Hi. Im looking to transition my 7 year old GSD and starting new pup coming 5/25 on raw. I have been reading TONS. Im mainly worried about the pup and raw as the whole calcium to phosphorus ratio has me VERY worried. Currently i use a quality kibble with my 7y.o. and supplement with Pet Ultimates probiotics , Solid gold sea meal, PRN prozyme, Nupro + glucosimime formula (silver bottle). From reading the various Raw feeding i feel the whole prey makes more sense but since we aren't feeding fresh kills i think supplements are important. I have seen that people still supplement when feeding raw. Are the ones im using good ? Should i explore others? Is there one that could take the place of the all ones im using like an "all in one" ? Im also worried that the Nupro or Sea meal could throw off calcium/phosphorus levels but i haven't researched levels yet . I have seen Sunday Sundae mentioned here, SH-emp oil and Feed-sentials. any experience with them? So whole prey raw feeders what supplements do you use. From my understanding it seems many don't really supplement as the feeling is nutrients should come from the diet. Can i be doing more harm then good with to much of certain vitamins? Specifically, I hope to hear for ones that will be good for my future puppy as i don't want to mess up calcium/phosphorus levels.
