Cartomancy Common Keywords?

Cerulean

In the following three different decks, published by Lo Scarabeo: a common image: a dog, although different breeds of dogs depending on the deck. Note the shades of meaning that seem almost a common 'theme'--perhaps a fluke?

Dream Cards (Modern Italian) - (16) Good companionship. Harmony within the family

Cartomanzia Francese - (French- LeNormand) (18) - Friends you can trust surround you. Stop crying and live on! Meaning: Long-lasting friendships, loyalty, support

Sibilla Della Zingera - (Early 20th century (?) Italian)- (88/37) - Fedlta - Fidelity

I've noticed certain themes such as a house or a dog is usually beneficial, kindly in terms of meaning and symbolism. But the image of the cat doesn't fare so well in the Sibilla...have to look at other cartomancy images.

It may be a publishing or similar cartomancy tradition, but I thought I'd mention this. Perhaps a general cartomancy dictionary already comments on this? Have others noticed small similarities in certain oracle themes?
