let him back out today". She couldn't believe her ears (and neither can I!)... She went to the SPCA (but wouldn't bring Cashew in because she was afraid they would keep him and then euthanize him) and asked for the owner's name and phone number. She then called and returned him to our house! This lady is an angel sent from heaven (she has 3 dogs of her own, so she knows...). Cashew just walked in, as if nothing had happened, had a few doggie cookies and went to sleep. Needless to say we were all shocked. I just wish people would realize that when they find a pet, they shouldn't keep it! They need to contact the local SPCA, put up posters, ask around. He was only 1-1/2 blocks away from home!!! He was actually on his way back home when the second lady found him. Needless to say that now the fence has been secured (there was about a 4 inch gap on the side of the fence and he managed to squeeze himself through there...). I'm glad we had a HAPPY ending.
