Young dogs are notorious for this sort of thing, so you are not alone! Luckily for Lemmy topical antibiotics such as Fucidic acid are not particularly toxic to our dogs. The main side effect we see is mild stomach upset (runny poo, a vomit or two). Due to this, it is advised that Lemmy be fed a bland diet of boiled chicken and rice little and often for the next 24 hours. Do not offer any treats or dog food, which may be too rich. Monitor him closely and ensure he is drinking some water too.
Did he eat the tube itself? If so, this is slightly more of a concern. If he has chewed it well, it will likely pass through. However, there is a small risk that if he has swallowed a large piece of un-chewed tubing, there may be a blockage. Signs of a blockage can take a day or two to appear and would include lethargy, reduced appetite, bloated stomach, vomiting, constipation etc. While it is a small risk, we should still be watching closely for this.
In summary, he should be just fine with a bland diet but we need to keep an eye on him for the next couple of days.
