That was the writers way of saying imprinting is real and I agree. They totally take after their owners and what you said implies to me that dogs are best suited with one person , or at the very least their personalities are more consistent.

You don't have to tell me twice about the food ritual for them haha I've been around dogs where they are absolutey harmless , kids could be as rough with them as ever to the point where you'd think they'd get annoyed and their unphased but come near their bowl when their eating and you're liable to get your head snipped off.
