More: Theo is training to be my son’s service dog. My son has POTS which can be debilitating at times. Theo is his companion. He goes to the doctor with him. He lays with him when he’s not well. He’s been to a funeral with my son. He’s a wonderful pup and starts training school this week. It will take 2 years before he is fully trained. I am so grateful for this doggo.
