No problem, Cheryl, I’ve learned a lot on this site. One thing to remember is that you don’t have to pick a food and stick with it forever. Many believe, including myself, that it is best to offer a variety of foods. Here is a link with some information on a rotation diet: /frequently-asked-questions/diet-rotation-for-dogs/
I feed a couple different brands of both kibble and canned foods to my dogs and cats. Also, as I mentioned above, I also add some fresh foods as well.
One of my cats also had struvite crystals and ended up with a urinary blockage which landed him in the emergency clinic. So, I really now know the importance of adding moisture to their diets!
These changes don’t have to happen all at once. Take your time and try out new things to see what works!
