Diarrhea after dog neuter: Is Diagel a probiotic? Are antibiotics safe?

Updated On September 23rd, 2025

Pet's info: Dog | Maltese | Male | neutered | 1 year and 5 months old | 5.8 lbs

My 5 lb Maltese just had neuter surgery. Two days later he is very sick with chronic diarrhea. After a full day and a half, 7 bouts of it I take him to ER vet. They gave me Metronidazole, Amoxicillin (give every 12 hours of each), 1 dose of Diagel. I called the ER vet and asked about probiotics because the drugs will kill the good bacteria in his gut. They told me on the phone that the Diagel was a probiotic. Is that correct? I can't find any info to support that. Is the 2 antibiotics safe?

Hello. So sorry Niko Denali is having this issue. I would not call Diagel a probiotic but it is a natural product to treat diarrhea. You can certainly use probiotics along with what he is taking if you want to do that but you need to use a product made for dogs. The best probiotic in my opinion is Fortiflora. I would use that one if you can get it. Sometimes you can find it at Petsmart or Petco and even sometimes Walmart has it. If not you can buy it online at Amazon. You do not need a prescription for it. DO NOT use yogurt or products made for people. Dog "good bacteria" and human are not the same. If you can't get Fortiflora quickly enough than you can use any product made for dogs. As for taking the two antibiotics at once, yes, those are commonly given together and work well together. They are safe. Best given with a full stomach. I hope this helps and I hope he is back to feeling better soon! Dr. Amber
