My puppy got adult Simparica Trio, adult dog got puppy dose. Help!

Updated On September 23rd, 2025

Pet's info: Dog | Goldendoodle | Female | unspayed | 7 months and 19 days old | 11 lbs

So I have a puppy and an adult dog I gave the puppy (6/7 months) the adult simparica trio drug and the adult one the Puppy one without realizing it. My mom had them out of cases and I thought they were the same it was the 11ib one and the 22-44 pound one. Will the puppy be ok? and what should I do for the older dog? Should I give her another dose?

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. You should monitor Purl for symptoms of vomiting, lethargy, lack of appetite, tremors, problems with balance. If you notice any of these signs, you should get your puppy checked by your local vets right away. According to the manufacturer's data the symptoms are NOT likely to develop after ingesting this dose. You should give your bigger dog another tablet to get the right dose for 22-44 pound weight (that should be 24mg of sarolaner, moxidectinum 0.48mg and pyrantelum 100mg).
