1- We all probably have heard that dogs and their owners are alike. Even if we didn’t, lets remind you all: "One Hundred and One Dalmatians 1961" Walt Disney’s production: in its introduction sequence, which shows several owners and their dogs and their similarities.
2- The other thing is: after the years of marriage husbands and wives look like each other. (At least I have heard this from 5 different people with different backgrounds in last 6 months)
So don’t you think the out come is a little bit strange: from 1 and 2 one can assume that dogs and spouses(Husband or Wife) are the same:
1&2 => Dog = spouses.
The only thing that bothers me is how can we realize, which one is the owner which one is the dog.
