    public long SpeciesID { get; set; }
    public long BreedID { get; set; }
    public Calendar DOB { get; set; }

}

public class Calendar
    {
        public int Day { get; set; }
        public int Month { get; set; }

        public DateTime DateObj
        {
            get
            {
                if (Day != 0 && Month != 0 && Year != 0)
                {
                    return new DateTime(Year,Month,Day);
                }

                return DateTime.Now;
            }

            set
            {
                if (value != null)
                {
                    Day = value.Day;
                    Month = value.Month;
                    Year = value.Year;
