I have a 1 year old pekin with bumblefoot. She is free range, she first came down with bumblefoot several weeks ago. I treated it then by opening, cleaning and wrapping it and putting duramycin in her water for a couple of weeks. She seemed better, but all of a sudden it is much worse than before. Her leg is hot to the touch, her foot is pretty swollen again and she is limping pretty bad. I am cleaning and wrapping the foot again but I wanted a stronger antibiotic this time so I got injectable Tylan 50. How much should I give her and how many times per day?? And where should I inject it?? Thanks in advance!!
