Salt weasels and others

Delicous friends, could somebody tell me whether it is possible to have a Salt Weasel as well as a Haunted-Looking dog and a Rubbery Euphonium, or are they mutually exclusive ?

They’re mutually exclusive - the card to receive one can’t be drawn while you have any of the others.

Ahah! I can stop trying to get the dog when I already have the euphonium, then… Thanks a million, kind Sir.
