Way to go! You are amazing caregivers to your canine family member, Rebel.
I also had a special dog who had a very sensitive digestive system and would vomit and experience diarrhea if his protein sources weren't exact. In his latter years he had trouble with his hips and with arthritis and we fed him FECO (Full extract cannabis oil). This would give him a pain-free good quality sleep and the next day, he would be able to get up and down and negotiate the few stairs we had in our house without loosing his back-end on the way up or down. His transformation was remarkable and he lived until he was almost 17. Cannabis is a super-food and a medicine. With the correct dose and application it is just as valuable to animals as it is to humans. They too, have an endocannabinoid system and it can be just as deficient as ours.
