Why is this dog smiling???

That's easy! Jewels is smiling because she and her puppies are safe and warm and well-fed and loved.

UPDATE FROM ALL DOG RESCUE NEWSLETTER:
Puppies!
Several weeks ago, All Dog Rescue got a plea for help from shelter partner Red Lake Rosie's Rescue. A very pregnant stray had found her way to RLRR, and they were hoping to get her into foster care before the puppies were born. All Dog Rescue fosters Shelley and Craig immediately said they would provide sweet Jewels with a safe, loving foster home. Everyone was on pins and needles in the few days it took to arrange transport, but everything worked out - Jewels waited to give birth until she was safe and sound in her foster home.

Here is proud momma Jewels with her puppies, now around 3 weeks old. Once they are old enough, the puppies and Jewels will all be spayed/neutered and available for adoption. In the meantime, you can find lots more pictures and some video of Jewels and her puppies at All Dog Rescue on Facebook.
