I too am very happy that Mac got through that ordeal. And I can only imagine how horrific it must have been for you and your family.
It is so very true that you really need to be careful about the disposal of food. We have a neighbors dog that had (and still does) come 'a' hunting for rubbish. He has gotten sick from the rubbish hunting, but certainly not to Mac's extent. We smarted up and now lock the rubbish in the shed overnight. Now that we (extended family) can have maybe 3-4 dogs up there at a time, we are more aware of it.
But for folks that don't have a pet, just be mindful that maybe a neighbors pet will come wandering over.
RG, love the kayak picture, but like SIKSURK said, how do those little paws hold the paddle? He must be very clever
