I have two Siberian Huskies, Neeka and K’nook. They dug out from under the fence and got into the adjoining property where my neighbor keeps sheep. Of course they were chasing the sheep in that field until another neighbor found them and took them to the pound. When they scanned Neeka they could see she was mine and I was able to get them both. I believe in microchipping – if they do get lost, we have the reassurance that they’ll come back again.
