They say dog is man's best friend, but not many owners can say the bond began before they were born. Toddler Carter and his pet Toby have developed a special relationship at their home in Indianapolis, Indiana, and become virtually inseparable. Parents Devin and Jake Crouch have been documenting their progress on Instagram and now have more than 5,000 followers. Their chemistry began when Toby would curl up to Devin while she was pregnant to keep her safe, knowing 'something was going to change his world.'
