@Sergei--and--Larina0 No, unfortunately Airbnb has no option to finely tune your "Pets Allowed" rule to restrict by size, species, or number of pets. You may specify a flat pet fee, but it apparently only allows one fee per stay, rather than per night or per pet. And if a guest wants to bring a large dog or a Siberian Tiger for free, all they have to do is say it's an "emotional support animal" and Airbnb will require you to let it stay.
Good luck!
