Bowel obstructions are not to be dismissed as a small problem. This is mainly because most dogs won’t handle more than 5 days without eating. If your dog shows clear signs of obstructions (see above for symptoms), then you most likely need to solve it right away. The dangers are many, including the bursting of the intestines, internal tissue damage, and severe complications that could be life-threatening. Regardless of how far your dog could resist an obstruction, it’s better not to test it out. Call your vet right away and ask for immediate help if possible (especially if symptoms are apparent).
