Dextrose is the first ingredient in Petralyte Dog Formula. It activates the sodium-glucose co-transport pathway (SGLT1)—the same mechanism behind WHO oral rehydration therapy—to help support efficient fluid and electrolyte absorption.

Our dextrose-to-sodium ratio is close to 1:1, aligning with WHO ORS ratios, so the absorption story is grounded in established rehydration science.

Potassium is one of the main electrolytes needed in a dog’s body and plays an important role in everyday body processes.

It helps support fluid balance and proper muscle contraction. Maintaining adequate potassium is especially important during activity, warm weather, or times when dogs lose fluids faster than they replace them.

Calcium is an essential mineral that helps support healthy muscle function, nerve signaling, and overall electrolyte balance in dogs.

Petralyte includes calcium as part of an optimal ratio of key electrolytes to help support hydration and daily wellness.

Magnesium helps support normal muscle and nerve function and works alongside other electrolytes to help maintain fluid balance.

It is an important part of a complete electrolyte profile for active dogs and everyday hydration support.

Sodium works with dextrose through the SGLT1 pathway to help support water and electrolyte absorption—a core principle of oral rehydration science.

Together with potassium and calcium, sodium helps support balanced hydration for dogs before, during, and after activity.

Fructose is retained in a smaller amount for palatability—dogs taste sweet, and dextrose is less sweet—and for its lower glycemic impact.

It is no longer the primary carbohydrate in the formula. Dextrose now leads for absorption science, while fructose plays a supporting role.

L-Glutamine is an amino acid that supports the intestinal lining and gut health. In Petralyte, it is paired with Zinc for enhanced gut and immune support.

It also helps support muscle recovery and energy after activity or times of stress.

Glucosamine helps support mobility, joint comfort, and cartilage health.

It is a key joint-support nutrient for dogs of all ages, breeds, and activity levels.

Chondroitin Sulfate works alongside Glucosamine to support mobility, joint comfort, and cartilage health.

Together, these nutrients help support hip and joint wellness as part of Petralyte’s daily formula.

Taurine is an amino acid that helps all muscles function better. Since the heart is the most important muscle in your dog’s body, Taurine is vitally important in promoting cardiovascular health.

Taurine is also needed to help keep your dog’s eyes healthy.

Zinc works with L-Glutamine to help support gut health and immune function.

It is part of Petralyte’s immunity and digestive support profile, working alongside essential B vitamins and prebiotics.

Thiamine HCl (Vitamin B1) and Pyridoxine HCl (Vitamin B6) are water-soluble vitamins that can be lost during dehydration.

These essential B vitamins help support energy metabolism and immune function, working alongside Zinc and prebiotics for comprehensive immune and vitality support.

Oligofructose is a prebiotic that helps support healthy gut flora.

Together with Inulin and L-Glutamine, it is part of Petralyte’s stomach and intestinal support profile to help maintain digestive wellness.

Inulin is a prebiotic fiber that helps support healthy gut flora and digestive balance.

Paired with Oligofructose, it helps support gut health as part of Petralyte’s whole-body formula.
