Product Description
When a dog or cat has acute diarrhea, the priority is fast resolution — not a supplement that takes weeks to work. Diarrhea depletes electrolytes, disrupts the gut's microbial balance, and damages the intestinal lining. An effective acute intervention needs to address all three: binding and neutralizing toxins in the gut, replenishing lost minerals, and supporting recovery of the intestinal barrier.
Entero Aid +GI by Grey Wolf Animal Health is a liquid GI supplement designed specifically for acute digestive episodes. Where Fibre Boost +GI and Pro Care+ GI are built for daily maintenance and microbiome support, Entero Aid +GI is the acute-phase product — concentrated, fast-acting, and easy to administer to a pet that may not be eating normally. Distributed in Canada by Grey Wolf Animal Health and manufactured by Cf Pharma, Entero Aid +GI is authorized for sale by Health Canada as a Veterinary Health Product (NN.K5L1).
The centrepiece of the formula is montmorillonite at 400 mg per mL — a medical-grade clay with a strong adsorptive capacity. Montmorillonite binds bacterial toxins, endotoxins, and other irritants in the gut lumen, preventing them from damaging the intestinal wall or being absorbed systemically. Clinical evidence supports its use in reducing the duration of acute diarrhea in companion animals. At 400 mg per mL, Entero Aid +GI delivers a meaningful therapeutic dose in a small liquid volume.
The electrolyte component — sodium chloride (30 mg/mL), potassium chloride (6 mg/mL), and magnesium chloride (6 mg/mL) — addresses one of the most immediate concerns during diarrhea: fluid and mineral loss. Diarrhea causes rapid depletion of these electrolytes, which are critical for normal cell function, muscle activity, and hydration. This makes Entero Aid +GI useful not just for resolving the diarrhea itself but for supporting the pet's overall condition while recovery takes place.
L-Glutamine (2 mg/mL) provides targeted support for the intestinal epithelium. The cells lining the gut wall use glutamine as their primary fuel source, and during periods of GI stress these cells are under increased demand. Supplementing glutamine helps maintain the integrity of the gut barrier — reducing the risk of bacterial translocation and supporting faster mucosal recovery. Enterococcus faecium DSM 10663/NCIMB 10415 at 49 million CFU per mL rounds out the formula with a clinically studied probiotic strain to help re-establish healthy gut flora as the acute episode resolves.
The liquid format is a practical advantage when a pet is unwell. Many dogs and cats will refuse food during GI upset, making powders and chews difficult to administer. Entero Aid +GI can be given directly by syringe or mixed into a small amount of food, making compliance easier during the most critical phase of an acute episode. Three sizes — 15 ml, 30 ml, and 60 ml — allow for appropriate supply based on pet size and anticipated duration of use.

Supplement Advisor's Note
Entero Aid +GI occupies a specific and important role in the Grey Wolf GI line — it is the acute-phase product, not a daily maintenance supplement. The montmorillonite clay at 400 mg per mL is the key differentiator: clay-based adsorbents work mechanically rather than biochemically, binding toxins and irritants in the gut lumen without being absorbed themselves. This makes the effect fast and predictable regardless of the pet's microbiome status. The electrolyte combination is a thoughtful addition — sodium, potassium, and magnesium are the three minerals most rapidly depleted during diarrhea, and replacing them supports both recovery and general wellbeing while the episode resolves. For a pet currently in acute GI distress, this is the right starting point; Fibre Boost +GI or Pro Care+ GI can be introduced once the acute phase has passed for ongoing microbiome and gut health support.
FAQ
Q: How is Entero Aid +GI different from Fibre Boost +GI and Pro Care+ GI? A: The three products serve different phases of digestive care. Entero Aid +GI is designed for acute GI episodes — it acts quickly using medical-grade clay to adsorb toxins and electrolytes to support hydration. Pro Care+ GI (sachets) focuses on rebuilding the microbiome with probiotics and prebiotics, making it ideal during and after recovery. Fibre Boost +GI is a daily maintenance supplement for pets with chronic stool quality issues, sensitive stomachs, or anal gland problems. All three can be used together or sequentially.
Q: Can I give Entero Aid +GI at the same time as antibiotics? A: Yes, but timing matters. Montmorillonite clay can adsorb medications in the gut, potentially reducing their absorption. To avoid this interaction, separate the Entero Aid +GI dose from any oral medication by at least 2 hours.
Q: How quickly will I see improvement? A: Many pet owners notice stool firming within 24–48 hours of starting Entero Aid +GI. The clay acts quickly to adsorb toxins and normalize gut transit. If diarrhea persists beyond 48–72 hours or is accompanied by blood, lethargy, or vomiting, consult your veterinarian.
Q: Which size should I choose? A: The 15 ml size is well suited for cats and small dogs or for short acute episodes. The 30 ml is a practical choice for medium-sized dogs or households with multiple pets. The 60 ml is best for large dogs or when a longer recovery period is anticipated. All three contain the same formula at the same concentration.
Q: Is Entero Aid +GI safe for kittens and puppies? A: Consult your veterinarian before use in very young animals. The formula is gentle and does not contain ingredients that are inherently unsafe for young pets, but appropriate dosing for kittens and puppies should be confirmed with a vet.
