"If you have a blind dog, you have no other option to help their quality of life than getting a Muffin's Halo for your furbaby! Our dog Sasha went blind suddenly (the condition is called SARDS) and Muffin's Halo prevents her from smashing her skull into furniture constantly. The Muffin's Halo is like a bumper for her head, just giving her the slightest resistance to move her away from danger. It's an amazing product and I'd literally be in the funny farm if it weren't for Muffin's Halo. Do not accept imitators...this is the real deal, made with love by Silvie and her team. She is doing amazing work and I can't thank her enough for improving Sasha's golden years. Read the Muffin's Halo site and see what a labor of love this is. I've spoken to Silvie several times by phone and she is passionate, compassionate, and the most empathetic person I've ever "met." Thank you, Silvie and Muffin!
