Over the 40 years have had mongrel mixed, spitze-mixed and pedigree german shepherds, rottweilers. My lastest rott die 6 months ago, buried in my garden. I am now looking for mixed breeds of short body (15inch wither ht and below). My new dogs will be kept out door, free to roam within our 4,000 sq ft compound. They will be housed in 4ftx4ft and 2ftx4ft kennels, located within a dog alley of 80 sq ft, which is latched when there are visitors.
