This happens to my mothers Bassett hound when she needs to have her anal glands expressed. Now she does it for her every 30 days at a groomer but it leaves her backend almost paralyzed until she gets this done then the temp goes back to normal and doggie starts feeling better. You may want to ask your vet about this. Most dogs take care of this themselves by scooting but some dont do it. Or dogs that have a soft stool are also more prone to this issue.
