The 5 Best Water Purifiers to Protect Your Dog From Toxic Chemicals Coming From Your Faucets


Those often-expensive drinking fountains for pets may seem over-the-top, but a water bowl that filters tap water is a good investment in your dog’s health.

Tap water contains a number of toxins that are harmful to dogs. For example, it may surprise you that synthesized fluoride, which is put in the water supply to help prevent tooth decay, is a toxic substance that can reportedly lead to Osteosarcoma, the most common primary malignant bone tumor found in dogs.

Other toxic chemicals in tap water may include:

  • Lead. Large doses can lead to stomach pain, diarrhea and vomiting. Over time, lead poisoning can cause seizures, weakness, extreme anxiety, loss of appetite, blindness, and behavior changes.
  • E. Coli. Sometimes dangerous strains of this bacteria can make its way into our water supply, which can cause a serious infection. Symptoms include vomiting, loss of appetite, dehydration, depression, rapid heart rate, weakness, lethargy, diarrhea, and low body temperature.
  • Calcium and magnesium. These two chemicals are found in hard water. Some states have a greater percentage of hard water than others. The dog health insurance company Trupanion found that hard water leads to urinary tract problems including infections, crystals, cystitis, urinary obstruction, and incontinence.
  • Chlorine. This chemical is added to drinking water, because it is very effective at killing pathogens. That’s great news. But in high doses, chlorine is toxic. In humans, it can lead to asthma, eczema, bladder cancer, and heart disease. In dogs, it can lead to these diseases in a much shorter time because dogs are usually a lot smaller.
