Question: Does Eating Snow Equal Drinking Water?
Answer: Absolutely not.
The truth is that eating snow requires a tremendous amount of energy, and body heat to melt the snow in the first place, and the amount of water is several times LESS than the amount of snow was originally. A bucket of snow will melt down to a very tiny amount of water.
Snow Poisoning is a recent term for a dog who is essentially dying of thirst, surrounded by snow. It is extremely important to ensure that your dog has fresh water available at all times. There are heated water bowls available to prevent freezing and allow ease of drinking, even in the coldest temperatures. A dog needs more water in the winter as his body expends more energy in just keeping warm. Of course you should always have fresh water available in the house as well.
