These Natural Balance crunchy dog biscuits are super easy to use. You can give them to your dog as a snack anytime or use them as a reward during training sessions. For best results, break the biscuits into smaller pieces when teaching your dog new tricks. As for storage, keep the biscuits in a cool, dry place. And remember, since this product is going through packaging and formula changes, you might receive either an old or new bag. These biscuits are designed for all life - stage dogs, but if your dog has any special health conditions, it's a good idea to consult your vet first.
