Our 12y.o. doxie has IVDD and underwent 2 major surgeries in 2018. After physical therapy, laser treatment, and acupuncture she is still weak on her hind left leg. This back brace has been wonderful to keep her back supported as she takes walks and explores the yard. She is continuing to gain strength and build muscle, and I really think the brace has contributed to her general sense of security and support.
