Dog's hives becoming one big hive.
My mini Dachshund was bitten by an yellow jacket, or some other insect, on her muzzle last Sunday. She swelled up all around her face and neck and got hives. This has happened before so followed the vets advice from last time. The swelling went down in a day or so. She was also lethargic, off her feed with soft stools. She now seems to be fine and has returned to her normal eating and activity.
But there was one thing that was new, the individual hives have become one big hive on her back. It is like they merged toghether. I have never seen this before. Should I be concerned?
