DOG by Dr Lisa Fibre is an organic fibre supplement for dogs, formulated by Australian veterinarian Dr Lisa Chimes to support digestive regularity. Available in a 100g powder, it helps regulate bowel movements and supports overall gut health through a combination of fibre, prebiotics, postbiotics, and paraprobiotics.

The supplement is designed to work in both directions — firming loose stools and softening overly firm ones — making it broadly useful across a range of digestive presentations. The prebiotic, postbiotic, and paraprobiotic components support the gut microbiome alongside the fibre action. It is certified organic and intended for daily use mixed into food.

Dogs with chronic loose stools, irregular digestion, or owners simply wanting to maintain gut health are the typical users. The vet formulation and organic certification make it a popular choice for owners who want a supplement they can trust.
