Yes. Apple cider in small doses without additives, sweeteners or artificial flavors can be safe for your pup to drink as it may provide limited nutritional benefits to your dog.  However, you shouldn’t give your dog apple cider if it contains additives, such as sugars, spices, or alcohol, as it can pose severe health risks for your dog. If your fido drinks apple cider with additives, he may experience diabetes, alcohol toxicity, and stomach ulcers. Due to its acidity and bland taste, most dogs may not find apple cider appealing. In that case, you can mix it up into their regular meal or make a dog-friendly treat.
