My pregnant dog was fed raw meat, should I give her Pen G antibiotic?

Updated on September 23rd, 2025

Pet's info: Dog | Blue Heeler | Female | unspayed | 45 lbs

I have a pregnant bitch who is starting to get her milk in. I caught my neighbor calling my dogs to her yard and feeding them raw meat. I now have a young female who is fully vaccinated with hemorrhagic diarrhea. She is still eating and acting normal but I wanted to give a precautionary dose of pen g to the pregnant bitch. Is the dosage still 1ml/10lbs body weight?

Hi there! I can absolutely understand your concern about your mama dog. I actually would probably not give Pen G to DJ for a few reasons. 1) the hemorrhagic diarrhea may be from abrupt “diet change” (thanks neighbor) and not from any organism. 2) even if it is from an organism, pen g only works on one of the 4 or 5 organisms I can think of that causes bloody diarrhea. 3) If she is close to labor, it is possible that residual antibiotic in the puppies systems or in the milk could cause diarrhea or yeast infections in the puppy. Instead, I would start a bland diet (1/3 plain cooked chicken, 2/3 plain cooked white rice) and start a probiotic such as Purina Forti-flora. If DJ does break with diarrhea, I recommend a prompt visit to your vet who can help you determine if the benefits of an antibiotic like pen-g outweigh the risks in her particular case.
