ok this is the run down, my dog ate a whole drum... swallowed it whole. acted constipated gave him 2 sticks of butter like the vet said and it went away 2 day later it came back. got an X ray he had a laceration, got pills for him. bought a grinder from northern tools (which leaves shards of sharp bones) he threw up the bigest pile of puke ive ever seen this morning. he just went poop... acted constipated, i checked the poop and it had bones that were rock hard. i am at my wits frigin end with this dog if its not one thing its another
