Now that the rule is enforced you might want to change the message one gets when adopting a dog.
Adopt this pet and add it to your collection (currently logged in as: Inkcharm) You could also log out to change to a different account or adopt the pet without adding it to any account.
That could be confusing with the new rule, because it might suggest the idea of having spare accounts that do not belong to other family members to some people.
