Today, my dog had her tongue hanging out about 2 inches when she was lying in the sun outside. It was not hot out. She did not come in to drink water when she came in the house.
Same thing tonight. Her tongue is hanging out about two inches again.
Is this a sign of something? I should tell you that she has cancer and has recently had a chemo treatment.
This is her first reaction and we took her to the vet, but she had no fever...Just seems like a stomach upset.
