No, it's only injectable Baytril that causes the irritation and fur loss.
Yes, I did believe you/your vet was talking about something systemic - as was jerseygirl and myself.
A vaccination can also cause some hair loss around the site, as can (as I mentioned) other injectables
Thanks. Not quite sure myself what is covered by "systemic", presumably anything that affects the entire system ?
Shame it is only the Baytril injections. I was hoping that might have been a possible explanation and that he would recover as it had now been stopped.
Is it worth doing other investigations in your experience: e.g. blood tests, xrays ? Our vet said those could be done but they would probably not be able to treat whatever was diagnosed so little point.
