Oh, that's great, thank you!! I know different breeds have different prints, and I wasn't sure what I was seeing, or even if it was a dog or maybe a coyote, this will be very useful, thank you so much! We have had pretty good weather here, although we did just have a big wind/rain storm, so lots of mud right now, and I don't think it will be too long before we have snow. Prints and droppings are 2 things I have been searching for. I've heard of shelties missing for a very long time too, in fact on facebook I've connected with two women who's shelties went missing at the same time, one in my town, the other in Yarmouth, south end of Nova Scotia. The one in my town was gone for 5 1/2 months, the one in Yarmouth was gone for 7 months! Both were found safe and sound. And I read on here about Aspen, that one just blew me away! 20 months!! It is a relief to know that they are very hardy and such good survivors, but I sure hope I don't have to wait that long! We love our boy so much, and really miss him, we are SO ready for him to come home!
