Like most treats, ice should be given in moderation. This might look different for each dog depending on their size and how well they can safely tolerate ice, meaning they don’t aggressively chew it or gobble it up too quickly. In general, a few small ice cubes or a few spoonfuls of crushed or shaved ice a day should be fine, but consult your vet for personalized advice. Like most treats, ice should be given in moderation.
