In one sentence, describe what the following article is about: One of the biggest problems with pine is that the tannins and resins inside of it often bleed through the paint. You end up with a brown ring, similar to a water stain. Shellac primers are very good at resisting color bleeding, although there are other types of primers you can use as well. Choose a stain-blocking primer that is compatible with the kind of paint you plan on using.  Shellac primers come in both spray and paint-on varieties and work with most types of paint. The spray-on version is faster for covering broad areas, but use the paint-on version for more consistency and detail work. Oil-based primers are much more resistant than water-based ones. You can pick one if you’re using an oil-based paint. Polyurethane and wax primers also work with oil-based paints. You may see different primer colors. White shellac is best for light paints, while gray is preferable for dark colors. Shellac primer is somewhat strong, so don’t use a foam brush. Dip your brush into the shellac to coat it, then tap it against the side of the can. Finish by applying the primer along the wood’s grain. Coat the entire wood in a thin but consistent layer.  Try using an inexpensive chip brush, which is a disposable type of brush with short bristles that hold up well against any type of primer. Save your better brushes for the paint. If you’re using a spray-on primer, hold the sprayer nozzle about 6 in (15 cm) from the pine. Sweep it along the pine at a slow but steady rate. If you’re working with knotty pine, consider priming the knots first for extra protection. Coat them 2 to 3 times, then apply 2 layers of primer across the entire piece like you normally would. Check the manufacturer's recommendations for a more specific estimate of the drying time required. It varies depending on the primer you are using. It also varies depending on the weather. Expect the primer to dry at a slower rate during cold or humid weather. To ensure the second layer of primer is consistent, wait for the first one to fully cure. The exact time it takes varies depending on the product. Apply the second layer just like you did with the first one. Keep it thin and consistent, working from one end of the wood to the other. Go along the grain at all times. Remember to let this layer dry fully as well before painting over it. Make sure the pine is well-coated before painting it. If the primer looks uneven, consider giving it at least 1 additional coating. Let each layer of primer dry before adding another one.
Summary: Choose a shellac-based primer to prevent color bleeding. Spread the primer over the pine with an inexpensive paint brush. Wait about 45 minutes for the shellac to dry. Cover the pine in a second layer of primer.

In one sentence, describe what the following article is about: Symptoms in pets can be nonspecific and vary greatly, and some pets won’t exhibit symptoms at all.  If your pet has been exposed to contaminated areas or other animals infected with leptospirosis, consider having it checked even if there are no symptoms. Younger animals are more vulnerable to serious long term damage to organs or even death.  Dogs seem to be more susceptible to becoming infected than other household pets. If you suspect your pet may have been exposed and you see any of the following symptoms, you should contact a veterinarian immediately.  Fever. Vomiting. Abdominal pain. Diarrhea. Refusal to eat. Severe weakness and depression. Stiffness. Severe muscle weakness. Getting your pet on antibiotics in the early stages of the infection is very important. Antibiotics will help your pet recover more quickly, lessen any damage to internal organs, and shorten the length of time during which you are at risk for infection. Because of the possibility of permanent damage to your pet’s health, as well as your risk of becoming infected through contact with your pet, ask your veterinarian for advice and information about what to do while the infection persists.  Typically, the infection will be active for between 5 to 14 days.  For some animals however, the infection can last for just a few days or for as long as several months. While your pet is infected, there is a risk of the infection spreading to you and anyone else caring for the pet. With normal daily activities like grooming, petting, walking and playing the risk for transmission is typically low. There is a risk for becoming infected through direct or indirect contact with urine, blood, or tissues. Also contact the veterinarian if your pet is experiencing problems due to symptoms from infection. Your pet may need dialysis and hydration therapy to recover.
Summary: Be alert to possible infection. Be aware of your pet’s level of risk. Talk to a veterinarian. Seek treatment if your pet is infected. Know what to expect. Contact a veterinarian if your pet is not making progress.

In one sentence, describe what the following article is about: Look for hooks, screws, vents, or knobs that are already in place and that could bear a few extra pounds. Note that this method will be most appropriate for lightweight pictures that aren’t in frames. Look for wall features that are out of the way and that could have a string run between them without posing a strangulation risk. Cut a length of string, twine, or wire that’s long enough to span the distance between the two wall fixtures, plus some extra for tying knots. Tie each end of the string to a separate wall fixture. You can either pull the string taut or leave it slightly loose and droopy.  A taut string will look more rigid and uniform, while a droopy string will look more relaxed and artistic. The choice between the two is a matter of aesthetic preference. Wire will be harder to tie than string or twine (it will be easier to wrap it tightly around your fixture than tie it), will provide an industrial look, and will allow pictures to slide around for quick re-positioning. Wire is thin and strong, but doesn't lend itself to the droopy look. Twine and string will be easy to tie, can be left droopy or pulled taut, and will provide a more rustic look.Twine will be thicker than wire or string, but stronger than string. String will be thinner than twine, but not as strong. Use clothespins or clips to affix your pictures to the string. If your string begins to sag more than it's supposed to or the knots won't stay tied, you may have too much weight. Either use stronger twine or wire, or tie a second string to different fixtures for a second row of pictures. To distribute weight and pictures evenly, place your first picture in the center of the string using your eye or a tape measure. Using the first picture as the center point that separates two halves, divide those halves in half again, and place one picture at each center point. Continue dividing your spaces in half and using the center points as picture locations until all your pictures are hung.
Summary:
Find existing wall fixtures. Tie on your string. Hang your pictures.
