Why does my Emi Silkie have two very swollen feet? No puncture wounds or scabs or hard lumps so I’m ruling out Bumblefoot. She is apx 5 years old, no vaccines that I know of as she came from a neighbor. Her identical sister’s feet are fine as are the other 7 big girls. We live just outside of Portland, OR. She has had a round of sulfa type antibiotics and anti inflammatory that did not do a thing. I’m thinking of trying Tylosin next but I thought I would consult the experts here first. My guess is mycoplasma Synovitis? Please let me know what y’all think. Thank you.
