Article in English: Porcupine quills are much less likely to cause lasting harm if they are removed from the animal within the first 24 hours. Animals that are treated during that period almost always make a full recovery. Delayed treatment, on the other hand, increases the chance of complications such as broken quill tips, eye or joint damage, and infection. Dogs that have quills in their mouth region may not be able to eat until they are removed.  Many veterinary hospitals accept after-hours patients for emergencies. If you cannot treat the animal immediately, try to keep it from pawing at or breaking the quills. Restrain it to minimize any movement if the quills are in its chest or abdomen, where breakage is most dangerous. Removing quills from an animal at home is a painful process, and even a gentle animal will struggle. If the animal is pierced with 10 or more quills, has quills embedded near the mouth or eyes, or has a tendency toward aggressive behavior, make an effort to find a veterinarian. Only attempt home removal in these situations as a last resort.  If quills are embedded in or around the eye, removing them yourself is dangerous. Broken quill tips in the eye may require medical equipment to locate and can cause serious damage.  If quills are embedded around the mouth, the animal may have quills embedded in the mouth or throat. These are difficult to locate and remove at home, and could interfere with your animal's ability to eat until removed by a veterinarian. Unless the animal is small and unusually calm, you should have a friend hold it in place. Choose someone the dog is comfortable with, if possible, to further minimize stress and struggling. Struggle during quill removal can cause the tips to break off and dig deeper into the animal, where you cannot reach them.  Do not muzzle the animal unless there are no quills in or around its face, as the muzzle could break quills or push them in further. Almost all dogs injured by quills have quills in this area, often in addition to other locations, so check...
