The rosary is required by the Constitutions of the Order of Preachers to be prayed daily. I don’t know why they would not mention it but it is prayed daily in the Novitiate and throughout the Dominican life. Check out the Western Dominican Province.
St. Louis de Montfort got mentioned. Little known fact. He was a “third order Dominican”, something like today’s Priestly Fraternity of St. Dominic.
