These chicken hearts dog treats are super easy to use. You can simply give them to your dog as a snack whenever they've been good or just need a little pick - me - up. They're great for training too, as dogs love the taste. As for storage, keep them in a cool, dry place. Make sure the bag is tightly sealed after each use to keep them fresh. And always provide plenty of water for your dog when giving them these treats. Just be aware that if your dog has any specific food allergies or health issues, it's a good idea to check with your vet first.
