It is not good for dogs to stand and walk because dogs do not have a spine to support standing walking. The healthiest way for them to walk is to walk on all fours. Standing and walking for a long time can cause problems such as patellar luxation, arthritis, and even spinal damage leading to paralysis. When a dog suffers from joint disease, the dog will be in great pain and needs long-term medication, otherwise it will affect the dog's normal walking.

Dangers of dogs walking upright:

1. Damage to the lumbar spine. The dog will put its entire body weight on its hind limbs. If this continues, the dog's lumbar spine will be severely damaged, and it may even directly lead to paralysis of the hind limbs.

2. Affect urination. After walking upright, the weight is distributed to the spine. Over time, the dog's medullary cavity will shrink, and the nerves will be compressed. It will be difficult to urinate, and the dog will not be able to control excretion on its own.

3. Damage to nerves. The head will inevitably be raised all the time. At this time, the central nervous system in the dog's brainstem will be damaged. Once damaged, it will easily cause the dog to have unstable breathing and even cardiac arrest.
