One important lesson to remember is that ANY dog will bite if he is frightened or fearful enough. Here's a quick, easy way to muzzle a dog in an emergency; you can use any number of items from around the house including a thin leash or rope, pantyhose leg, even a cord from a window blind. Have a pair of scissors on hand so you can cut it away quickly in an emergency. Remember, a dog who is muzzled cannot pant to cool himself so watch for overheating, and never muzzle a dog who is at risk for vomiting as it puts him in danger of aspirating. However, if your dog is injured and you need to transport him to a vet, this video may just give you the information you need to enable you to get everyone there safely. It's also important to remember that if the dog is determined enough, he CAN bite you through the muzzle (especially if you are a novice at placing them), so NEVER trust the muzzle completely and keep your hands out of harm's way. It should give you the advantage in getting out of the way if the dog does decide to try and bite. Don't be afraid to tie the muzzle as tightly as you can- remember, this is generally going to be an emergency, we are worried about safety, not long term comfort, and if you didn't tie it considerably tighter than you probably were comfortable with, odds are the dog can get out of it. It won't be on long, a muzzle that's too loose is more dangerous than no muzzle at all as it gives you a false sense of security.
