The reason why a dog’s ears are upright and the other is lying down may be caused by genetic reasons, or it may be caused by underdevelopment of the dog’s ears or calcium deficiency. First of all, if your dog’s ears are always upright and flat, it may be due to genetic reasons. Secondly, if the dog is originally a prick-eared dog, this phenomenon may be caused by congenital ear dysplasia, and the dog needs to be taken to a pet hospital for ear pricking surgery. Finally, if the dog’s two ears were originally upright, but now one is upright and the other is lying down, it may be caused by calcium deficiency, and the dog needs to be supplemented with calcium in time.

1. Genetic reasons

If the dog’s ears have always been one erect and the other lying down, or originally both ears were lying down, but now one of the ears is erect, it may be genetic. Caused by. Because one parent has erect ears and the other does not, it will cause the dog to have one ear upright and the other ear down.

2. Ear dysplasia

If the dog is originally a prick-eared dog, one ear standing up and one lying down may also be caused by congenital ear dysplasia. If the owner wants to restore the dog's lying ears to normal, he can take the dog to a pet hospital for ear pricking surgery. It is recommended that the surgery be performed when the dog is about 3-5 months old, so that the recovery speed is faster and it will not cause too much damage.

3. Calcium deficiency

If the dog’s original two ears were upright, but now one is upright and the other is lying down, it may be Caused by calcium deficiency in dogs. When dogs are deficient in calcium, it can cause skeletal dysplasia, so it will also affect the development of ear cartilage. For this reason, owners need to supplement their dogs with calcium in a timely manner to help them erect their ears as soon as possible, and pay attention to scientific feeding to ensure a balanced diet for their dogs. In addition, if the dog is in a state of calcium deficiency for a long time, it will seriously affect bone development, resulting in short body size, O-shaped legs, etc.
