I’m confused - there was an alien-in-the-freezer story, too.
Anyhow, the bigfoot one reminded me of ‘The Creature in Ice’. I saw this at a shopping mall around 1970; I remember it smelled like vomit, and I didn’t know if that was another little ‘touch’ added for effect, or if someone had gotten sick looking at it - LOL!:

No you’re right. It was an alien (in the Cascade Mountains) that killed the guy’s dog and he “killed” the alien and put it in his freezer. But then the alien wasn’t killed, just knocked out. IIRC the story ends with a bunch of black suv’s loading the alien and the freezer up and whisking it away.
I seem to recall seeing that monster in the ice thing too. I grew up in Minnesota in the 70’s. Later on I recall seeing the remains of a baby mammoth from Siberia on display - and advertised as such.
