I had a vet tell me not to give acv when giving meds probiotics or vitamins. Might want to give them regular water while you worm etc.
That would be to prevent the two from contaminating each other. Otherwise, the ACV and antibiotic, etc. are fighting each other. The wormer is topical, so no worries about that. Thanks so much for the info, though. It's good to know someone had my back!
