When the poop scavenger finds that the formerly lively and jumping dog suddenly loses its energy, walks with a limp, has weak limbs, and staggers when walking, don’t panic. As a poop scavenger with many years of experience, let’s talk to you today about why the dog’s legs are weak and weak, right?

1. Calcium deficiency

Puppies are in the period of growth and development, and their bodies need more nutrients. If the owner only feeds the puppy a single dog food for a long time, resulting in poor bone development of the dog, there will be calcium deficiency such as weakness in the hind legs and inability to stand. In this case, it is recommended that the owner feeds the puppy special calcium tablets or liquid calcium. At the same time, it is also necessary to feed the puppy scientifically and feed the puppy some calcium-rich foods, such as dried shrimps, kelp, etc.

2. Injury to the hind legs

If the puppy comes home from playing outside and its hind legs are weak and unable to stand, it may be injured, especially the dog that often shuttles in the grass. At this time, the owner should pay attention to check the dog's hind legs and paws to see if there are any foreign objects inserted or obvious wounds. If so, the foreign objects need to be removed in time, and then the wounds should be cleaned and disinfected. If it is more serious, it is recommended to take the dog to a pet hospital for treatment.

3. Arthritis

If the puppy has obvious pain reaction when touching its joints, it may be that the legs are weak and unable to stand due to arthritis. In addition, it can also cause systemic symptoms, such as listlessness, increased body temperature, loss of appetite, and even insomnia. It is recommended that the owner take the dog to the pet hospital for examination and treatment in time to reduce the dog's pain.
