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?
