What should I do for my fox terrier who lately throws up a little in the morning?

My 4 yr old Fox Terrier is up to date on all her meds. We moved from CA to FL about 2 months ago and the last 2 weeks she has been not eating as much. This weeks she wakes up, throws up a little, then doesn't want to eat or drink and is shaking like shes freezing. Some days she has diarrhea and others she has bright orange in her poops (which I thought was carrots since we usually chop some up for her dinner but stopped last week). When she lays next to me and I can hear her stomach rumbling. But by mid afternoon she is back to normal, running around hyper, hungry and playful.

Vet

Take one of those orange stools with you and get her to the vet - pronto. Orange stool can indicate liver disease, as can the throwing up. Sometimes hyper dogs can overcome being sick and look fine for part of the day - but something is definitely developing, and you need to find out now so it can be treated or managed.

You should take her to the vet to run some tests because vomit and diarrhea are very general symptoms that appear with tons of diseases/problems...First of all she might need an x ray to explore the case of a stuck foreign body which gives those two symptoms..Second she needs a blood test to see her general condition and her hematological profile at the moment. If the number of the white blood cells or lemphocells are impaired it could be a gastroenteritisNow if the orange color isn't from the carrots then u should not delay the visit to the vet cause orange stool is usually a sign of excess bilirubin which is a yellow bile salt. Could mean liver, pancreas or bile problems all of which are conditions that should be monitored and managed from your vetI wish All the best..!

call the vet...the weather in FL is way different than CA and it may be bothering her
