Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today. I do apologize that your question was not answered before. Different experts come online at various times; I just came online, read about your wee one’s situation, and wanted to help.

Now with Ollie being so young, we do need to tread with care and be proactive to get him settled. This is because young dogs are at high risk for dehydration, weakness, and weight loss when they have both vomiting and diarrhea. So, to start, if he cannot keep water down, has belly pain, pale gums or could have eaten something harmful; then we'd want him seen by his vet urgently.

Otherwise, if we can put those red flag signs aside, we'd be more suspicious that his upper and lower GI upset is due to a bacterial or viral gastroenteritis, pancreatitis, parasites/protozoa infections, or general dietary indiscretions. And with those in mind and if he can keep water down, then we can try some supportive care at this stage. To start, if he hasn’t just vomited (since otherwise we’d need to rest his stomach for a few hours first), then you can consider treating him with an antacid. Common OTC pet safe options would be:

Pepcid (More Info/Dose @, Zantac (More Info/Dose @, or Tagamet (More Info/Dose Here @ Whichever you choose, we’d give this 20 minutes before offering food to allow absorption. Of course, do double check with your vet if he has a known health issues or is on any medications you haven't mentioned. Though if you try this and he cannot keep it down that is usually a red flag that we need to bypass his mouth with injectable anti-vomiting medication from his vet.

Once that has had time to absorb and he is steadier on his stomach, you can consider starting him on a light/easily digestible diet. Examples you can use are cooked white rice with boiled chicken, boiled white fish, cottage cheese, or scrambled eggs (made with water and not milk). The aim of these diets is that they will be better tolerated/absorbed by the compromised gut. Therefore, it should get more nutrients in and result in less GI upset. Whichever you choose you can also add fiber (ie canned pumpkin, all bran, etc) to the meals to bulk up his stools and reduce the diarrhea quicker for him.

Since dehydration is a risk for a young dog like Ollie, we need to keep an eye on his hydration. To check this and ensure he’s not becoming dehydrated, there are a few things you can test. Further to checking for gum moisture, you will want to make sure his eyes are not looking sunken and that he doesn’t have a "skin tent" when you lift the skin. To see how to check these parameters for dehydration, you can find a good video HERE ( If you are seeing any signs of dehydration already, then that would be our cue to have him seen before this becomes an additional issue for him (especially as it is often dehydration that makes them feel unwell).

Finally, as long as there is no blood in those stools, you can consider trying a pet safe anti-diarrheal. As I am sure you appreciate, these would not be a cure for infectious issues; but it can still be of benefit. It will reduce diarrhea load, allow the body to absorb more water/nutrients, and soothe the upset gut. In regards ***** ***** options, the one we most commonly use is Kaolin/Kaopectate (More Info/Dose @ This is available OTC at most pharmacies. Otherwise, Propectalin, Canikur, Fast Balance, and Protexin Pro-Fiber (which is available OTC at vets, pet stores, and even Amazon) would be another option. All will slow diarrhea and those last ones have the added bonus of providing support to the delicate good GI bacteria. So, these can be used as a short-term means of soothing his upset GI..

Overall, a wide range of agents could trigger the upper and lower GI upset we are seeing with Ollie. Therefore, in his case, we’d want to start supportive care to settle his stomach. If he cannot keep that or water down, appears dehydrated already, or doesn’t respond to the above within 12-24 hours; then we'd want to get his vet involved. They can assess his hydration, rule out fever, make sure there is nothing in his stomach that shouldn't be there or any sinister viruses present. Depending on their findings, his vet can treat him with injectable anti-vomiting medication +/- antibiotics to settle his stomach, and get him back feeling like himself.

Please take care,

Dr. B.
