Fetch turned into a chase

Yesterday morning i was playing fetch with the dogs. This is outside the dog pen and there is no fence. All of a sudden a stray dog came walking through the field and Mojo and Mijne went after the dog right away. They started to chase it, went over the Shiney Rock rd where i lost sight of them. I  called and called, nothing. My brother and sister-in-law who are here to visit, got in the truck and together we went down  the road. In the meanwhile Martijn was at the look out at the house. And then i saw one of the dogs crossing the road again, we went there. Neighbors who were alarmed by my calling, told me that the saw the two of them but that was it. While we were talking i saw Mijne wondering through one of the neighbors yards and when i called him he came right away. Also Mojo who was at the same side of the road showed up after another 5 min and while i was talking  to another neighbor. Lost my voice for the day, but he, was i glad to have those two back in one piece.
