My vet had me do the baytril as a nebulizer treatment and it worked well. From my understanding, baytril injections can cause a lot of damage to the tissues and I have read several posts of people that discuss scars from baytril injections. My vet had me do .5 mL baytril in 5 mL saline along with another antibiotic that was injected but I can't remember the name right now. Good luck!
