Hello, my name is***** and I have over 20 years of experience as a veterinarian. I am sorry to hear that your pups got into the Dis-taste chews and ingested about 20 of them about 12 hours ago.
I am pleased to hear that everyone seems to feel fine.
I am assuming you aren't sure which dog ingested how many, or if one may have eaten them all?
Of course the concern is salt toxicity, as 20 chews is 12,800mgs or 12.8grams of salt. A lethal dose is dogs is about 4 grams per kilogram (2.2 pounds of body weight).
Your smallest dog is 30 pounds or 13.63kgs. A lethal dose for her would be 54.55grams. So even if she ate them all it would not be a lethal amount of salt. But she could have other symptoms of toxicity.
Excess salt intake in dogs results in vomiting within several hours of ingestion, then signs can progress to weakness, diarrhea, muscle tremors, and seizures.
Since your pups seem fine 12 hours later, with no vomiting or diarrhea which should be the initial signs, it is unlikely any one dog ingested a toxic amount, but it is worth keeping a close eye on them for the next 24-48 hours.
There is no specific treatment for salt toxicity, and I suspect that they have been drinking enough to wash out the excess sodium and keep their blood levels within an acceptable range. But if they develop symptoms then have them seen by a veterinarian and placed on intravenous fluids.
Please let me know if you have any further questions.
