Reddit mentions of Adolph's Unseasoned Tenderizer, 44.5 oz, White

You could purchase a second, identical crate to put in his pen. To ensure no accidents got through to the floor (puppy would pee on the pad, but sometimes it'd be at the very edge of said pad, or would dribble as she walked), I ended up layering a cheap, waterproof shower curtain and cute toddler water repelling food/splash mats. My puppy kept playing with her water bowls and making a mess everywhere, so I ended up getting something like this, but nicer. To prevent puppy from eating said poop if he goes while you're gone, you can put a small amount of this in his food - it's a life saver!

A good chew might be good; I purchased a giant bag of bully sticks at costco that my dog absolutely loves chewing on, and it's probably going to last for 3 years at this rate (and is much more bang for buck than buying individual sticks or small bags at other stores). I don't leave food in there all day, so I can have a better idea of when my puppy poops and pick it up immediately. Depending on your pen, you may need to DIY a lip or covering for the pen before your puppy learns how to jump out.

Here are a couple of tips I would suggest to mellow the meat out as well:

1. Get a Jaccard tenderizer. Worth it's weight in gold. It has 45 little knives that you use to tenderize the meat, and it works very well.
   
   
2. After using the Jaccard, sprinkle on tenderizer powder. You can usually buy it in smaller shakers at the grocery store in the spice aisle.
   
   We cut the meat into the sizes we want to cook it, Jaccard it, then sprinkle with the tenderizer. Then, we put it back in a bag in the fridge for a bit. That way, it isn't so tough when you cook it. Also, we like to marinate deer meat in Italian dressing. Tastes great.
