Today was the big day. Ken got our dead fish and placed it in the pond. We then took Sky out and followed Peggy's suggestion as best we could. You can see on the video exactly what we did. We will know in a couple of days if it has solved the issue. Will let you know then. Today is Friday, and guess what, the excerise worked! Sky just gives the pond a quick "sniff" and goes on with his wanderings. Thanks, Peggy!
