This has happened twice in the past two months. I dropped my female, 1 year old, spayed dog off at the boarder for a week. When I picked her up, she was lethargic (just laying down), hot and sweaty, and had a runny nose. I think her breath smells mucusy, like a human's when they have a cold.
The first time, this went away after a few days. I attributed it to being in close continual contact with many other dogs, for the first time in her life. But, I just picked her up today, and it's happened again.
This boarder has "open" boarding. They don't crate them, but rather let them run around in an indoor area with a concrete floor all day. I assume they sleep on that floor. The boarder is staffed 24/7. The workers seem nice. The place has good reviews online.
Is this normal? Would a dog often get sick after a week of boarding (continual play, exposure to other dogs, sleeping on the floor)? Might she have been too cold at night? Or could something be wrong?
Edit: She's lethargic for a few days after coming home from the kennel, both times I've left her there for a week. It's strange because, we can watch her on the webcam playing and having fun, which she seems to do often.
