Welcome to JustAnswer! I am a licensed veterinarian and would be glad to help!
How much does she weigh?
So I can best make a dose for your dog that is also convenient, what size (milligrams) pills do you have?
I have zantc 150mg tabs. I should also mention that she has also been having loose stools.
Based on your dog's weight you should give 1/8 of that tablet every 12 hours.
If that is not possible you can give 1/4 tablet once per day.
I hope this information helps!
