Can Dogs Drink River Water?
Ensuring your dog stays well-hydrated is essential for their health, preventing dehydration and overheating, and supporting their overall wellbeing. Providing fresh, clean water regularly and maintaining clean bowls helps your dog benefit fully from their diet and enjoy daily life. Whether at home or out walking, always have fresh water readily available for your dog, offering it regularly, especially during exercise or warm weather.
While you may encounter natural water sources such as streams, canals, or ponds while outside, these are often unsafe alternatives to fresh water. It’s equally important to discourage your dog from drinking from puddles or unknown water sources during walks.
In this guide, we explore six water sources your dog should never drink from, explaining why and how to protect your pet effectively.
1. Snow or Melted Ice
Despite the tempting coolness of snow or ice, it is generally unsafe for dogs to eat or drink. Snow and melted ice can carry harmful pollutants, antifreeze, gritting salt, or other chemicals harmful to pets. Additionally, cold water can dangerously lower your dog’s internal temperature, especially if consumed in large amounts. Dogs that become accustomed to picking up ice may mistakenly chew glass shards, risking injury or cuts. The only exception is adding clean ice cubes from your freezer to your dog’s water bowl on a hot day, which is safe and refreshing.
2. Stagnant Ponds and Pools
Water that remains still, such as in ponds or pools, is a known breeding ground for bacteria, parasites, and toxic organisms. Runoff from fertilisers or pesticides contaminates these waters, and dangerous algae blooms like blue-green algae can be fatal to dogs. Even if a pond looks clean, it can harbour illnesses like leptospirosis or gastrointestinal infections. It’s safest to avoid letting your dog drink from these sources completely.
3. Salt Water
Salt water from seas and oceans is highly unsuitable for dogs. Drinking seawater can rapidly dehydrate your dog further and cause symptoms like vomiting, diarrhoea, or other salt toxicity effects. While a day at the beach is wonderful for dogs who love to swim, always carry fresh water with you to offer your dog to drink instead. Some beaches have fresh water taps, but never rely solely on their availability.
4. Dirty or Stale Tap Water
Tap water per se is safe for your dog, but once it sits out for a long time or if the bowl is unclean, it can carry bacteria or contaminants. Change your dog’s water at least twice daily, wash the bowl with hot water frequently, and never refill a dirty bowl. When out walking with bottled water, replace it regularly and avoid letting your dog drink from older, stagnant water in bottles or bowls. Also, ensure toilet lids are always closed to prevent your dog from drinking toilet water, which may contain harmful substances.
5. Chlorinated or Treated Water
Chlorine is used in tap water and treated water bodies to control bacteria and algae, but chlorinated water in pools or garden ponds often contains chemicals that are unsafe for dogs. Drinking from swimming pools, hot tubs, or fish ponds treated with chemicals can irritate your dog’s digestive system or cause toxicity. If you are unsure about the water’s safety, always avoid it.
6. Puddles
Many dogs may drink from puddles while on walks, attracted by recently fallen rain. However, the ground around puddles can contain dirt, chemicals, bacteria, and parasites that put your dog at risk of illness. Whilst you can’t always stop your dog from drinking from puddles, carrying fresh water and offering it regularly helps provide a safer alternative.
Keeping Your Dog Safely Hydrated
To keep your dog healthy and hydrated, always prioritise providing fresh, clean water from safe sources. Especially outdoors, carry water and a portable bowl and offer it frequently during exercise or hot weather. Additionally, prevent access to questionable water sources like stagnant ponds, puddles, or saltwater. Regular cleaning of bowls and water containers at home is key to good hygiene.
If you are considering a new dog, be sure to obtain them from reputable breeders or adoption centres to ensure responsible ownership and health considerations are met.
By taking these practical steps, you help safeguard your dog's health and wellbeing every day.
