I am so sorry to hear that your dog is sick. Given that Murphy had such an aggressive cancer and such little time, I decided not to hold back on anything that his Doc wanted to try. I set the ground rules pretty early and told her I did not want to hold back. As far as I was concerned, Murphy's biome (gut) was really healthy. I transitioned him from kibbles to raw in just a one day. It might have been kibbles for dinner and raw for breakfast. I just don't remember. What I do remember is his first raw meal. He lightly smelled the bowl and then dove right in.
I hope my post did not sound like I have Murphy on a Keto diet. It's keto of sorts in that there are no carbs and no sugars in his diet. IT is high fat and the only fat is what is in the raw food I get for him. I won't give him any typical doggie treats or veggies like carrots or green beans.
I'm getting his food from a local distributor. I've been feeding him beef with organ meat and beef with tripe, no chicken and no turkey. I'm getting his food here:
Maybe there is someone close to you that offers something similar.
Honestly, all of the supplements and and food that I have Murphy on are just part of the equation. They are meant to boost/support the immune system while the Sanawave does the heavy lifting.
