Traps come in a variety of shapes, sizes, and configurations. A store that sells hunting equipment will likely have traps available for purchase. If you do not want to purchase a trap, consider calling your local animal shelter or animal control center to inquire about renting or borrowing a trap. When asking someone for help to obtain a trap, provide as much information as you can about the dog. This will help you select the appropriate trap size and configuration. The trap should be in an area where the stray dog frequents. Ideally, this area should be where the stray dog would be comfortable approaching without feeling threatened. In addition, you should place the trap where you could monitor to it without trespassing on personal property or being otherwise obtrusive. Set the trap on a firm, flat surface. It is important for the trap to be inviting to the stray dog. If he does not feel comfortable around it, he may approach it but not walk in it. For example, cover the trap with blanketsthis will help him feel safer when he steps inside of it. Also, place several layers of blankets on the bottom floor of the trap for increased comfort. If you set the trap directly on grass, place a sturdy waterproof barrier under the trap to keep water from getting in and soaking the blankets. A dog-catching expert could advise you on what type of barrier would be best. Place tasty food in the trap. Examples of good food include pizza, hot dogs, and various meats (e.g., boneless chicken, beef, liver). Hide the trap mechanism with blankets. The trap mechanism is like a hill. If the stray dog sees it, he will not step on it. With enough blanket cover, he would step on the mechanism and not even realize it, thus securely trapping him within. Clear away any objects (e.g., rocks, pinecones, leaves) from the trap entrance that could prevent the door from closing. Set the trap out when the stray dog is most likely to start roaming: dusk, dawn, or midnight. Be sure the trap closes properly before leaving it for the stray dog. To test the trap, use your hands to apply pressure to the trap mechanism. If you have a dog that is a similar size as the stray, have him walk into the trap. If you think the stray dog is too small to set off the trap mechanism, place an extra weight (e.g., rock, brick) on the side of the mechanism. Check the trap the day after you have set it up for the stray dog. If you see him in it, contact your veterinarian, a local animal shelter, or your local animal control center for further instruction. If you are able, transport the stray (still within the trap) to your veterinarian, shelter, or animal control. If the stray is not in the trap when you check it, prepare the trap again for another day. Keeping your eye on it will be important to keep other animals from going inside the trap. If other animals are in there, the stray dog will likely not go near it.

Article: While rare, some modems encounter issues when paired with a specific Internet company (e.g., Comcast). Double-check your modem's compatibility with your current Internet subscription before buying (if possible). If you find that your modem won't work with your current subscription, try to exchange the modem for a different one that will work, or switch your Internet subscription. The cable output resembles a metal cylinder with a small hole in the middle and screw threads all around the sides. You'll usually find cable outputs in the wall near the floor in living rooms and bedrooms. In some cases, there will already be a cable connected to the cable outlet. The modem should be relatively high up (e.g., on top of a bookshelf), and it will need to be close enough to the cable output that you can connect it without stretching or bending the cable. You'll also need to have a power outlet nearby. A modem generally requires a coaxial cable to connect to the cable output, as well as a power cable to connect to an electrical outlet. Both of these cables should come with your modem, but if you bought it used, you may need to find replacement cables. If you plan on attaching the modem to a router, you will also need an Ethernet cable. Consider buying a longer coaxial cable if the one that you have is too short to allow you to mount properly your modem. Each modem is unique, and yours may require additional setup outside of this article's capacity. Reading your modem's manual will help make you aware of any additional steps that you have to take to install the modem.
