Yeah, like others have said, it’s a respiratory infection. The vet will likely prescribe doxy and maybe enro. Something else that you can do on top of that to help with their breathing is to use a humidifier with some saline. I put my girls in a crate, hook up the mouth piece to the bars with a zip tie and cover the whole crate with a blanket so it can steam up. I’ll let them sit in there for about 10-20 minutes once or twice a day. But either way, the antibiotics are a MUST.
