Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.

What was he on the antibiotic for?

What anti-vomiting medication did you give?

What does his vomit look like?

Can he keep any water down?

Are his gums pink or pale/white? Moist or sticky?

If you press on his belly, does he have any discomfort, tenderness, or tensing?

Customer: replied 1 year ago.
He was on clavamox for 10 days had infection.
After He was done next day he started to vomit on and off, and the next day it got worse and worse towards the evening. He couldn't keep anything down.
I gave him electrolyte water, I made him veggie broth, I gave him probiotic paste, all separate time and tiny bit of each, he didn't keep anything down. Then he went with blood stool, slimy. This was from 7 pm towards 3 am. Then he stopped. So I gave him some kefir. He was able to keep that down. I waited and towards the morning he didn't vomit. But his poo still has blood. I cooked him some chicken, and he ate that with probiot. He's keeping it down. I picked him up some urgent care diet from vet. He ate a bit. I left to work, I didn't sleep all night. He seems to act fine. Gums are pink, not lethargic. Acts normal but before he vomits he cried and before he poops he'd cry.

Thank you,

First, I am quite concerned about your wee one.

We can see vomiting and diarrhea in dogs sensitive to these antibiotics, but to see bloody diarrhea raises worries of other non-related issues being present. This could be an overgrowth of nasty bacteria like Salmonella or Campylobacter. Though we can also see these signs with Parvo and hemorrhagic gastroenteritis. Therefore, while gut upset alone could be related tot he antibiotics, with the blood this sounds to be less likely.

Therefore, we do really need to tread with care. If he is passing more than a spoonful of blood in his stools, then we'd be best to have him seen again and tested for those above concerns. If it is scant blood or until he is seen, we'd want to try to soothe his stomach. If he is keeping food down now but still seems nauseous, then you can try him on an OTC pet safe antacid like 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. Also if you give this and he cannot keep it down due to nausea that is usually a red flag that we need to bypass his mouth with injectable anti-vomiting medication from his vet.

Once he is more settled, you can plan to try small meals of a light/easily digestible diet. What you have offered sounds fine, but I'd note you can also offer cooked white rice with that boiled chicken, boiled white fish, cottage cheese, or scrambled eggs (made with water and not milk). Of course, the OTC vet diets (ie Hill’s I/D or Royal Canin’s sensitivity)can be continued as well. All are easy to digest and all will help reduce diarrhea. Though further to the probiotics (which are good to use here), you can start adding fiber (ie canned pumpkin, all bran, etc) to his meals. These will bulk up his stools and reduce the inflammation and pain passing the diarrhea is causing him.

Overall, I am quite concerned about your wee one. If the stools are very bloody, then this isn't likely related to the antibiotics. Especially if his signs started after the course. Therefore, we do need to be careful with him and would want to add the above into your treatment plan. Of course, if this persists then those other issues would be a worry and we'd need to think about having him reassessed to get this settled as quickly as possible.

Please take care,

Dr. B.

I'm just following up on our conversation about your pet. How is everything going?
Customer: replied 1 year ago.
I have kept him on critical care prescription diet, I haven't seen him vomit.
Although his stomach was making noises, I gave him a dose of Flagyl, that took care of that. And I keep giving him kefir. He doesn't have blood in his poo and it looks ok.He stopped vomiting too.I think that fixed it. But I need to keep watching him.Thanks
