FYI folks......
The dangers of corn cobs if eaten in whole or part by our dogs.
Many dogs are scavengers, raiding rubbish bins for scraps but corn cobs, if swallowed whole or in part, are not digestible and cause a blockage in the intestine that can have tragic consequences. Please make sure you dispose of any corn cobs so that your dog cannot get to them under any circumstances. If treated in time the corn cob can be removed and part of the intestine taken out but this is a risky surgery with peritonitis a possible side effect and it is very, very costly. Death is a very real risk as a result of this happening.
If your dog shows any of the following signs or symptoms it is possible they may have an intestinal blockage which could be a corn cob or many other items that dogs find palatable that just don't pass easily through their system: vomiting or dry retching, diarrhoea (or straining), anorexia, painful abdomen, lethargy. Ring your vet immediately and they will be able to advise you on the best course of action, be it watch-and-wait or be examined immediately. Don't take any chances.
