It is not advisable for dogs to eat frozen yogurt.
Frozen yogurt is a dairy dessert consisting of milk solids, sweetener, milk fat, yogurt culture, flavourings, and colourings. Different from plain yogurt, it usually contains more sugar and additives to help create its consistency and extend its shelf life. Plus, some commercially sold frozen yogurt are higher in fat compared to regular ones.
Though frozen yogurt may have probiotic benefits that could aid with your dog’s digestive system, the other aforementioned ingredients may not be good for him. Sugar, for example, can cause upset stomach, inflammation, vomiting, and diarrhea. Regular consumption of frozen yogurt high in sugar and other artificial flavourings can also cause dental problems, weight gain, and obesity.
What to do if your dog accidentally eats frozen yogurt: If your dog accidentally takes a lick of your homemade frozen yogurt, no problems should arise if all the ingredients used to make it are non-toxic for canines. A small taste should not cause major digestive issues. But lactose-intolerant dogs who eat a substantial amount in one go may experience gas, diarrhea, and flatulence.
Contact your vet immediately if harmful ingredients such as chocolate, certain nuts, and alcohol are in the frozen yogurt. Similarly, avoid commercially bought frozen yogurt, especially those served in various flavours and overloaded with toppings. Also, be cautious of giving him sugar-free frozen yogurt. The artificial sweetener xylitol may be present, which is highly toxic to dogs.
In summary: Though it may be tempting to let your dog try frozen yogurt, it should not be done on a regular basis. Gastrointestinal problems, food allergies, obesity, and diabetes may develop depending on the ingredients of the frozen yogurt he consumes.
