... still no sign of said dog in spite of checking with neighbors, flyers, checking the pound. Any suggestions?
You mentioned the pound, but if you haven't already you might also want to try the local Humane Society or SPCA. Try every animal shelter within a 30-mile radius, especially the small/privately-financed ones. Try calling local vets to see if anyone brought in a "new" dog like yours for an exam.
If you have a photo, call the local papers-- especially if you have a weekly fishwrapper that's delivered in your mailbox. Those typically post the community-service announcements and are responsive to lost-animal submissions.
Try all the local TV stations, especially if you have video or public-access channels. It'd have to be a slow-news day but trying is better than wondering.
Don't quit hoping & advertising. Sometimes dogs are sheltered by well-meaning "foster parents" for weeks or months before they call the pound or see your ad.
One of the local shelters may have more info on coping with pet loss; our local Humane Society has a robust portfolio of pamphlets.
Good luck.
Sorry, no suggestions. I have no sympathy for people who are careless about their animals. I feel more sorry for your dog being left with such "forgetful" people.
Go ahead and slam me if you like but that's my opinion.
Yo, Calgary, you've earned it and I'm happy to.
While you're entitled to your opinion, there could be many more constructive ways to express it. How 'bout "Sorry to read about your pet's troubles, carelessly-caused though they may be, and may I suggest a collar/fence/ID tag/leash/microchips?"
Or did you just wake up this morning with a mouthful of flame to spew?
