In my own language - Portuguese - dog owners are just said to be the “dog-owner” (we have a feminine and a masculine version of the word “owner” so it fits nicelly) so the English-language use of “mother” and “father” tends to instinctivelly make me think in a very similar sense as your daughter seems to be using.
They’re all siblings, including their parents and the family’s dog.
My daughter says our dogs are her brother and sister. But she is not an embryo in a test tube, so it’s slightly different.
My dogs are my family, so I get her.
It doesn’t help that I pick up the little dog and carry him around telling him that he’s my little baby boy.
Ed…ward
NOOOOOOOOOO
