How digestive and pancreatic enzymes work, who actually needs them, what to look for, and the best supplements for dogs in 2026.
Quick answer: Digestive enzymes for dogs fall into two groups. For a dog with EPI (exocrine pancreatic insufficiency) — a condition diagnosed by a vet — a strong pancreatic enzyme replacement powder like Thomas Labs Bio Case is the standard, lifelong therapy. For general digestive support in dogs without EPI, broader enzyme-plus-probiotic blends such as NaturVet can help during diet changes or mild tummy upset. Enzyme replacement should never be started without a diagnosis, and ongoing digestive problems always deserve a vet visit first.

A high-potency, porcine-source pancreatic enzyme powder that's long been a go-to for dogs with diagnosed EPI, delivering substantial lipase, amylase, and protease to help digest food the dog's own pancreas cannot. The large 2.2 lb size suits long-term daily use; your vet sets the exact dose per meal.

Check price on AmazonGeneral digestive enzyme blends are wellness supplements meant to support normal digestion, often paired with probiotics. Pancreatic enzyme replacement (PERT) is a stronger, medically targeted product for dogs with EPI whose pancreas can't make enough enzymes. They are not interchangeable.
Healthy dogs usually don't. Dogs with EPI — diagnosed by your vet, often with a TLI blood test — need pancreatic enzyme replacement for life. If your dog has chronic diarrhea or unexplained weight loss, see your vet rather than self-treating.
They're typically mixed into moistened food at each meal, sometimes left to sit for a short time before feeding, at a dose your vet sets. Dosing is adjusted to the individual dog and the amount of food, so follow veterinary instructions closely.
General blends are generally well tolerated. Pancreatic enzyme powders can occasionally cause mouth irritation if not mixed properly, and the dose must be managed carefully. Always involve your vet, especially for EPI or any chronic condition.
