service animal, n.All

A Service animal is useful in breaking veteran's isolation. People will often avert their eyes when they see a wounded veteran. But when the veteran has a dog, the same people will come up and say, 'Hi' to pet the dog and then strike up a conversation.

Service animals have a long tradition --- They were established in Germany during World War I but references to service animals date as far back as the mid-16th Century.

A Service animal is able to raise their masters' sense of well-being.
