You Can Housebreak Your Pup in 7 Days
Google "house break your puppy in 7 days." You'll get a list of sites, books, articles, and blogs, all claiming that housetraining your puppy in 7 (or less) days is a real possibility.
Can You Hit This Target?
No and no. First, the statement hinges on the definition of a housetrained puppy. A puppy is housetrained when he hasn't had an accident indoors in months. So how can a puppy be housetrained in 7 days? You have no measurement criteria. The target goal is unattainable.
If you're reading this and thinking - that's just nitpicking. Okay, if you think so. But then consider this - a puppy is NOT physically ready to control his pee and poop until he's at least sixteen weeks of age. Yes, he might be able to go over night at 12 weeks, but that's because his body relaxes at night. Betcha when he wakes up he screams to be let out of his crate.
Housetraining your puppy in 7 days is near impossible, especially if he's less than sixteen weeks old. The best you can do is to minimize the number of accidents.
