I am sorry to hear that. I have only ever given my dog raw chicken liver and heart but that was about month 2 into our transition. I am new to raw food but I can say that it took about three months for Bella to transition to completely raw food. I know of some dogs who can do it in less time but she took a while and we are still slowly adding more and more to her diet. Each time I add something new she does usually respond at first with diarrhea and sometimes even vomiting. One thing to note is that heart and liver meat is super rich and should be added slowly into their diet and only in small amounts. I have been told it should only equate to about 10% of their diet.
I hope your puppy feels better- all the best!
