Overview
PetAg Bene-Bac Plus is a milk-flavored gel syringe delivering FOS and lactic acid producing probiotics for dogs and cats, with the title noting use in exotic and wildlife mammals too. It comes as a single 15 g tube meant for direct oral dosing rather than mixing into food.
The gel format sets it apart from powder or capsule probiotics since it's applied straight from a syringe. That makes it easier to dose during a diet change, travel, stress or an antibiotic course, when getting a pet to eat mixed-in powder can be a fight. The listing doesn't state how many doses the tube contains, so check the label for a schedule.
- 0.1 lb net weight
- Gel item form in syringe applicator
- Target species: cat and dog per listing
- PetAg brand, model 99518
Who it's for
Owners of dogs and cats, plus per the title exotic and wildlife mammal caretakers, who want a quick gut-support gel for short-term use rather than a daily maintenance supplement.
