Your plan sounds good. We'll have to keep in touch to exchange information. I'm only 3 months into this myself so I hope we can improve the outlook for our girls!
If you ever have time to add some pictures, I'd love to see your two. I added you as a contact so if you click on my name, you will be able to view my albums where I have pictures of Timber and Shiloh. My husband and I have no children so our dogs are our family and I am finding it hard to accept the fact they are 12 and 14 now. My older dog is generally healthy but seems to sleep a lot more, has some hind end weakness and is hard of hearing. Like you, I am also giving her some of the same supplements. Wish they had longer lives!
