My dog, Mason, started to hypersalivate dry gag/vomit on Saturday, 8/30/25. I took him to a 24/7 veterinary hospital per my vet's recommendation. He was given anti-nausea medication and fluids. Unfortunately Mason was still hypersalivating on Sunday, 8/31, so I brought him back in to the same emergency vet. X-rays showed an enlarged/bloated stomach, an enlarged esophagus (termed megaesophagus) as well as a mass near his lungs.

The mass was diagnosed as a thymoma, a benign cancer of the epithelial cells of the thymus. The vets recommended surgical removal of the thymoma, which was the main issue and likely the cause of the dilated esophagus (megaesophagus).

I was told that removal of the thymoma had a 50% chance of leading to resolution of the megaesophagus, which would be ideal. If the megaesophagus does not resolve, he will need to be fed with his esophagus close to vertical (standing on his hind legs like a person) while eating, and for 15 to 30 minutes after eating. It's a manageable condition, but I'm hoping that the removal of the thymoma will allow his esophagus to heal.

So far the total cost of care during these 2 admissions, including thymoma surgery, has totaled approximately $25,000. Unfortunately my pet insurance may only cover up to $10,000--and only for approved expenses.

Any amount you can donate to his surgery and recovery would be much appreciated.
