Not Medical Advice: Ring Pops should be fine. However, too much sugar can do the same thing to dogs that it does to humans. It can lead to obesity, dental problems, and possibly the onset of diabetes.
Also, candy, gum, toothpaste, baked goods, and some diet foods are sweetened with xylitol. It can cause more insulin to circulate through your dog's body. That can cause his blood sugar to drop and can also cause liver failure.
Initial symptoms include vomiting, lethargy, and loss of coordination. Eventually, he may have seizures. Liver failure can occur within just a few days.
