My 3y old PRT bitch Holly has started to vomit up a couple of mouthfuls of bright yellow bile for the past 2 mornings, i took her to the surgery with me yesterday and was given Ranitidine (150mg) at a doseage of 1/4 tablet twice daily, and was told to give her small quatities of light food. She had two 1/4 tablets over yesterday and another 1/4 this morning, but was still a bit sick. Given the chance she will eat straight afterwards. She had this a couple of times in the past, but feeding her a small amount of kibble last thing at night has always remedied it within 24hrs. Anyone else experienced this with their dog..what worked?
