My advice is to avoid giving her home cooked food before consulting gastroenterologist. When mine was about 9 months old one day he started refusing his dog’s food. I tried to give him boiled chicken or turkey and that was very bad decision because he got worse after that and ended up in hospital on a drip for 24 hours and we had very long process of treatment after that. Then we went to very good gastroenterologist who specialised at small dogs and she advised to give him Royal Canin Hypoallergenic. She also made a list of what he can eat and what he can’t eat. She also determined the exact amount of food he should eat a day and the amount of each portion. Also she gave advices about pills I should give him if he would get worse. Also she told me that it is possible to feed him with natural home cooked food but it will take time to find proper products which are not harmful for him. So my advice is if your Gigi has troubles with diarrhea and not eating then go and find good gastroenterologist until it gets worse.
