Can Dogs Drink Well Water?

You needn’t worry too much about living in a metropolis because the water there has been filtered and tested. But a private well is the only source of clean water for more than 15% of the population. Is this water safe for dogs even though it might be good for us?

It’s not always healthy for dogs to ingest well water. The reason for this is the possibility of germs, nitrates in wells, or heavy metal contamination of the well.

Additionally, it’s typical for well water to include a lot of minerals, aka hard water, which might be problematic for dogs. However, well water can be suitable for canines when filtered or treated.

Giardia exposure can cause your dog to have moderate symptoms like vomiting or severe outcomes like death. They contract giardia by drinking water contaminated with excrement.

Giardia is a parasite with only one cell that lives in the intestines of animals. Giardia is often spread to dogs via contaminated well water from other animals’ feces. The spread of giardia can be avoided by having your water tested for parasites and bacteria.

The contaminants that could hurt your dog thrive in wells.

The following contaminants are most often known to cause problems in well-water systems:

  • Hepatitis A
  • Giardia
  • Cryptosporidium
  • Campylobacter
  • Shigella
  • Materials like gasoline, nitrate, or arsenic

Earth aquifers can serve as organic filters for well water; however, they cannot remove all contaminants before a dog drinks from a well.

There is also a chance that run-off will affect your well water if you reside on a farm or close to any form of industry.  As a result of cleaning agents and chemicals seeping into the groundwater, drinking it could pose a risk.

What type of water is best for dogs?

Tap water is the greatest option for your dog. It is less expensive than constantly purchasing bottled water, includes all the essential nutrients and minerals, and doesn’t carry the same danger of contamination as well water.

Finding strategies to ensure your dog remains hydrated is important, as dogs require the same amount of water as humans. Since a dog’s body contains more than 70% water, much like a human’s, water is as important to dogs as it is to humans.

It might be challenging to locate the ideal water source for a dog. You may be tempted to allow your dog to drink from standing water if you live close to a lake, pond, or other body of water. However, a dog can suffer great harm from standing water.

Despite its seeming safety, distilled water is deficient in the minerals dogs require for proper hydration. It’s better only to offer your dog modest amounts of distilled water.

Frequently Asked Questions

Can well water give dogs diarrhea?

Yes, different bacteria and microbes present in the environment can induce stomach problems in your dog. Additionally, this can cause problems with the neurological system and the urinary system.

Can dogs drink bottled water?

Many advise against giving bottled water to your dogs or even consuming bottled water yourself. Bottled water has detrimental environmental effects and includes toxic substances like BPA. We do not prescribe bottled water since BPA has been linked to cancer and hormone problems.

Can dogs drink too much water?

If dogs consume too much water, they could become ill. This occurrence is typical, particularly throughout the summer. Getting unwell after consuming too much water frequently indicates a more serious condition. In this situation, we advise seeing your veterinarian.


The well water could contain several dangerous contaminants that make dogs ill. It presents an excessive danger that might eventually result in serious illnesses.

When it comes to your dog’s health, don’t skimp on the condition of your well water. It would be best to get the water tested frequently, utilize a softener, or invest in a whole-house filtering system to ensure your pet’s safety.

Provide your dog with enough fresh water daily to avoid dehydration. Consult a specialist if you’re unsure about the caliber of your well water.
