I have been using Ligasano® sponges for the past few months with a great deal of success. I have used it in both dogs and cats with non healing skin wounds or wounds with insufficient skin. I have experienced that these wounds heal 3 to 4 times faster and infection is cleared up a lot sooner. Dirty shearing wounds, dog bite wounds, hyalomma tick bite wounds that go necrotic, puff adder bite wounds where the skin sloughs and becomes necrotic are all examples where I have used these sponges and I had perfect healing in patients every time, I recommend the use of these sponges and I will continue to use them myself, I am astounded at the results.
