They might not allow you to come near the wound in order to treat it, even though it needs to be attended to. If your dog or cat is this way, don't let their temperament keep you from helping to care for their wound, even if they growl or bark or hiss at you.
Many people don't take their animals to the clinic for the simple reason that they believe that the injury will heal itself.
Often times when this is the mentality of the pet owner, the animal sustains long term injury because the wound, or broken bone has healed improperly, and no longer functions the way it once did. In order to fix it once that has happened, you may have to pay major money to have surgery done on the animal. So what does the person who can't afford to go to the vet do in order to properly care for their animals wounds? In the care of wounds, the two most important objectives are first to stop the bleeding, and then to prevent infection.
This is much the same as treating a human being. To stop the bleeding you simply need to apply pressure to the point of injury, but do not use a tourniquet as to prevent amputation. If a tourniquet is absolutely necessary, make sure to loosen it every twenty to thirty minutes to allow blood to flow to the limb. Otherwise, consider a tourniquet to always be a last resort.
First try to get something you can use to apply pressure with by pressing down on the wound.
Since wounds are painful to the dog, be prepared to restrain or muzzle before you treat the wound. A muzzle can be very cheap if you buy one at your local Petsmart or other pet store.
Keep one handy in case you ever need it. The last thing you would want to happen in the event that you do need to care for the wound of an animal that will bite, is to sustain an injury to yourself as well! You also may want to consider buying good animal healthcare insurance. Many new animal health care insurance providers are springing up around the country and you can possible find some car insurance companies to agree to pay for your animal health care in the event of a car accident too.
Don't overlook these services. Surgery and other animal health care issues can be very expensive if your animal is not covered. When treating a wound, it's always nice to be able to go to the vet/ animal clinic immediately knowing your pet will receive the proper care, and not having to worry about the cost!
