If this were my dog I would at least call the Vet and see if they want to see the dog. Watch his poop. If you see blood or dark colored or coffee ground looking areas, find the money and get to the Vet. He has internal bleeding.

He could have anything from just superficial soreness to internal injury, to a bruised or even lacerated internal organ, like the liver. He could have internal bleeding, which can be very serious.Is his midsection looking at all bloated? That can be sign of serious internal bleeding.You don't have to go to an emergency vet first for this. Go to your regular vet. There are various blood/liver enzyme tests they can run to see what's up, Tell your vet what you can afford right now and he/she can concentrate on what tests he/she thinks is the priority.One of my dogs was recently hit by a car. We took him straight to our own vet. He had no serious visible injuries, so they looked to internal injury. One liver enzyme tested literally off the chart. They said it was indicative of abdominal trauma, anything from bruising to laceration.Turned out to be only bruising. Took the dog a full 7-10 days of laying low to fully recover. His appetite was off for several days.Cost of that particular liver enzyme test: $17. Not that you'd ask for just that test, but just an indication that this stuff isn't all godawful expensive.That said, the total cost for that vet visit, which included 3 xrays, an ultrasound and alot of bloodwork, was @ $600 .. but that was for soup-to-nuts complete triage of a dog going into shock from a car hit.PS - regarding the comment about cow milk. If your dog tolerates it, then no worries at all.
