Frequently Asked Questions
- Blueberries earn their superfood reputation honestly. They contain one of the highest antioxidant levels of any common fruit, including anthocyanins and resveratrol that may help combat cell damage. They're also low in calories, making them one of the few fruits you can offer multiple times per week without disrupting your dog's calorie balance. Veterinarians often recommend blueberries as a healthier alternative to commercial training treats, especially for overweight dogs. That said, they should still be a supplement to a balanced diet, not a replacement.
- Yes, puppies older than 8 weeks can have blueberries in small amounts. Start with one or two berries to confirm there's no digestive upset, then gradually add to their treat rotation. Halve or mash the berries for very small puppies to avoid any choking risk. Keep all treats — including fruit — to under 10% of daily caloric intake, and never substitute blueberries for the balanced puppy food they need for proper growth and development.
- Frozen blueberries are an excellent treat, especially in summer. The cold is soothing for teething puppies and refreshing on hot days. Buy plain frozen berries from the freezer aisle — never the kind packed in sweetened juice. For small dogs, let them thaw for a minute or two so they don't damage teeth or get stuck in tiny throats. Some dogs love them rock-hard; others prefer them slightly softened. Either way, they make a low-calorie, mess-free training treat alternative.
