How long does it take for a Pomeranian’s ears to stand up?

Pomeranians usually start to raise their ears at 1-2 months of age, but the two ears generally do not stand at the same time and do not pop up all at once; they are usually fully erect by about 3 months. During this period, the owner can give the Pom more calcium – for example, a natural dog food higher in calcium – to help the ears stand sooner. If the body lacks calcium, ear-standing may be delayed or prolonged.
