I have obtained a pet while in Russia, how do I take it home?
Cats and dogs are inspected by US customs upon arrival. Any animal that is deemed not to "appear healthy" may be quarantined for 30 days. In addition, dogs must have proof of receiving a rabies vaccination within 30 days, but no sooner than three days, prior to import. More information may be found in a brochure available from the US customs website.

How may I travel to Russia with a pet? 
Russia requires imported pets to have an international pet passport. Such passports can be obtained at veterinary clinics and basically say that your pet has a clean bill of health. Upon entering Russia, you will need to register your pet with customs officials and pay a small registration fee. You should be aware that Russian dormitories do not allow pets in any form, so it is likely that you will have to find other living arrangements with your pet.

May I keep a pet in the dorms?
No.  All university dormitories prohibit pets.  If you wish to keep a pet in Russia, you will have to find a private apartment that allows them.
