Stick a small wooden board or popsicle on the dog's ear, then wrap it with adhesive tape, and give the dog calcium to harden its bones until it is tied to the ear and can stand up completely by itself after removing the adhesive tape. This process takes three to four months, but your dog is almost one year old and almost a dog. The chances may be slim, but we can try. Dobbin is always like this.

The auditory induction can reach1.2000 Hz, which is 6 times that of human beings. The farthest listening distance is about 400 times that of human beings. Dogs are also twice as able to distinguish the direction of sound as humans, and can distinguish 32 directions. It can be distinguished that the number of times the metronome vibrates per minute is 96 or 100, 133 or 144. For human passwords and simple languages, dogs can establish conditioned reflex according to the changes of tone and syllable.

Dogs can hear 40,000 cycles. The sound collected through the big ears vibrates the eardrum through the external auditory canal, even vibrates the ossicles of the middle ear, reaches the lymph of the inner ear, and then reaches the brain through the auditory nerve. Dogs can distinguish tiny or high-frequency sounds (ultrasonic waves). The ability to judge the sound source is also very strong.

When a dog hears a sound, it can see and hear all directions with its eyes because of the sympathetic action of its ears and eyes. At night, even if you sleep, you should be highly alert and can clearly distinguish the sounds within the range of 1 km. In particular, we don't need to yell at the dog. Too much sound or audio is a kind of adversity stimulus for it, which will make it feel pain, fear or panic.
