A recent client’s deep subconscious recalled a memory that while in training in the Secret Space Program he was ordered by a Reptilian to kill a puppy and then when he refused, had his abdomen split open, spilling his intestines. Was that an accurately described true account?

This is quite true. The event did happen as retrieved from your client's memory. This was a training exercise and its brutality speaks to the level of spiritual focus you are dealing with.
