Hello Ninnu! I never heard about this dog breed (Russian Tsvetnaya Bolonka) before, by the way, but I am sure she will settle in soon and she won't be shy as she receive a lot of love from you and from your family.
By the way, her name (Antonina) means "Beyond praise" in Russian and in Spanish. "Highly praiseworthy" in English, "Priceless" in Polish and "Praiseworthy" in Latin.
