Paw pods are great tools to improve joint alignment, strengthening joints, ligaments, tendons and muscles, while improving core stability and balance.
Ask your dog to stand on the paw pod, this may take awhile to habituate your dog these, and trusting their balance while standing on them, so it may take awhile but be patient and reward every effort and allow lots of breaks where required.
Once your dog is confidently on the pod, ask them to hold the position and release.
