Put interdigital cysts in the search box at the top of the page. There is lots of information.

Had them in a dog many years ago. The newest procedure, and most effective, was laser surgery developed by an Animal Dermatologist out here in my area. The hair follicles that are causing the development of the cysts need to be layered out. I have a very lengthy article on this study that I can copy and send to you if you like.

My handler recently recommended a Tetley green tea bag sprinkled on my dogs food daily. Since then, no cysts!!!

According to Jean Dodds, could possibly be thyroid related…might want to test…..I do my thyroid testing through her at Hemopet.
