So, let's say you thought she had digestive issues or stomach upset...You could give Pepcid A.C. antacid. Same Pepcid we take. You could give a 1/2 tablet of a 10mg regular strength Pepcid.
Now, if it is more coughing, you could give some over-the-counter cough suppressant.
To ease coughing, you can give Dextromethorphan, which can be found over-the-counter. However, many cough medications over-the-counter are combination products. So, if you grab a product like Robitussin, make sure it doesn’t have other ingredients like acetaminophen or caffeine. If it also contains Guaifenesin that is okay.
The dose is 0.25 to 0.5 mg per pound of body weight every 8 hours.
So, a 20 pound dog could get anywhere from 5mg to 10mg of dextromethorphan.
If at anytime your pet is panting heavily for hours, has difficulty breathing or excessive coughing, regardless of the cause, please contact an ER veterinarian immediately.
Best answer I can offer for ways to help coughing or a way to help with stomach upset. Of course, NEITHER is a replacement for more immediate examination.
I hope that answer is more satisfactory?
