Indiana is one of the states that has a restraint statute, which means that dogs must be restrained at all times. Otherwise, if the dog bites a person when not restrained the owner is subject to civil liability and criminal penalties. (Cite needed; definition of "restraint" needed; discussion of local Indiana ordinances forbidding dog tethering needed.)
Throw a meat treat in the direction of the oncoming dog, turn on your heels, and walk away. I cannot even count the number of dog owners who are shocked that as their dog is being harassed by the off-leash dog, the owner of stands there, saying nothing, and doesn’t help to put an end to the situation. If another person is walking with you, ask them to attempt to catch the oncoming dog as you leave the scene (you have to decide in an instant if that would be a safe maneuver or not because breaking up a dog fight is an excellent way to get bitten).
Even though your puppy may be learning to walk on a leash very nicely, you’re likely to run into some issues as he gets older, goes new places, and experiences new distractions. You’ll want to teach him loose-leash walking, because it’s much more pleasant for you both, and also then he can pass his Canine Good Citizen test. Here are a few tips on what to do if you’re having trouble with leash training, courtesy of the AKC GoodDog! Helpline.
I mean, have you ever seen anyone successfully loose leash walk their dog using a retractable leash? I observed a man yesterday at our local pet food center trying to control his medium sized dog while another customer was walking their very petite pups. Guess what he was using? A retractable leash, that malfunctioned, the dog was able to get far enough away from the owner that he lost control and the dog went right after those little puppies. Luckily, the dog just wanted to say hello, and those two little pooches knew exactly how to take care of themselves! This scenario could have turned out pretty bad.
