People are giving you advice to help your dog, what they are saying WILL help your dog, unless there is something physically wrong with her, that only a vet can help. The fasting and bland food is something you HAVE TO DO if you want this to stop and want to try to find out what the problem is. Stop asking for advice and making excuses if you won't do what they are telling you to do. Fast your dog for 24 hours, no biscuit, no chew ezz. The next start her in 2 to 34 very small feedings spaced thrughout hte day of either boiled chicken and rice or hamburger and rice. You can make a batch and use it for sevral days. Do the same the next day, an the next. Then try a small feeding or her normal food. Throughout this time do not give her biscuits or cheweez, whatever that is. If you want her to get better, and don't want your mom to get rid of her, DO IT. I am not berating you but you are talking about yoru dog bieng sick every day, your mom wanting to get rid of her, and you keep making excuses as to why you won't try these things peopel are telling you. If she throws up the Nutro, then no, she can't eat it for the next 3 months, you could jeopardize her health. You really really need to do this, you asked for help and there it is. I really don't want to see something happen to her or her to be rehomed because you wouldn't try, please try it. I hope she gets better.
