That's what I was afraid of. How long after infection do symptoms like that show up? The reason I'm asking is that Layla hadn't really been out of the house much for the past two weeks, but we were at puppy class on Wednesday. I'm wondering if she might have gotten it from another dog at classes, or if she could have gotten it a few weeks ago and just not had symptoms until now? And she could possibly have infected other dogs at the classes? I'm a little stressed out now
I guess I'll call the vet in the morning and try to get her in to find out for sure.
