As far as I know, there are no particular laws against bestiality in Russia, but porn distribution here is illegal itself.
In general terms this is true, but this applies only to commercial distribution. With non-commercial distribution, the situation is that the issue is as debatable as it is irrelevant for practice.
The thing is that Russia is often imperfect legislation is often compensated by the complete reluctance of the law enforcement system to monitor the implementation of this legislation.
True, there is a nuance. All of the above occurs if the incident does not cause a wide public resonance. Otherwise, the punishment will be as divorced as possible from the evidence process.
In Russia, there really is no legislation prohibiting bestiality, but this is only a consequence of the insufficiently timely development of the legal system in this country.
In Russia there is a law on cruelty to animals, for example, and the corresponding attitude of society to the topic of zoo. And if the incident had a wide public outcry, nothing will prevent the Russian court from convicting you of any article that it considers necessary. The best and most expensive lawyers in 95% of cases turn out to be powerless.
Before that, you also have to face the Russian law enforcement system. Not that this is such a hell, as is often stated, rather, it is simply very outdated and weakly interested in its own effectiveness.
Sometimes it causes trouble locally.
Therefore, if you are seriously going to conduct zoo pornography officially in Russia, I am sorry for you ... =)
The only option to do this here is illegal production, in the hope that you will not be interesting to anyone. But that's all until a certain time.
And yes, there is no law prohibiting zoo in Russia exactly until there is no attention to the topic of zoo. The Russian community is currently trying to once again draw no attention to itself. How much is correct, the question is very discussion, but at the moment it is.
And yes, in general, I am not too positive about porn production, much less commercial. But above I tried not to take this into account.
