Two things may possibly happen.
1. Pain, as a result of contusion, which may later seen or progress as a bruise on the point of impact. Pain can be relative to your dog hence, a prompt monitoring is important. If the pain is prolonged (chronic) causing alterations on your pet's normal activity, a veterinary medical intervention is highly required.
2. Head injuries that need a constant monitoring to your pet. Incoordination of gait (walking), and other neurological signs (example, head tilting while walking, uncoordinated gait, and other related signs (including vomiting)) need to be referred immediately to your veterinarian for appropriate treatment. If these signs are not shown prior to the accidental head slip and shows afterwards, a veterinary medical assessment is highly required to check the extent of such injury.
Hence, for the time being, we suggest to monitor first your dog for these signs. Refer promptly to your veterinarian if signs persist.
