Hi C W, have you tried wet tin foods, low fat ones, wet tin is better for dogs then kibble when having stomach problems, I’d say she getting stomach acid after eating a high fat% kibble… what was the fat% & protein% on the Royal Canin gastro, find another brand kibble close to the R/C in fat% & protein% & get a few different flavours then give one flavour for breakfast the other flavour for dinner, rotate so she doesnt get sick of them, I still give the vet prescription diet but I mix with Wellness Simple Duck & Oatmeal, the Wellness Simple kibbles are average size, also tuna is low in fat, I give tuna in spring water drained then mix with pumkin & a boiled egg, for breakfast, kibble for lunch & kibble dinner..When a dog stops eating something, normally something is wrong…
