Need advice Moscow

I’m coming Moscow on a student visa I’ve a dog I love her a lot if I bring her to Moscow ? It is challenging in terms on immigration and in my country we have a park outside for dogs to poop we just have to pick it once she is done so she got a habit of pooping and peeing outside of the house on correct spot she is disciplined Labrador is there any challenges of bringing it there ? If there is such spot too ? It is nearby from every avg appartment there how it works ? Any guide will be appreciated thx
