Hi Molly’s Mammy and Molly - Welcome!
I’m so sorry to hear about Molly, it must be very worrying for you both.
Sorry I don’t personally have firsthand experience with degenerative myelopathy, but Dr Clemmons DVM, PhD is a great authority on degenerative myelopathy – his treatment protocol is here http://naturallycomplementary.com/community/files/folders/articles/entry1297.aspx . It is very comprehensive, he gives advice on; diet, supplements and lots of tonic herbs that could help Molly. (He’s even done a simplified shopping list with the most important ingredients in bold – very handy!).
Exercise is also important, although this will obviously be hard for Molly. You could consider hydrotherapy as an option that may be easier for her?
The link on this page also has lots of good degenerative myelopathy for dogs info http://naturallycomplementary.com/community/files/folders/success_stories/entry1296.aspx It has a couple of stories about Bear and Dudley who had degenerative myelopathy and benefited from acupuncture and Chinese herbs (keep scrolling down the downloaded page for the stories).
I’d also consider reiki or other energy type work. Healing with energy is also something that you can learn to do yourself (there are lots of books on energy/reiki/ healing in the naturallycomplementary.com bookshop http://naturallycomplementary.com/animal-book-dvd-alternative-complementary-medicine-natural-holistic.html ) and it can have amazing results - never under estimate your own healing power, especially for beloved pets!
Also in the downloads / success stories section, there is the story of Winky the dog and how homeopathy helped him with degenerative myelopathy. http://naturallycomplementary.com/community/files/folders/success_stories/entry1134.aspx
He was prescribed the same homeopathic remedies as Molly. It took him about 3 months for significant sustained improvement – obviously every dog is different and individual – but just to give you an idea.
It must be hugely frustrating for you both and I appreciate waiting for improvements can seem like an eternity, but it does take time to heal and the healing process can be up and down.
Anyway hopefully Winky’s, Bear’s and Dudley’s stories will give you and Molly hope J
Best of luck to you and Molly and keep us posted
Kind regards
Gina
