At What Age Do German Shepherd Ears Stand Up Straight? When your puppy is finished teething (around week 20), his ears should start to stick up or should be all the way up.

The Mayo Clinic warns that people who drink more than four cups of coffee a day may feel a range of side effects, including insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. How sensitive you are to caffeine depends on a number of factors.
Coffee containing caffeine can cause insomnia, nervousness and restlessness, stomach upset, nausea and vomiting, increased heart and breathing rate, and other side effects. Consuming large amounts of coffee might also cause headache, anxiety, agitation, ringing in the ears, and irregular heartbeats. Drinking unfiltered coffee can increase total cholesterol, low-density lipoprotein (LDL), and levels of another type of blood fat called triglycerides. This might increase the risk of developing heart disease.
