My dog ate a pig treat and has diarrhea/vomiting. Can I give Imodium?

Considering your description of the signs, Harley may have a possible gastrointestinal infection and require treatment with dietary change (bland diet based on boiled chicken and rice in small portions every 6 hours for 4-5 days), antibiotics, probiotics, antiemetic medications and eventually gastroprotectants. Ask your veterinarian to check her over and discuss these treatment options (on prescription).

I would recommend feeding small bland meals frequently with an added probiotic such as fortiflora. If diarrhea is mild it is often preferred to allow it to be expelled naturally if drinking and alert. Imodium is generally used alongside other treatment or where no signs of infection are identified

You don't mention how many tablets he ate, or how much he weighs. Like all toxicities, Imodium toxicity is dose-dependent, meaning the severity of signs is related to how much was ingested. Dosages of 1.25 – 5 mg/kg can cause vomiting, depression, and salivation. The best way to help him is to get him in to see a vet who can give drugs to control nausea and administer activated charcoal to absorb the rest of the drug in the GI tract. Fluids will likely help him feel better as well.

Withhold food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet (1:1 ratio of plain boiled boneless chicken and plain white rice). Feed in small, frequent amounts waiting at least one hour between feedings. If the vomiting stops, transition slowly to the regular diet. If not or if she develops other symptoms (diarrhea, lethargy, loss of appetite, etc.), see your veterinarian.

It would be best to consult with your veterinarian before changing treatment or giving other medications. Legally, we are prohibited from recommending medications or dosing information in the absence of a physical exam and a patient-veterinarian-client relationship. You can try withholding food for 24 hours. Allow small amounts of water or an unflavored electrolyte replacement beverage. Resume feeding a bland diet in small frequent amounts until symptoms resolve. Transition slowly to the regular diet afterwards. A stool sample should be submitted to diagnose intestinal parasites or bacterial overgrowth. A veterinary probiotic such as Prostora, FortiFlora or ProViable may promote gut health.

Imodium can safely be tried only if a bacterial and parasitic infection has been ruled out or treated for simultaneously. It is possible they are all having an adverse reaction to the dewormer you used. In which case getting them with an antibiotic and probiotic would benefit them more than just the Imodium. I would consider taking 1 puppy out of the litter to the vet to get them tested for any remaining intestinal parasites, and then the recommended treatment above should be considered. In the meantime I would recommend feeding them all a bland diet of boiled plain chicken and rice or cottage cheese to help settle their stomachs. Also over the counter probiotic Culturelle can be started to see if this makes a difference with their stools. Best wishes Witt your pups and I hope you get their loose stool resolved soon. Take care.

This may be a sequel to the medications given. I suggest you fast Maggie for 24 hours and then put the dog on bland food for two days, such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to regular food slowly over a few days. If this does not clear up problem, or if your dog gets lethargic, it needs to see a veterinarian for an exam as there may be something more serious such as an infection going on.
