Pets on Holiday - Embedded or Swallowed Fish Hooks

Pets on Holiday - Embedded or Swallowed Fish Hooks
Dogs and cats with embedded or swallowed fish hooks are another problem we see quite a bit of at our Raglan clinic. Usually these animals belong to people who are enjoying some recreational fishing while on holiday, but sometimes dogs will pick up old hooks when exploring beach or wharf areas, particularly at low tide.

What to do when hooks are embedded in the tissues of the mouth or skin:
Check to see whether it is buried deeper than the barb. If not, the hook should pull out easily, but if the barb is embedded then generally a trip to the local vet is required.

What does the vet do?
In most of these cases the animal is administered a short-acting general anaesthetic, the barb is pushed through the tissue (rather than pulled back), the hook is cut in half and removed. Sometimes antibiotics are required.

What to do when if a hook is swallowed:
If your dog swallows a fish hook and there is a length of trace leading from your dog’s mouth do not try to pull the hook out. You will only increase the likelihood of further damage.

Cut the trace and tie the end loosely onto the dogs collar. Although your dog may bite through the trace before you get to the vet generally this is not of consequence.

At the clinic we will examine the dog’s mouth to ensure that the hook is not lodged in the back of the throat, then take x-rays to determine the location of the hook. Usually it is sitting within the stomach, which leaves two possible courses of action:

1) Surgery to open the stomach and remove the hook; or

2) Wait to see if the hook moves through the gastrointestinal system and is passed out in the faeces. If this latter option is chosen the dog will need a course of antibiotics. We feed dogs several small wads of cotton wool hidden within some mince or dog roll. The cotton wool tends to wrap around the hook in the stomach and thereby reduces the chance of the barb catching in the lining of the gut as the hook passes through. You need to monitor the faeces until the hook is recovered. If the dog shows any behaviour that is out of the ordinary, particularly gastrointestinal signs such as reduced/lost appetite or vomiting, contact the vet immediately.

The chance of a hook passing through the gut without incident depends on a number of factors, including the size of the hook in relation to the dog, the length and type of trace attached, and whether there are any other hooks or tackle attached to the same length of trace. In my experience, most single hooks attached to a length of nylon trace in dogs larger than a fox terrier will pass through the gut without any complications, generally within 24-48 hours of being swallowed. For this reason, and because the surgical option is costly and not entirely without risk, most of the cases we see are dealt with conservatively, but the risk factors for each individual case must be weighed up. For example, if a hook has become lodged in the gut wall and appropriate action is not taken, then the consequences are likely to be fatal.Therefore, any dog that has swallowed a fish hook should be assessed by a vet with minimal delay.
