Hello all. My name is Todd, I have a 14 year old Parson Russell Terrier. She was born deaf, and blind in her right eye. For the past 6 weeks, she's been showing pretty severe signs of separation anxiety. She paces non-stop, and won't let me out of her sight. She paces all day when I'm at work. My vet put her on Xanax. .25mgs/day, which isn't helping. Now she wants to put her on trazadone. She paces so much, she went from 15lbs to 13.5lbs in 4 weeks. Has anyone else experienced this with an older Jack or Parson? I'm so worried about my baby.
