Great news! All four dogs were found safe and sound (a little freaked out, but it's to be expected), tied to trees in a parc. The people who found them called the SPCA who took photos and sent them to the owners who confirmed that yes, those were their puppies! The car is still at large, but they more or less care now that their beloved doggies are home!
Here's the message I got: "DOGS WERE FOUND !!!! THANK YOU to everyone for all your good wishes, help & positive thoughts!!! So someone called the SPCA when they saw the dogs tied in a park somewhere in Montreal. The SPCA went to get them and had their pictures in hand, and knows all their names, and they have been fed and watered and tucked in for the night!"
There is much rejoicing!
Very happy woos,
