Dogs can have almond milk occasionally, but it must be free of harmful additives like xylitol or carrageenan. It should be unsweetened and given in moderation due to its high calorie and fat content. Almond milk can offer some benefits such as heart health support from unsaturated fats, skin and coat benefits from vitamin E, and mild digestive support. However, large amounts or regular feeding should be avoided because the fat content can cause digestive upset or even pancreatitis in some dogs. Also, avoid almond milk with artificial sweeteners or flavorings like vanilla, as these can be harmful to dogs.
