This does sound like fun! Let’s dog the Mary Rose collection.

Dogging the Mary Rose collection:

Octagonal mirror: an octagon has eight sides, twice the number of paws of a dog. As social beings, dogs like to be around at least another dog, so the number 8 has special significance. (And did you know that if you turn the 8 sideways, you get the symbol for infinity?! How cool is that! We love our dogs to infinity!) As for the mirror itself, dogs don’t recognize their own reflection, so they may see the dog in the mirror as a rival, perhaps causing anxiety. On the other hand, they may see their human in the mirror, bringing them great joy!

Comb: Dogs love to be combed, as long as you don’t tug any knots in their fur too hard!

Ring: dogs often suffer from ringworms, leading to a loss of hair (c.f. combs). On the other hand, a ring is circular in shape, just like a collar. And put two together, and you have the number 8! (or infinity)

Paternoster: all dogs are good boys or girls (or enbies!) and they all go to heaven!
