Our Bully is at the vets at the minute and they think he may have Pneumonia.  He is 4 months old.  Just how serious is this and what is the likely treatment?  Anyone know?

Umm depends upon why he's got this.  There are many illnesses that could cause this in one so young.  I would be wanting to know what may be causing this.

Cheers for the reply.  Xrays show he doesn't have it but actually has a narrow Trachea which is affecting his breathing.  Vet says it needs to be monitored and exercise restricted.  Anybody know any further gelp for this?
