Doxycycline is the next best bet. 1st you need to figure out why they are getting respiratory. Ventilation? Humidity? Dust? Damp?I've been using this respitory medication but it doesn't seem to be helping some days there not making a gargly booger noise and other days they are what else can I uses since I'm running out of options!
Doxycycline 80%
Enroflazcin I have been hearing for 2 years now does not work.
