Hello! This is normal. You can see a period of no pooping after having diarrhea, and I would not worry that he hasn't had any poop for 12 hours. Just be careful giving him Imodium, it's not safe if given more than two days and it's really safe for smaller dogs. I would keep feeding him the chicken and rice in small portions for the next 3 days, then slowly start adding back in his normal diet. If the diarrhea starts again or he has other symptoms such as vomiting, refusing to eat, blood in his poop, or lethargy, he will have to see a vet immediately. I hope this helps!

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. Do not be too worried about him not producing any stool. Immodium is very potent and works by slowing down the motility (movement) of the GI tract so I am not surprised he has not passed much stool since then. It is not uncommon for them to not poop for up to 3 days. If he is acting well I would not be overly concerned at this stage. Just keep monitoring him and if he doesn't produce any stool within the next 48-72 hours then I would have him checked out by your vet. Hope this helps. Best wishes.

Yes it is safe but rarely effective and used. As a first approach for diarrhoea, I would recommend to I would suggest to withhold food for the next 8-12 hours and then start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice vomiting, lethargy or inappetence.

I'm thinking that you're asking about Immodium - I don't recommend this medication for dogs. In my experience it doesn't necessarily help with diarrhea and it can cause constipation. If the diarrhea isn't uncontrolled I'd just continue the antibiotics prescribed by your vet and wait for lab results. You might want to try feeding bland diet like boiled chicken breast and white rice if Buddy doesn't have any food sensitivities.

As a first and general approach, given that most of these episodes could be dietary related and caused by a colitis (inflammation of the last part of the colon), I would suggest to withhold food for the next 8-12 hours and then start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitively recommend a veterinary check up if the signs persist or you notice more persistent diarrhoea, vomiting, lethargy or inappetence.
