Words are not needed to communicate with an animal. They understand and feel so much more than we give them credit for. To exist in life without a spiritual connection to animals is not to fully live.
If you do not walk with the animals, you will not know them. And what you do not know, you will fear. And what you fear, you will destroy.
Connect with a dog or whatever animal calls to you. A hike in the woods or any time spent in nature with them is better than any therapy session and the bond you and that animal will share is worth far more than anything money can buy.
