Hello, my name isXXXXX and I have over 20 years of experience as a veterinarian.
I am sorry to hear that Abbey has possibly eaten a moth ball.
If it was the old fashioned type that contains Napthalene or you aren't sure and it has been less then 2 hours since she ate it then I would induce vomiting. She is a small dog and one can be enough to make her sick. Naphthalene toxicity can lead to anemia (low numbers of red blood cells), lethargy, vomiting, and sometimes damage to the kidneys or liver. There is no antidote to this toxin so getting rid of it is best. Once the damage is done we can only try and support them while they recover.
You can give her 1 tablespoon of 3% hydrogen peroxide per 15 pounds of body weight soaked up with bread (no more than 3 tablespoons even if she weighs more than 45 pounds).
Then take her outside and run her around to get the peroxide bubbling so she vomits.
If no vomiting in 10 minutes repeat the peroxide soaked bread dose once.
If you do not have peroxide then I recommend getting her to a veterinary clinic to induce vomiting.
If you do have peroxide and she vomits and seems to clear her stomach and be done I would check to see if the moth ball is present.
If it is present to try and settle her stomach today you can try either:
1) Pepcid-ac (famotidine) at one 10mg tablet per 20 to 40 pounds of body weight
every 12 hours.
2) Prilosec (omeprazole) at one 10mg tablet per 20 to 40 pounds of body weight
every 24 hours.
These will reduce stomach acid and should help settle her stomach.
I will have more recommendations for follow up care but I wanted you to have this to start.
