Our youngest of 4 llamas has been under the weather. She is 8 years old. We have wormed her 2 weeks ago but no change. The vet is on the way over. She hasn't urinated or deficated in 3 days. Her appetite is gone. However, 2 nights ago we let every one run and play in the yard and she munched on grass and trees. She seemed fine for that 30 min period. The vet mentioned tumors and ulcers. I'm a wreck. Our last encounter with a vet was a disaster a few years ago. I'LL TAKE ANY ADVICE YOU HAVE!
