Saw Two Dogs

Was walking my dog about an hour ago and saw two dogs; possibly lost. There was a white one and a smaller black one. I think the small black one was a terrier. The larger one was about 50 lbs and had curly fur; maybe a water dog of some kind. They were off leash and the larger one had muddy legs like they had been treking through the marshes between Demott Dr and Fieldthorne Terrace in Southern Walk. I spotted them at the end of Fieldthorne Ter near the park. I then walked my dog home and looked around the neighborhood for them for about 30 minutes but they were gone.
