Many dog owners wonder what kind of water should dogs drink — bottled brands like Rosa or Prolom, or plain tap water. Veterinarians often disagree, but Sasha Riess offers a clear and practical answer: The best water for dogs is tap water that has been left to stand.

Why Tap Water Is the Best Choice

Tap water goes through a strict control and safety system. Although many people doubt its quality because of various “conspiracy theories” about chemicals and treatments, tap water actually undergoes rigorous testing to ensure it’s safe for consumption.

To make it even better, let it sit for a few hours — this allows volatile molecules and disinfecting chemicals to evaporate naturally.

“I always prefer tap water — the kind that’s been standing and to which I add a pinch of parsley. That’s the safest water for dogs.” — Sasha Riess

The Problem with Bottled Water

Although bottled water might seem cleaner and safer, it usually comes in plastic containers that go through sterilization processes. These include chemical and physical treatments (sometimes even UV radiation), which can affect the water’s composition. Plastic must be completely sterile to prevent the growth of bacteria, fungi, or pathogens in the water.

However, over time, the interaction between plastic and water causes the release of micro-degraded particles into the liquid. That’s why long-term consumption of bottled water isn’t ideal — for dogs or for humans.

The Ideal Solution — Filtered Tap Water

If possible, use a water filter. It will purify tap water even further, providing your dog with clean, natural water — free from plastic and chemical residues. When considering what kind of water should dogs drink, filtered tap water stands out as the premium choice for long-term health. Clean water supports better digestion, kidney health, and overall vitality. Sometimes, the simplest choice is truly the healthiest.
