Symptoms of foreign body absorption:
Attention - it can happen, that the dog vomits the object himself and eats it again!
WHAT has the beagle swallowed?
HOW much time has passed since then?
As long as the foreign body is in the stomach, you can bring the dog to the vet an he can induce vomiting with an injection and the dog will will possibly excrete the item.
But if it is about sharp or angular objects such as bone splinters, nails, sharp plastic parts, vomiting is not very clever, as it can also lead to injuries.
It also applies to large objects because they can get stuck in the esophagus during vomiting.
NEVER TRY TO MAKE YOUR DOG VOMITING WITH ANY HOUSEHOLD PRACTICE!
Therefore it is important if owe suspect the dog has swallowed something dangerous to go to the vet - they will probably take an x-ray or an ultrasound scan and decide if an injection to get the dog vomiting makes sense or they need to remove the object by endoscopic or surgical methods. These both require anesthetic.
If too much time has passed and the foreign body is already in the intestine, it may become entangled with the intestinal loops or get caught in a constriction and cause intestinal obstruction. In such a case, an operation will be necessary.
A good measure for smaller parts or until you get to the vet to give the dog sauerkraut. The cabbage fibers can envelop the sharp edges or tips. Therefore - there is always a pack of sauerkraut in our fridge.
