Vetionx provides this online service so that is format that I use, not the phone. I am impressed by your dedication to your buddy. I hope we can improve things for you. The homeopathics can be used along with prescription medications. You would just need to give them at separate times so the body has time to respond to the homeopathic before needing to focus on the drug. I hope that you will be able to reduce the amount of Rimadyl needed. You might want to Google it for side effects in labs I like to start with PROMAXOL because it contains all the ingredients of ARTHRO-IONX plus the LM potencies of each ingredient. Initially I would split the dose and give a 1/2 dose on the breakfast food and a half dose on the supper food. Once you see improvement you can switch to ARTHRO-IONX. I would also give PROBIOTICS and OMEGA 3,6,9 to support the body. What do you feed him and what kind of water does he get? These factors influence the body.
I would also get a veterinary chiropractic exam. Proper alignment can help reduce stress on the hips and knees.
