1 / 4   A heartwarming bond has developed between a rescued calf and an Australian shepherd at a sanctuary farm in Ontario, Canada. Lincoln, a nine-year-old Australian shepherd, takes his brotherly duties very seriously, and seems to feel overprotective of Calvin, his six-month-old little brother, even though he is a calf. /VCG Photo

They’re very gentle with each other, it’s so sweet,” Mostacci said. /VCG Photo
