I gave Marley a bully stick and was keeping an eye on him as I worked and he chewed.  Within a matter of minutes (5-10 min.) the bully stick was gone!  It usually takes him a half an hour to get almost done, at which time I "trade" the remaining bully stick for a nummy bone.  I suspect that he may have swallowed the bully because I can't find it anywhere.  Will he digest this or should I be worried?  Do I need to contact my vet?

Thanks,

Thanks for the advice.  I will keep an eye on him to make sure everything is okay and that his bodily functions are working properly.
