Welcome and thanks for asking your question. My name isXXXXX am a licensed veterinarian. I am sorry for the delay in response. If you would like to continue can you please answer a few questions so that I can be well informed and give you the best advice.

1- What is the name of the diarrhea tablets he is on?
2- How much does he weigh?
3- Did he get into anything or eat something out of the ordinary?

There may be a slight delay between your follow ups and my replies as I type out a thorough reply for you.

3) no - he has been under our control the whole time - when taken out on walks he has been on the lead mainly

Anthony, as you may already know he has a low grade fever, normal temperature in a dog is between 99.5-102.5 F. Vomiting and diarrhea can be caused by many different causes. It will be difficult for me to determine the exact underlying cause without a hands on examination. But, common causes are: Infections, ingestion of a foreign body, tumors, etc. to name a few causes.
In this case I would strongly recommend a hands on examination with a veterinarian as soon as you can. Harvey may need some testing (xrays and blood work) to determine the exact underlying cause. In the meantime this is what you can do:

1- Stop the medication for the diarrhea. Instead, start him on Zantac (ranitidine) 75mg every 12 hours. You can buy Zantac over the counter in any pharmacy (chemist).
2- No food or water for 6-8 hours. Need to give his gastrointestinal tract time to rest.
3- After 6-8 hours offer a small amount of water. Wait half hour, if no vomiting, offer small amount of rice (50%) and boiled boneless chicken or ground beef (50%) 4-6 times a day.

My goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back. I am happy to address follow-up questions. Thank you for your business and I hope to work with you again soon!
