I agree with everyone else, congratulations. Great Pyr. are wonderful dogs and your two are beautiful!
I also am going to second the suggestions about giant breed nutrition and basic training. It is one thing to have a puppy do that, it's cute and makes you feel safe but when you have two very large unruly adults it is a different story. Very basic stuff like sit, stay, come and being able to recall them go a long way to making a well adjusted adult. You could do a simple google search and get the basics of large dog nutrition, it really is different from other breeds.
