To Sum it up!

If your dog’s attack is not tackled quickly and appropriately, the problem can escalate. It may result in serious injury to yourself and your family, other people, or other animals, and even legal issues – and of course, you want to get help for your dog long before it goes that far! Proactiveness is a far better problem – and far easier – tackled immediately!
