Shouldn't hurt. Remember though to keep them within a reasonable amount because they can easily pile on the pounds. For special treats, I used to use cheese slices - breaking off small pieces and rolling into a ball. Dogs love cheese, but, again, everything in moderation
One think you may find is that adult treats tend to be bigger so either break them down or use the ones for small dogs
Thank you for getting back to me! And yes definitely in moderation and especially when I’m training him to learn tricks! Will be fun!!
