Should I worry about a soft sac under my dog's chin after steroids?

Updated On September 23rd, 2025

Pet's info: Dog | Australian Shepherd | Female | spayed | 9 years and 11 months old | 35 lbs

Our Australian Shepherd was not well. Vet thinks MIGHT be MMM. Nothing major out of whack w usual blood work, no fever, teeth/gums look OK. On steroids for day 6 now. Little improvement, but now I notice this soft flabby "sac" under her chin/jaw/neck. Hard to notice unless she is standing and it is hanging down. Lotz of thick fluffy fue in that area. Should I worry or is the muscle "releading" or softening or shrinking bc of steroids?

Hello, sorry to hear about Chessie. It sounds like she could be having loose skin on her neck which some dogs commonly get. However, other skin swellings in that area could indicate a swollen lymph node or salivary gland. An abscess could form there as well. Theses are commonly firm, and more frequently painful than not. Muscle that weakens with the use of steroids does not typically hang or sag, it just becomes smaller. If Chessie is not painful and this skin seems like excess skin and not a formed mass or swelling, then you may continue to monitor her at home. If you note any pain, excessive salivation, difficulty swallowing, or a decreased appetite, then have her evaluated immediately. Hope this helps and best of luck.
