4- How much does he weigh?

Hi Dr Peter,

Basil is a six month old border terrier. I think he weighs around 5 kilos. We walk him regularly in different parks, as far as I am aware he hasn't eaten anything dodgy but I don't really know. Again, as far as I know he doesn't have any pre existing medical conditions. Today and Tuesday when he was first sick he is more sleepy than usual. When he is well he is a very lively puppy.

Thank you

1- Does he have diarrhea?
2- Can you take a look at his gums and see if they are pink or pale?
3- How many hours since the last time he vomited?
Customer: replied 3 years ago.

He has had diarrhea, the first day he was sick. He did a normalish looking stool this morning after he was sick. He vomited today at around 9.30 so 3 hours ago. His gums are pink but they are quite pale.


Friend, vomiting can be caused by many different conditions. It will be difficult for me to determine the exact underlying cause without a hands on examination and some testing. But, common causes are: A simple gastritis, dietary indiscretion, intestinal parasites, ingestion of a foreign body, infections, etc. to name a few causes.
If you are seeing pale gums it is a concern. Pale gums could be a sign of severe dehydration, anemia, poor circulation, etc. Having pale gums could have a fatal outcome if underlying cause is not treated and corrected, for this reason strongly recommend having him checked today by a veterinarian. He will need supportive care of IV fluids while vet does some testing to determine the exact underlying cause. In the meantime, in any case of vomiting the first thing to do is give the stomach time to rest. This is what you can do:

1- Do not give things like Pepto Bismol or imodium. Start him on Zantac (ranitidine) 75mg 1/8th of a tablet every 12 hours. You can buy Zantac over the counter in any pharmacy (chemist).

2- No food or water for 2-3 hours. Need to give his gastrointestinal tract time to rest so that when you do offer water he is able to keep it down and does not vomit.

3- After 2-3 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.

4- Follow up with your family veterinarian for a hands on examination.
