Also don't forget he's teething so he needs some relief. For some odd reason I think our hands and arms feel great to teething puppers! You can get old washcloth wet and freeze it and let him chew on it for a little while. It will help soothe his achey gums. Also you can get a kong and fill it with peanut butter and freeze it.
I also am sure I don't need to mention this. But I'm not sure where you live but if Zeus is gonna be an outside only dog please make sure to have a good shelter for him, i.e a dog house and if you live somewhere where it gets really hot you might want to put a swamp cooler or ac unit in it. And make sure there is plenty of water out for him! Sorry, I'm not a fan of outside only dogs but if people insist I just want to make sure they have the dog out in best possible situation.
Cheers,
Julie
Also, HW preventative is KEY if you are going to keep the dog outside!
Another thing to consider is that he's a puppy. Puppies have lots and lots of energy, so the best way to burn that off is good ol' fashioned exercise. Take that puppy for walks, throw balls and sticks, etc. A puppy with lots of energy left cooped-up with no outlet for that energy is just a mess waiting to happen.
My friend has a full-grown male Rottie. He never appropriately dealt with his energy as a pup (left him tied out all the time) and now he has a dog that he can't have around his two young daughters. Rocco is sweet, but a MESS.
