Piper had his annual exam today. He is 11 years old, and thankfully in seemingly good health. We await the senior blood panel to confirm. We recently found a strange type of spot on his eyeball. Being 11, we assumed it was a part of the aging process. While Doc did say it's due to aging, he believes it's a cholesterol deposit caused by a possibly low functioning thyroid. Who knew?! We will either confirm or eliminate this with test results. The good news is, it does not affect his vision. Yay! So, sharing the news in case anyone out there finds something similar with their own pups. Could be signaling a thyroid disorder.
