How long until I see coat improvements?

Most owners notice improvements in coat shine, thickness, and texture within four to six weeks, which aligns with the natural hair growth cycle.

Can raw eggs hurt my dog's coat?

Raw egg whites contain avidin, which blocks biotin absorption. Cooked eggs are a great biotin source, but raw whites can actually make coat problems worse.

Why is the dose so small?

Biotin is one of the most potent vitamins, effective at microgram amounts. The body also produces biotin through healthy gut bacteria, so a small top-up is exactly the right approach.

Biotin for Dogs: The Beauty Vitamin for Coat, Skin, and Claws

Biotin is the same 'hair, skin, and nails' vitamin you see in every human beauty supplement. In dogs, it supports a thick, glossy coat, healthy skin, and strong claws. It works by helping the body produce keratin, the protein that coat, skin, and claws are physically made of.

The Stylist That Makes the Coat Camera-Ready

Think of all the skin-and-coat ingredients as a fashion show team. Zinc maintains the stage, copper handles colour, B vitamins power the equipment, MSM provides raw materials. Biotin is the stylist doing the final touches, making everything look polished and camera-ready.

One important fact: raw egg whites contain a protein that blocks biotin absorption. Cooked eggs are great for dogs, but raw egg whites can actually make coat problems worse. If you feed raw eggs, cook the whites.

The Science Behind It

Keratin Production

Biotin is essential for producing keratin, the structural protein in coat hair, skin, and claws. Adequate biotin means stronger, more flexible, shinier coat hair that grows faster and sheds less excessively. Low biotin means brittle, dull coats that break easily.

Why Biotin Needs a Team

Biotin gets the marketing credit for coat health, but it works best as part of a complete system. The keratin biotin helps produce needs sulfur from MSM. The skin cells need zinc and B vitamins to divide. The oil glands need omegas. The pigment needs copper. VitaDog includes all of these, which is why results are superior to biotin alone.

Gut Bacteria Connection

Healthy gut bacteria produce biotin naturally as a byproduct. VitaDog's prebiotics and probiotics support the gut bacteria that produce biotin, so the formula supports biotin levels from two angles: direct supplementation and indirect gut health support.

Why It's in VitaDog

Biotin is part of VitaDog's twelve-ingredient skin-and-coat stack, the most comprehensive in any dog supplement. It works alongside zinc, copper, MSM, vitamins A, C, E, niacinamide, riboflavin, pantothenic acid, and omega fatty acids. That depth is why VitaDog produces visible coat improvements that single-ingredient biotin supplements can't match.

What to Look For in a Supplement

Biotin alone won't fix coat problems if the supporting nutrients are missing. Look for biotin alongside zinc, copper, omega fatty acids, and other B vitamins for the best results. A team always outperforms a solo player.
