If you've got a hardwood floor, you can obviously skip this step and go straight to finding the joists. If you've got a squeaky and carpeted floor, however, you've got to make the decision to either cut a small strip of it up to install under, or use screws that can be used through carpeting.  Some kits (Squeak-No-More) are available to use over and through carpeting, without having to remove it and risk damage. The process will be essentially the same, whether you pull up the carpet or not. If you must remove carpeting, pull it up near the squeak and keep it as clean and secure as possible so you can reattach it later with carpet adhesive. If you can pull up a particular segment of carpet along a seam, keeping it secure, that would be the best way of pulling it up, rather than just cutting a segment out from the middle. There's no easy way to cover up your work, and it might always show, unless you work along a natural seam. Walk in the squeaky area until you can find your squeaky spot for certain. Then, try to find the closest joist to the squeak using a stud-finder.  If you don't have a stud finder, you can use a hammer or another heavy object to tap on the floor and listen. The joists will sound flatter and thinner when you tap on it, while the other side will sound deeper. To be extra-sure, you can drill a pilot hole using a depth-control bit in your variable speed drill to make sure that you're hitting the joist before you use a screw and come up short. Drill through the squeaky boards, the subfloor, and attach both to the joist to securely fix the squeaky board. To do this, you'll need heavy-duty wood screws of the appropriate length. You can get some sense of that length when you drill your pilot hole. Some kits will come with break-away screws that you can use to make the repair almost undetectable, especially through carpet. This is a very effective way of securing your boards cleanly and efficiently. If you're working on a hardwood floor, it's important to keep the spot looking as clean and smooth as possible. Wood putty, also known as plastic wood in some places, is a type of putty made of sawdust and some type of binder, and is very effective at filling the holes left around the nails. It's available at most home repair stores for a few dollars. Apply a small amount and sand the area smooth. You can match the tone of most wood putty to the wood tone of the floor. try to get it as close as possible. If you're carpeting back over it, don't worry about using wood putty. In some cases, it might be a good idea to smooth back over the top of the screw that you installed to smooth things out. If your floor is carefully stained, this would be a bad idea, but you might need to smooth out the wood shards from the screwing job, or smooth out the rough edges of the wood putty you installed. Use extremely fine grain sandpaper, and don't overdo it.

One-sentence summary -- Remove the carpet over the squeaky area, if necessary. Locate the joist nearest the squeak. Fix the loose board to the joist. Fill the hole with wood putty. Sand the spot.

Article: You want to find natural foods for your pet that are created from real meat, vegetables, grains, vitamins, and minerals rather than just a variety of preservatives and chemicals. If you can read the ingredient list without a dictionary, chances are the food is healthy and nutritious. Look for labels that say the food is “fit for human consumption.” If you can’t eat your dog’s food safely, it is much more likely to harm your dog’s digestive system. Many advertisements tout meat as the first ingredient, but this doesn’t always mean that your pet will receive high quality protein. In some cases, this may not even mean your dog is receiving more meat. Ingredient lists on nutrition labels are ordered by the weight of each ingredient as it is added to the recipe. Once cooked, this weight can change, so these lists can be misleading. In order to select a pet food with the best quality, natural ingredient, you'll need to understand how to accurately read these ingredient lists.  Check for the percentages of protein, fat, and other nutrients in addition to reading the ingredient list. Different foods may offer the same amounts of key nutrients, but they can vary dramatically in price. This is generally because the more affordable foods use lower quality protein sources. Purchase the best quality food you can afford. This can include salt, sugar, artificial colors, and added flavoring. These unnatural nutrient sources do not add to your dog’s nutrition in any way, but they are designed to make the food last longer without spoiling, look more appealing, or taste more like foods that your pet enjoys. While some dogs never show signs of digestive or other health concerns caused by consuming these unnatural food additives, others show significant negative response like decreased energy and elevated risk for diseases common among their breed. This is especially important as your dog ages or for younger dogs who are less active. Many prepackaged pet foods, even natural ones, include large amounts of sugar that make the food very high in calories without increasing nutritional value. In order to feed your pup the right number of calories, you’ll have to feed them a less than satisfying amount of food. Ideally, your dog’s food should be between 300 and 350 calories per cup, but most store bought pet foods are between 400 and 500 calories (or more) per cup. Count calories to make sure you’re not overfeeding. Most major, commercial pet foods, canned, dry, or refrigerated, are manufactured months before they reach the store. This means they’re high in preservatives that can decrease the nutritional value. However, many pet stores offer natural foods prepared in smaller batches or by local pet food manufacturers that have a much shorter shelf life because they use fewer preservatives. You can also purchase these more naturally derived foods from online directly from the manufacturer. Talk to your veterinarian or local pet store to get recommendations for natural, preservative free, and locally sourced dog foods. If you want to naturally boost the nutrition of any type of dog food, include some nutritional extras with every meal. Canned meats like chicken and salmon can dramatically improve your pup’s protein and vitamin intake when mixed with store bought food. Another great, low fat treat that packs a heavy vitamin punch is canned pumpkin. Add a few scoops to your dog’s meal once or twice a week to boost digestive function and deliver a number of necessary vitamins and minerals.
