I think it's thigh got punctured by fencing wire. It probably penetrated as deep as 1/2 inch. Surprisingly, I didn't see any blood on the wire, but I saw a small hole near it's thigh. When I look on the skin about 1/2inch from the hole, I can see that the area underneath and near the hole is red, while further from the wound, I can only see the color of the skin, which is pink, and some blood vessels. I have a broad spectrum antibiotic which contains amoxicillin trihydrate and tylosin tartrate. However, I am planning to use it 5 days from now since, infection usually occurs 2 to 5 days after having the wound. Should I use it earlier, or should I use it ONLY when I see signs of infection. What are the signs of infection on a puncture wound? The hole is about 1/8 inch in diameter. How long does it take before a new skin completely covers the hole? I already put betadine and triple antibiotic ointment around the hole( both inside and outside). I don't think any wire is stuck in there nor any other object other than dust and maybe dirt or poop( highly unlikely, since I didn't see any poop on the same kind of area(the area they stepped on) on the fence), and I saw a very small area with rush on the wire. I think the rush covers only about 4% of the total area of the wire that went through it's skin.
