Hi. I think it is very confusing because there is so much info, and every dog's situation is different. Zeus was very difficult to diagnose as he did not present with the "typical" symptoms. I have had Zeus on many of the recommended products over the years. I, with my vet's support, decided to wean him down to what was necessary for him to lead a high quality life and most importantly, to feel good. He is able to do that on a prescription food and denosyl SD4. That is what works for him. If and when he needs additional "help" we will have some options. That probably isn't the answer for every dog, but as the caregivers we can sort through all the "stuff" and find the right protocol for our pet's particular situation. Zeus will be 7 on the 25th and is doing great, which is way more than I could ever have hoped for when he was diagnosed at 10 mos. I watch him and have annual bloodwork done to keep track of any changes. That is just my experience with Zeus. I don't claim it's right for all, just what works for him. Juliet |
