Tear staining is usually caused by low grade bacteria infection in the tear ducts, normally caused from excess tearing. (Some dogs are prone to it). From my understanding of Tylosin, is that it kills the bacteria infection.
From Angel Glows website..
"Our active ingredient is a macrolide antibiotic considered as narrow-spectrum because it is active against only a few specific bacteria, therefore it will not develop imbalance or resistance in the animal’s immune system."
This is the interesting statement..
"It is important to take the macrolide antibiotic exactly as directed to make sure the infection goes away completely, even if symptoms resolve sooner. Failing to take the macrolide for the entire period can cause the infection to return or can cause the bacteria to become resistant to the macrolide the next time it is taken."
I think that's why it's recommend to keep administering it, for the lifetime of the dog. So if the dog is prone to excessive tearing, you're not allowing the bacteria that's already in the system to build a resistance to it. |
