It's been 37 hours since dog ate bone...?

glad to hear she is feeling fine! Look. to be honest at this point i would say you are in the clear. i mean i would probably feel better at 48 hours but i think she is is eating and has been toileting properly she is her usual self then she obviously isnt having any problems and its unlikely in the next ten hours because she would be feeling sick already as the issues would have arrived either in her throat or digestive tract.
