Are these treats good for dogs with allergies?

They use only duck and duck liver, with no grains or chicken, so they suit dogs with those sensitivities. They are not hypoallergenic for every dog, so introduce one piece first if your dog has reacted to duck before.

Can I use them as a meal instead of a treat?

No. They are treats, not a complete diet, and should stay a small part of daily calories. At about 5 calories each, a handful still adds up for a small dog.

How should I store them?

Keep the bag sealed at room temperature. Freeze-drying means no refrigeration is needed, but reseal tightly so the pieces stay crisp.

Are they soft enough for puppies and senior dogs?

They are dry and firm rather than soft. Small dogs and puppies can usually manage them, but owners of seniors with dental issues often break pieces in half.

How do they compare with Acana's other treats?

This is the limited-ingredient, single-protein option in the line. Acana's biscuit and jerky-style treats use more ingredients and are usually cheaper per ounce but less suited to elimination diets.
