Ice cream is not recommended for dogs as it can cause digestive upset. Many dogs are lactose intolerant, leading to gastrointestinal issues, and the high sugar and fat content can contribute to obesity or pancreatitis over time. Some ice creams also contain xylitol, which is highly toxic.
Lactose intolerance causes gastrointestinal upset; high sugar/fat can lead to pancreatitis or obesity; Xylitol causes rapid insulin release and liver failure.
