In one sentence, describe what the following article is about: While we're not able to do much with our own ears, a dog's ears can be incredibly expressive. Be aware that dogs whose ears were clipped as a puppy may not have the full range of motion to express themselves through their ears. A dog whose ears are pricked forward or straight up is fully engaged in play, hunting, or concentration. This ear position can also indicate curiosity and can express the intent to do something, as the dog is turning to catch sounds. It is an obvious ear position in the early stage of a chase. A dog's ears being flattened, sitting against the dog's head, indicates that the dog feels afraid or threatened. Ears that are forward but close to the head can also indicate aggression. A dog's ears part way back but not flattened may be feeling unhappiness, anxiety, or uncertainty. A dog's eyes express as much as human eyes do, and just as you learn to interpret people's eye signals, you can also learn to interpret your dog's. Here are some of the more common eye signals: Eyes wide open: this means that your dog is feeling alert, playful, and ready. Staring: staring indicates dominant, challenging behavior. Avoiding eye contact: a dog trying to look away from your face can be showing politeness, deference, or submission. Blinking or winking: these indicate that your dog is being playful. Narrowed eyes: this can indicate that your dog is feeling aggressive and is preparing to attack. This gesture may be accompanied by staring. Dogs often show how they are feeling with facial expressions. Understanding facial expressions can help you interpret your dog's feelings and communicate with your canine companion. Smiling: believe it or not, dogs can smile. While it can be difficult to differentiate a smile from a snarl, checking other body language for signs of play or aggression can help you determine whether your dog is happy or feeling aggressive. If everything else adds up to a happy dog, then your dog is smiling, and this means it's happy and relaxed. Yawning: the meaning of a dog's yawning is dependent on the context, just as it is with humans (humans yawn because we're tired, need more oxygen, we're feeling stressed or embarrassed, or we notice someone else yawning). For dogs, yawning appears to be contagious just as it is with humans. Indeed, if you yawn in front of your dog, it may interpret it either as you being stressed (in which case, it will likely turn away from you to give you some space), or it will respond in kind and yawn too. Dogs also yawn as a way to ease tension, to show confusion or when they feel slightly threatened especially when meeting new situations or new dogs or animals. Mouth position: a dog that has its mouth stretched back, closed or just slightly open, is showing that it is very stressed, in fear, or in pain. This may be accompanied by rapid panting. If its mouth is stretched back and open, it is a neutral or submissive sign. A dog that is alert and content will have its mouth closed or slightly open, with the teeth covered. Lip licking: if your dog licks its lips in combination with a yawn, this can be a clear indication that it is feeling stressed, under pressure, or facing a threat. It's a commonplace gesture shown by puppies around adults, but the behavior should not continue into adulthood. In mature dogs, licking can also be part of the dog's sexual behavior as it finds chemical signals on grass, carpet, and the genitals of other dogs. A dog that is licking another dog's lips is showing deferring behavior. Bared teeth: a dog whose lips are curled out and his teeth bared is signaling aggression and an intention to use the teeth for biting. This doesn't mean that every flash of teeth means aggression though, and you must take care to note the other elements. If the teeth are bared and there is no wrinkling of the muzzle, this is a warning and a sign of dominance and territorial defensiveness. If the lips are curled, the teeth are bared, the muzzle is wrinkled, and the dog is snarling, this indicates that the dog is angry and ready to fight, and there is every chance that it will bite.
Summary: Understand your dog's ear position. Interpret your dog's eye signals. Watch your dog's face.

In one sentence, describe what the following article is about: The things you say to the guy, or even the things you talk about when you're not around the guy, can be a big indication of whether or not you have a crush on the guy. Here's how to know if the things you say mean that you have a serious crush: If you find yourself always teasing the guy. If you always end up poking fun at the guy without meaning to, it means you have a crush. If you talk really fast or stutter when you say anything to the guy, it means you have a crush. If you're careful about not saying anything that might make you look like a ditz or dumb in front of the guy, then you have a crush. And if you feel like everything you say to him does make you sound like a ditz, then you probably have a crush. If you can't talk to one of your friends for more than ten minutes without mentioning the guy, then you have a crush. If you have a crush, your friends may be able to pick up on it before you do. You can learn a lot about whether or not you have a crush on the guy based on how you act around him, or even how you act when he's miles away. Here are a few ways to know if your actions mean you've been bitten by the crush bug: If you go out of your way to hang out with him, then you have a crush on him. If you've never watched baseball in your life but are suddenly going to all the school games because you know he'll be sitting in the bleachers, then you have a crush. If you want to be near him whenever you do hang out. If you find yourself drifting toward him when you're in a group of friends, or even touching him in a playful way whenever you can, then you have a crush. If you can't stand being around him when he's flirting with other girls, then you have a crush. If your heart falls when you show up to a place where you thought he'd be and he isn't there, then you have a crush. It may not be a coincidence that you're suddenly spending twice as much time in front of the mirror whenever you know you'll see the guy. Here's how to know if your grooming habits and attention to your looks say that you have a crush on the guy: If you try twice as hard to look good if you know you'll see him. If you wear your best outfit, best hairdo, and most amazing eye makeup when you know he'll be there, then you have a crush. If you find yourself experimenting with new makeup looks or jewelry to see if he notices, then you have a crush. If you find yourself not caring at all about how you look if you go somewhere where you know you won't see him, then you have a crush. Let's say this guy is the athletic, typical-boy type. You might find yourself practicing basketball and soccer, or buying Nike shoes, so your guy can get interested in you. And if you want your guy to get interested in you, that basically means you have a crush on him and will kind of do anything for him.
Summary:
Be aware of what you say. Notice your actions. Consider whether you are starting to pay more attention to your looks. Be aware of changes to your personality.
