1) Call your Vet or an After Hours Emergency Vet.

2) If the Vet agrees...
Feed the Pup several slices of white BREAD...
Local ER offers that suggestion when dogs eat bones.
The Bread helps to "pad" the bone ends.

Also, if Fido CHEWED the bones well;
there is not much danger of internal injuries.
Dogs that DON'T chew the bones and just bolt them down -
are more at risk.

And be sure to *INSPECT* all "output" from Fido...
*Watch* for the bones to pass through his system,
AND observe any Blood in the stool.
