The water should rest between your hairline and your eyebrows. Keep your neck and upper-back muscles relaxed while you swim. Your head should be cocked about 45 degrees forward. If you move your head down too much toward your chest, it will cause more resistance. You do not have to wear goggles to swim freestyle; however, when you have to close your eyes while you swim, it can make you anxious. And it will make it more difficult to concentrate on your stroke. When you wear goggles, it can help you stay balanced and oriented. You will know when to stop because you will be able to see the walls of the pool, and you won't have to worry about bumping into other swimmers. Adjust your strap, pulling the straps until the goggles fit on your face firmly and comfortably. Adjust the nose bridge. Pull on both sides of the strap if the nose bridge is a strap. The nose bridge fits properly if you press your goggles up to your eyes and they suction to your eyes without a problem. Fit the goggles to your head by putting the eye cups up to your eyes so that they suction to your face, and then with your thumbs, move the strap behind your head so that your goggles are firmly in place.

Add 15-20 drops of peppermint oil or peppermint extract to 1 cup (240mL) of water and put it in a spray bottle. Spritz it in the areas from where you want to repel rats, as they don't like the smell. You'll need to spray the area again from time to time; try to do it at least once a week. Peppermint may also deter spiders. Alternatively, dip cotton balls in peppermint oil and place them in the areas where you've seen rats. Rats dislike the smell of this leaf. Plus, if they try to chew on it, it may even be toxic enough to kill them. Sprinkle the whole, dried leaves around or even use fresh bay leaves if you grow the plant. However, keep in mind that this can also cause stomach issues in other pets, such as cats and dogs. Castor oil tends to keep rats away, as they don't like the scent. It's similar to how citronella works on mosquitos. Try making continuous lines of the oil where you don't want the rats to go, forming a sort of barrier. You may need to renew this when it rains if you're using it outside. Rats aren't fond of the scent of ammonia. Mix 1 tablespoon (15mL) of ammonia in 4 cups (0.95L) of water and spray it in the areas you've seen rats. Alternatively, try using glass cleaner that has ammonia in it. Never mix ammonia and bleach, as it creates toxic fumes.

Before you can properly dress a wound or scab, it should be dry. If your wound is oozing blood, place some sterile non-adhering gauze on it. If it soaks through the gauze, don't remove it. Removing it can restart bleeding by pulling off the healing tissue. Just place another layer of gauze on top. Keep the gauze in place until the wound stops oozing. Even if your wound has already started to scab over, it's important to keep it clean and moist. This helps it heal faster. Wash the site with soap and warm water, then rinse. Lightly pat it dry. While old ways assumed that keeping a scab dry helped it heal faster, modern research says keeping it moist is best. Slather a layer of petroleum jelly all over and around the scab after you have cleaned it. You can also use antibacterial ointment instead of petroleum jelly, but this isn't necessary for most wounds. Immediately after moistening the scab, cover it in a sterile non-adhesive bandage, such as gauze secured with tape. You can also use silicone gel sheets (look for these at a pharmacy), non-stick gauze wrap, or non-adhesive gauze under a wrap, especially if you're dealing with a big scab. While you're waiting for the scab to heal, take time to remove the bandage each day and clean the site. Moisten the scab again and cover it with a new bandage. The scab still won't disappear instantly, but this will definitely speed up the healing process.

If your dog was infected with either sarcoptic or cheyletiella mange, you will need to treat any dogs or other animals that your pet is in frequent contact with -- otherwise he could be re-infected. Talk to your vet about how to treat your other pets to avoid a recurrence of mange in your dog. If you suspect that a dog (or cat) in your neighborhood may have mange, you should keep your dog as far away from the animal as possible. Talk to the animal's owner to let them know that you think their pet has mange or call animal control if the animal is a stray. Following treatment, you should bring your dog back to the vet for periodic check-ups. The veterinarian can analyze skin scrapings to confirm that the mites have not returned. Do not attempt to treat a recurrence of mange without consulting your veterinarian first because some treatments can be toxic if used more than once in too short of a time period.
