"We have been in hospitals and we see that patients, when they start petting a dog, lower their heart rate and their blood pressure improves," explains a member of an organization that has 130 dogs. Last week they were in Uvalde, Texas, where Wednesday commemorated one year of the attack on Robb Elementary School.
The dogs are "highly trained" from puppies in order to be "trained to respond to a crisis," says Bonnie Fear, project coordinator for Lutheran Church Charities.
