Here's why:
* Toxicity: While glycerin itself is not generally toxic to dogs, it can cause digestive upset, especially if consumed in large quantities.
* Unnecessary: Glycerin offers no nutritional benefits for dogs, and there are no proven health reasons to add it to their water.
* Risk of Overconsumption: Dogs can be unpredictable drinkers, and adding a substance like glycerin to their water could lead to accidental overconsumption, potentially causing side effects.
Instead of adding glycerin, focus on providing your dog with fresh, clean water.
If you have concerns about your dog's health, consult with your veterinarian. They can provide personalized advice based on your dog's individual needs.
