Hi there,

Thank you for your question and I'm sorry to hear about Chelsea. What are the symptoms she has that makes you think she could be nauseous? What was the flea/tick medication you gave her? Has she had any vomiting or other symptoms?

I will wait to hear from you,

Hi again,

Thank you for your patience. It certainly sounds like Chelsea is nauseous as you say, and this could be from the Simparica, however we also have to consider whether there is some gastroenteritis on the way here, a toxicity, or even an internal organ issue. The chances are of course, that this is just a little stomach upset from the Simparica, so don't be too alarmed. As she is likely quite nauseous right now, you may also want to try her with a little pepcid. The typical dose for this type of situation is 0.25mg per pound of body weight up to twice daily. You can read more about the use of Pepcid in dogs online here:

For now, make sure Chelsea has plenty of fresh water and encourage her to have a good drink if you can. Now and overnight, please keep an eye on Chelsea's mucus membranes, capillary refill time and respiratory rate tonight as follows (do be careful that your girl doesn't try to bite you):

Mucus membranes - flip her lip and look at the color of her gums. They should maintain a nice salmon pink color. Get her to the emergency Vet if they appear white or very pale pink, or if they are a dark deep red color.

Capillary Refill time - this measures blood perfusion and test this by putting your thumb on her gum to apply pressure. After you release your thumb you will see the gum blanch. Capillary refill time is the amount of time it takes (in seconds) for the gum to return to a healthy pink color from the blanched white color. If 2 seconds or less don't worry - if it is taking significantly more time, again - off to the emergency Vet.

Respiratory Rate - if she seems to be panting or breathing rapidly throughout the night, this is a sign of shock and or pain and a signal for a trip to the emergency Vet.

Please let me know if you have any additional questions I can assist with or clarify?

Many thanks and please give a pat from me, won't you :-)

Can I give my dog sodium citrate dehydrate
Customer: replied 16 days ago.
Expert:  Pet Doc replied 16 days ago.

No - this doesn't have the same anti-nausea effect as it does in humans and isn't used for this purpose in dogs.
