After all, if you're practicing a technique incorrectly, and doing it a lot, all that means is that you're going to be really good at doing something wrong.
When I was a wrestler in high school, every practice started by drilling basic techniques like a double leg take-down. We learned quickly on a match day that if we had drilled sloppily, our double leg take-downs weren't going to magically work in a live situation.
It's summer time and a great time to train. If your dog has an issue you're working on, or you just want your walks to be pleasant, get training now! Your dog will thank you and appreciate it.
Remember, practice doesn't make perfect - perfect practice makes perfect.
