Can any one give me some piece of mind?

I put a message on here a month ago as my 9 month old pup had started to lose appetite, be clingy and a little sick. This all seemed to go after a couple of days of tlc. I though it something to do with her begin in season for the first time and hormone levels.

However within the last week she has begun doing this again now even worse, she is sick between 0-4 times aday, has a bad upset stomach, and on occasion is very clingy and cries, she is also up and down all night. We had her to the vets rite away and has since been back 3 times she has had injections, tablets and other medication but they have made no difference. She finally today had a blood test and now we have the wait for the results - The vet said he had no idea what was going on and suddenly had a pretty serious tone- I am obviously very worried...

Does anyone have any ideas what this can be? I have had family dogs before but none have ever got sick! We rescued her and I absolutely adore her... Im just looking for a little piece of mind while I wait for the test results...

I am so glad the vet is doing blood work, I am surprised it took more than 3 visits! I wish I could give you piece of mind but you are doing all you can.
Hopefully the blood work will give you some answers and your pooch some relief. I am assuming your vet has taken a stool sample and your pup is up to date on all the shots. Please let us know what you find out and how your dog is doing. Best wishes to you.
