That's a bit steep CG,i can get it for £10 a bottle,intermuscler.I think myself that salt and water is ok to wash a wound but not good enough to fight infection,you can just imagine what a hungry fox would be pulling at that's why i like to get some type of antibiotics into them.I also use synulox and betadine wash,very good for healing a dogs wounds,also alamyson spray,then everyone has a different way of doing things.
