Thank you,
While it is a drug rarely used in dogs, this is a safe dose for her size. So, we'd expect no serious adverse effects here. If anything, we could just see a bit of GI upset.
With that in mind, we have a few options here. If you wanted to err on the side of caution, you could induce vomiting and/or treat her with activated charcoal (just let me know if you wanted to discuss how to do this). But again since there is little risk of any issue, you can choose to just monitor her and offer some supportive care to reduce any GI upset should it arise.
To do so, you can consider offering a light diet option for a few days. Examples of an easily digestible diet include cooked white rice with boiled chicken, boiled white fish, scrambled egg, or meat baby food (as long as its free from garlic or onion powder). Ideally, we want to offer this as small frequent meals to keep her stomach settled.
Further to this, if she shows any nausea, we can also cover her with an antacid to keep her stomach settled. There are a number of antacids that are available over the counter and pet friendly. I would advise only treating with one, but the two I tend to use are :
*Pepcid (More Info/Dose @
*Zantac (More Info/Dose @
These are usually given 20 minutes before offering food (to allow absorption) and of course you want to double check with your vet if your wee one has a pre-existing condition or is on any medications you haven't mentioned.
Overall, Molly's tablet stealing will not cause any severe harm. Therefore, we can intervene but do not really need to. So, if anything we'd just want to use some stomach supportive care if we see any bit of GI upset for her.
I hope this information is helpful.
