To say that organizations are some stray animal organizations, I think some individuals are better, but few. And the country, some irresponsible, nominally, but not. Therefore, if there is a well-known rescue center, send it; On the contrary, there is no rescue center nearby. If you have time, you can look after yourself.
Pay attention to hygiene when you do it yourself. I'm not sure what medicine to use. However, I found some useful measures on the Internet:
* Status: Bleeding.
* Treatment: First, confirm the location of the bleeding wound, and quickly press the wound with clean gauze, stop the bleeding for the pet first, and then quickly send the pet to the animal hospital for emergency treatment.
* Status: Pets bite, bite or tear each other.
* Treatment: First, carefully clean the wound surface with Youiodine, suck Youiodine with a syringe, inject it into the bitten part, deeply clean the wound to avoid bacterial infection, and send the dog to an animal hospital for treatment; However, in the case of ear laceration or tongue bite, because there are many blood vessels in these two parts, you should first press the bleeding wound with clean gauze on the way to the hospital to prevent bleeding.
PS: The saliva of pets can play a role in disinfection. Some pets can heal themselves through saliva, but care should also be taken to avoid wound decay.
I can only answer so much, I hope it will be useful to you.
