Reddit mentions of Chuckit Fetch Ball Medium (2 Pack)

If you're going to crate the dog, then I suggest this crate. It has a divider so that you can make the crate small for when he's a puppy and then slowly move the divider as he gets larger. As long as the crate has only room enough for him to turn around and lay down then he will not poop or pee in the crate. Fill the empty side of the crate with some cardboard boxes so that it feels small and cozy. This is by far the best way to potty train a dog. This crate size is perfect for my 93lb 4 year old and he has plenty of room in it to stand up and sleep in multiple positions.

Do not get him bedding with stuffing. He will most likely destroy it, eat the stuffing, and get blockages (same with stuffed toys). Mine did this to all his beds but luckily he pooped out the stuffing. Instead, I got him a big white IKEA comforter. It's a like a big blanky he can move around to his desire and he won't destroy it. Also, it's easy to toss in the washer.

Buy a Kong so you can stuff peanut butter, cheese, and other treats into to keep him busy.

These are the best dog balls I've found. My dog can't destroy them and he loves playing with them:

Also, do NOT cheap out on his food. Buy 100% grain free high quality food. Dobermans are subject to getting bloating and foods with grain can cause it which can lead to death. I suggest Taste of the Wild's Salmon puppy formula.

Lastly, socialize this dog like crazy. Take it everywhere and have it meet all sorts of people, dogs, animals, city life, etc. At first, though, since he doesn't have all his shots you might have to just stick to puppy classes where other dogs have their shots (so no one catches any illnesses). Don't take the puppy to random dog parks as they can be filled with diseases which your puppy isn't protected against.

Good luck!

Seconding the Chuck-It! durable balls; the orange and blue ones. Although my guy isn't much of a chewer when it comes to tennis balls, some of the pups I dog walk snap the balls in half, and then they become a choking hazard and unusable. Have literally spent upwards of $500 trying different kinds--squeaky, regular, various colours and brands--and these are the only ones that have lasted, and they show ZERO signs of wear, plus they make a cool whistling sound when thrown! These, along with the Chuck-it thrower, are lifesavers for eliminating slobbery hands and sore arms.

I sound like a Chuck-It rep, but I'm just so psyched about their products!

I know you said no balls, but one of our guys loves Chuckit balls. When he isn't just chewing on it, he'll push it around with his nose and make it fall off of the couch and down the steps then chase after it. And these things are indestructible. They make a bunch of different types, but his favorite is the original. We got the medium size and it's perfect.

If you have room for her to run, invest in the chuckit ball launcher. It makes throwing the ball so easy (and you don't have to get your hands all slobbery!)

It's the rubber "Fetch" ball that Chuck-it makes. We have only lost these balls due to snow drifts, not teeth.
