Since they is also a respiratory infection, there may be more going on than bumblefoot, such as mycoplasma synovitis, which Tylan would work for treatment. But I do think that a vet should be consulted, since other antibiotics could treat both staph infection or MS/MG. I agree about doing bumblefoot surgery, but this seems more serious, requiring a vet.I don't believe the tylan would help with the bumble foot. The swelling will not go down until the corns under each scab have been removed. Sometimes you can soak and squeeze them out but larger ones need to be taken out surgically. Afterwards a topical antibiotic can be put on and the foot wrapped. Do a search for bumble foot surgery.
