The vet came out today. She looked at Isis’ belly and took samples to send off to the lab. We opted to do a biopsy of the area. The biopsy should tell us if it is an infestation of some sort, allergies, rain rot, or something else.
Isis was really good for everything. She was sedated (poor woosie mare), and she had three staples where the biopsies were taken. It didn’t take that long to do the biopsies — maybe 30 minutes total?
The vet said it will take about a week for the results to come back.
