With paw tattoos you can play it both ways ! With the haters and non-zooers you can claim it's in memory of your beloved deceased dog. For zoo tolerant or zoo active people... well ......
I think the general and loose rule is you if hide your paw print like below the hemline of your skirt .... it is signaling among zoo people your inclination ! ..it is a 'secret' world , something that you're not too open about, which is why you place it out of immediate view. The photos shown of women previously, of tats above their breasts which are visible all the time, clearly, indicates women who are not zoo.
And if an anti-zoo comes among and tries to shame you, you can always claim ignorance that 'you didn't know'....and 'what an absurd concept women being fucked by dogs !' 'Absolute nonsense !' How wonderful deniability is.....it seeds doubt among even among the most fanatic haters !
