It would also have to be frozen pretty cold, -4 for at least a week to kill any fluke carrying the bacteria that is harmful to dogs.  My upright doesn't get that cold but my chest freezer does.

I would keep it in case I ran out of better eggs and then throw it into crab or shrimp bait next year.

Now watch.....   you're gonna catch a 20 Lb. Steelhead on them.
