Why Chicken Broth needs caution
Plain, unsalted broth is genuinely useful, because it tempts a fussy or recovering dog to eat and drink. The problem is that almost every supermarket carton and stock cube contains onion powder and garlic powder, and those are alliums: they damage red blood cells and can cause anemia days later. Add a high sodium load, and the thing people reach for to help a sick dog can quietly make things worse.
What to look for on the carton
The useful version is a broth whose ingredients are water, chicken, and nothing else, or a home-made stock with no onion, garlic, or salt added. The versions to avoid list onion powder, garlic powder, dehydrated onion, natural flavoring, or simply spices, and often carry several hundred milligrams of sodium per serving. Low-sodium is not the same as allium-free, so both need checking separately.
Signs to watch for
From sodium, excessive thirst, vomiting, loose stool; from the allium content, later weakness, pale gums, dark urine, lethargy
What to do next
Read the ingredient list. If onion or garlic powder is on it, call your vet with the amount, and switch to plain unsalted broth or water going forward.

The remedy that can become the problem
Broth is recommended constantly for sick dogs, and the recommendation almost never mentions the ingredient list.
1. Hidden allium is the real risk here
Onion and garlic powder are among the most common ingredients in commercial stock, and dehydrated allium is considerably more potent by weight than the fresh bulb. A dog already unwell enough to be offered broth is the last dog that needs a red-cell insult, and because the anemia is delayed by days it will not be obvious that the broth caused it.

2. Better things to offer a dog that will not drink
If the goal is fluid and appetite rather than flavor, there are safer routes, and a dog that genuinely cannot keep fluids down needs a clinic rather than a kitchen fix. The beverage guide covers what is reasonable to offer and where the limits are. What can dogs drink besides water? →
FAQ
Plain unsalted broth has no toxic dose and a few tablespoons is a reasonable appetite prompt. Commercial broth with onion or garlic powder is the concern: a small splash once is usually low-risk for a big dog, but a bowlful, a repeated habit, or a small dog warrants a call, and allium effects can be delayed by several days.
Yes if it is plain and unsalted. If onion or garlic powder is in the ingredients, call rather than watch, because anemia develops out of sight.
Onion or garlic powder on the label plus a real volume, a small dog, an Akita or Shiba Inu, a dog with heart or kidney disease, or any pale gums, dark urine, or unusual tiredness afterwards.
