This is my first time to post or try to get advice online. I have read some posts and it seems so helpful and kind. My lab started throwing up blood on Thursday. My husband and I took her to the ER Vet at 1130 pm. They said xrays shows she did not have any masses but did have hardness in her back mammory glands we should have looked at. She does appear to have an ulcer possibly and they have medication. She is still heaving at times and throwing up blood less but still. She gets up for a moment to go outside to the bathroom then just lays. Does anyone have experience with this or any advice. I feel so bad for her and just don't know what to do. I am giving her pediasure water cubes and she will eat rice and chicken I made. She does end up throwing up a couple of times. Advice is appreciated.
