Crates

Buy a crate (preferably plastic if you are housebreaking a puppy as they hold in liquid accidents better) and train your puppy to stay in it at night or whenever you cannot supervise him. The average adult female needs a crate 36"L X 24"W X 26"H. Average adult males need 40"L X 27"W X 30"H. Do not put a bed in with puppies as they will chew them up or soil them. For very small pups you can put shredded newspaper in to absorb any accident. With small pups blocking off the rear portion of a large crate helps with those that are over 12 weeks of age and are still soiling the crate. To aid in the housebreaking be sure to set up a feeding and elimination schedule and stick with it. Puppies are physically unable to "hold it" for any great length of time until 3 1/2 to 4 months of age. I do not recommend wire crates for Rottweilers under 8 or so months of age as legs can get caught or pinched between the bars and the growth plates in the front legs can be damaged.

Do not ever leave a collar on any dog in any crate. Many dogs have died when a part of their collar inexplicably got caught on the crate in ways no one could have foreseen.
