I used this on a street dog in my area. It had a deep cut (about half inch wide & 3 inch long) on its neck - and puss was coming out of it. Looked quite horrible initially. I sprayed this 3 times over a week (whenever i could spot that dog) - and a few days later - i saw that the wound was healing nicely (there was a dry layer formation on the wound). I would highly recommend this product.
One thing i noticed - while running around the street - trying to apply this spray on that street dog trying to get away from me (but luckily it was a bit calm & didn't growl when i got closer) : The spray jet from the can will come out with pressure only when the can is held upward (like in standing position). If the can is held at an angle / sidewards / downwards - then the spray will be with very little pressure / almost like it wont come out only (i suppose this is normal)
