Take care of your dog!
To me, a dog is a good friend and should be treated as such. I have heard of many stories of people trying to discipline their dog and injuring it in the process. You never want to have that on your conscience.
I brought my shorthair pup to a barbeque to let him meet a lot of people and other dogs of every age. One of my friends saw my puppy and I noticed his face instantly changed. There was happiness in his face, but I noticed a tinge of sadness. I soon found out why. He shared with me that his dad had two shorthairs in the past. One froze to death because they kept it out in the cold without sufficient heat planning for their kennel. Another was a fantastic hunter that suffered another tragic death. My friend had taken the dog hunting. After shooting a couple of grouse, it was time to go home. He told the dog to hop up on the tailgate of the truck. When the dog whined, he kicked it in the butt. The dog jumped up on the truck, but didn'tŐt completely make the jump, striking his midsection on the tailgate. The next day the dog was dead. The dog had ruptured its spleen when it struck the tailgate. My friendŐs last interaction with the best hunting dog he ever had was kicking it in the butt. Can you imagine his sadness and regret?
Be careful with your dog. As tough as dogs can be, they can be injured by sometimes seemingly slight actions. Sometimes dogs need to be corrected. Find ways of doing so that will not injure them. Assert your dominance over the dog, but don't overdo it. (For more ideas and methods on how to do this, check out the "Dog Whisperer", aka Ceaser. You can buy some of his shows in Walmart. He has some of the best methods out there for asserting dominance with your dog and helping your dog become a well behaved, calm, submissive dog.)
I've spent a lot of time with dogs of many different breeds and ages. I've learned from dog training books, videos, and other people from novices and expert trainers alike. I still learn something almost every day. I've found that if a dog is over corrected incorrectly it can lose some of its confidence and become a less productive, less happy, and less trainable dog. Most dogs I have ever known look up to their owners with love and trust. DonŐt betray that. Also, don't forget that they are looking for a calm, strong leader. Make sure you provide that for them as well.
With that being said, I realize that some people are coming to this site looking for first aid information. I have health insurance for my dog, I recommend doing as well for others. Any time the dog is injured, I bring it to the vet. That being said, I have had to deal with injuries before I could get the dog to a vet. I recommend putting together a first aid kit with things like bandages, tape, iodine solution, liquid stitches, etc...
I'm including a site that I found helpful for a time when I had some questions on how to prep an injury. go to http://www.veterinarypartner.com/Content.plx?P=SRC&S=1&SourceID=20 - www.veterinarypartner.com
I know that sites change addresses from time to time. I found the site by using google and typing many different searches related to "vet first aid for dog". The exact phrasing of the search that brought me to the previous web page I do not remember, but that is the method I used to find it.
