Dildogging

Dildogging is a sex act in which the dog remains passive and the woman uses his penis in a similar fashion to a dildo.

This activity is not often performed by real zoos and is more common in pornography than in real life. However some people have reported dildogging with neutered males who are willing sexual partners but no longer have the hydraulics for full erections or the instinct to mount and hump.

Dildogging is considered by some zoos to be a moral grey area, possibly permissible if the dog seems relaxed or to actively enjoy the activity, and dubious if they seem tense or otherwise disinterested. Other individuals see it as completely immoral due to the dog’s lack of active participation in the activity and therefore questionable consent.

Zoo Opinion

Most zoos would agree that this is something that they would not do and is extremely controversial, with some going so far as to constitute this act as a form of Animal Abuse or Zoosadism.
