Rottweiler is Mom to Two Lambs.

Lucky and Charm are two lambs that are being reared by Molly the rottweiler:

Ms Foster added: "The cat came into the kitchen the other day and walked over to the bucket where the lambs were sleeping, but Molly pushed her away as if to say: 'They are mine.'
"She will let the sheepdog have a look, but only for so long before she pushes him away as well."
