Candi darling, this all makes me cry too. We can all look at this from different points of view, but in many, many religions, in many beliefs animals that are human's closest companions are all God's creatures. Even though it is not allowed to pray for them directly in church, or light candles for them, I know that even any Orthodox priest would tell you-you CAN say a prayer for them at home, you CAN have such a close connection to them, as they all are loved as god's creations, all of them are remembered. Especially if you look at how close this connection is in Native -American culture where animals are not only respected as equals, but revered as teachers and protectors as well-so i think the poem you mentioned can be applied to an animal that you consider noble. Yes, Sunday is Voskresenie in Russian () which means Resurrection, literally. Lazar is an old Russian name, I know literally one person by this name, and yes, it is the same as Lazarus, old names had pretty deep meanings because we used to give names by the name of a saint on whose day one was born, but most people don't anymore. I've noticed long ago how unique his name is, especially for a dog, but how he conquered death as little puppy-that's a story:-). Isn't it amazing? I AM SURE he is in doggy heaven now.
Now, i usually go to the cathedral of Holy Virgin "Joy for All Who Sorrow". Hope you will have joy, darling, you have another wonderful doggy to care for, and probably your family or friends too, and I hope you will feel better soon knowing Lazar is a happy doggy now.
