Human: How do I know if my dog has a concussion? Assistant: 
If your dog has a concussion, they may have difficulty walking or moving around. They may also be more likely to bump into things and not respond right away. You can check for these signs of a concussion in your dog by watching them carefully for changes in behavior such as being dazed or confused, acting unusually slow, having trouble standing up or staying balanced, or showing signs of disorientation or confusion.
