I have a tolblunt polish I keep separate from everyone. I love him dear. He will live in quarantine. He chronically rattles and sneezes. Literally clear him up a day later it’s back. Tylan does nothing. When I say I love him dear, I LOVE AND ADORE HIM. What else can I do. He’s 1.5 years and I don’t want to lose him. Tylan 200 twice a day for five days did nothing. I’ve done Denagard and that does nothing. I have heard about oxine breathing treatments. Has anyone got any suggestions for my sweet boy?
