How to judge whether a dog can stand his ears? You can observe dogs' ears to see if they have the ability to stand up, or try to put something on their ears to see if they will stand up on their own.
To determine that a dog can have a straight ear depends on the breed of the dog. For example, the Corgi, Doberman and other breeds are the straight ear breeds. Labrador and golden retrievers are varieties with drooping ears.
The dog with a standing ear will stand up for about two or three months, and may droop and stand up again in the next time. Just observe the ears at the age of dogs and you can judge whether the ears will stand up.
You can also see whether the dog's parents have ears. If both parents have ears, then the dog is mostly ears, and it is unlikely that the dog will have ears with ears that will be born. When standing the ears, they need to be supplemented with nutrition, such as calcium tablets.
