87 lbs 12 Year Old Dog Galloping In His Sleep

2am. Dog lying beside me starts having the wildest run in his sleep I have ever seen. He is galloping like a horse! I started recording while sitting. Tried to get up quietly so as not to wake him. Noises you hear is chair cushion squeaking. Dog has three fat lumps - one on chest, under front right leg and next to groin. Thank you for watching!
