Bright colors pop and get people’s attention. Add vibrant pinks, greens, or blues to the flyer so it stands out. For example, you could make the background of the flyer magenta or turquoise and add a vibrant-colored border around it. Contrasting colors are colors that are opposite on the color wheel. Colors that contrast make each other stand out, so incorporating them into your design can help people notice the flyer more easily. Some contrasting colors you could use are blue and orange, yellow and purple, and green and red. Try using only shades of blue or all reds. You don't have to use a lot of colors for the flyer to catch people's attention; people just want to look at something aesthetically pleasing. You can achieve that with one eye-catching color. A high-quality photo will get people's attention, just make sure it's relevant to the event. Avoid using photos that are blurry or low-quality. For example, if you're advertising an event at the beach, you could use a photo of a palm-tree-lined beach that has vibrant greens and blues.

One-sentence summary -- Use bold, vibrant colors in your design. Use contrasting colors to make the flyer pop. Stick to one color for a simpler flyer. Add a crisp, colorful photo to your design.


During the abdominal palpation, the vet feels the bitch's tummy for the presence of puppies. The earliest date that this is likely to be successful is at least 21 days after mating. At this early stage the vet is feeling for an enlarged, thickened womb rather than puppies (which are like small blobs of jelly at this point).  The best time for abdominal palpation is day 28. This is because the puppies are now big enough to make a "bump" in the womb, much like beads strung along a necklace. By day 35, the each puppy is surrounded by his own fluid capsule and the vet feels something akin to a fluid string of sausages. Bear in mind that at 28 days each puppy swelling is a maximum of 25 mm (1 inch) in diameter, making it difficult to differentiate embryos in a womb from food in the gut or feces in the bowel. Furthermore, if your dog is tense and braces her belly wall, it can be impossible to feel anything worthwhile–the equivalent of trying to see through a window that has been painted over. Likewise, a single puppy can easily be missed, or mistaken for another structure such as the bladder, a kidney, or even feces in the bowel. Don't feel too frustrated with the veterinarian when she suggests a pregnancy test, as the abdominal palpitation can be inconclusive. The blood tests looks for high levels of the pregnancy hormone, progesterone. To be reliable, this test should be done after day 28. Before this it's possible to get false positive results, because the high levels might be a result of delayed decay of the hormone present during ovulation. However, after day 28, high levels of progesterone confirm pregnancy. Ultrasound scans are a popular way of confirming pregnancy, because in the hands of a skilled operator small changes in the womb can be detected as early as 18 days. The other advantage is that the technician may be able to give you an idea of how many puppies are in the litter, which is useful to know when it comes to the birth, or whelping.  Placental units can be visible from day 18, and from day 28 the fetal heartbeats are visible.  Note that the ultrasound is a noninvasive procedure that is done while your dog is conscious. The ultrasound equipment sends a beam of high-frequency sound waves toward your dog's uterus, and the waves created "echoes" which are converted into images. This is considered a safe procedure. The fur on your dog's abdomen needs to be clipped so that the probe can make good contact with the skin. X-rays have largely been replaced by ultrasound for detecting pregnancy in dogs. Because they are only of use once the fetal skeleton is calcified, which happens after day 49, the diagnosis is made relatively late in the pregnancy. As for safety, while the risk of irradiating puppies in the womb is unlikely to do harm, it is likely your dog will need to be sedated, because current health and safety regulations for the operators of x-ray equipment mean they are not allowed to be in the room when the exposure is made. Since many bitches, especially when heavily pregnant, are not comfortable lying still and are likely to get up when left, the only other option is to sedate them. Sedating a pregnant bitch is best avoided because of the risk of a drop in blood pressure to puppies in the womb. For these reasons, the use of radiography for pregnancy diagnosis has gone out of vogue.

Hold the flag where you want it on the wall and push a tack through the grommets on the flag’s top corners. The grommets are the small metal rings used to fly the flag on a flagpole. If you’re hanging a large, heavy flag, use nails instead so it’s more secure. Run the rope through the 2 grommets on the flag and then tie the ends of the rope to 2 neighboring street lights or tall objects. Make sure the rope is tied high enough that the flag isn’t touching the ground. Mount the flagpole off the building so it makes a 90-degree angle with the side of the building. The flagpole needs to be parallel with the ground so the flag hangs vertically on it. Make sure the flagpole you use is long enough to keep the edge of the flag from brushing against the side of the building.
