My dog ate Zofran (Ondansetron). Is this dangerous? Should I go to ER?
Ondansetron (Zofran) can cause constipation and atrial fibrillation even at normal doses. A normal dose would be 0.5mg to 1mg/kg twice daily, so your dog clearly got an overdose. This may be detrimental, but possibly also not. You should take Cash to a Pet ER for inducing emesis (vomiting) or you can also call the pet poison line for advice: 24/7 Animal Poison Control Center 855-764-7661 $59 USD per incident fee applies

Does Petco provide pet prescriptions, or is it just for advice?
Unfortunately, we cannot (legally and ethically) advise medication without having an established patient-doctor relationship. It is also dangerous for us to advise medication without examining the animal and fully understanding their condition and medical history. The only place to get a prescription is through a veterinary clinic. However, some vets may be comfortable writing prescriptions for well-established clients that they trust know the conditions they are treating for. This service is strictly for advice only. I hope that helps and all is well with Onna.

Can I safely buy my dog's prescription eye medication online?
Hopefully it is the same medication, although there have been lawsuits about mislabeled and counterfeit medications with online pharmacies. Also, you do need a prescription from your veterinarian in order to purchase these products. I would recommend visiting with your veterinarian, as there is a possibility they may price match for you. Best of luck and thank you for using Pet Coach.

How do I prepare my sick small dog's vet-prescribed medicine?
Hi, thanks for using PetCoach! Unfortunately you didn't provide your dogs weight so we can not give you doses. I recommend calling your Vet when they re-open. In the US it is not legal to prescribe medications with out a label and the medications not reconstituted (made in to a liquid from the powder form). Are you in the US? Also in the US we do not prescribe Acetominophen ( https://www.petcoach.co/canigive/dog/tylenol/ ). I recommend calling your Vet regarding that medication as we can't recommend giving it to dogs. I am sorry but if you want to re-post with Ringa's weight we can probably help with the Amoxicillin).

My dog stopped vomiting. When can I stop giving her Zofran?
If it has been over 24 hours since Lola vomited I think I would give one more dose of zofran and then discontinue the medication. As long as she is eating normally and does not continue to vomit I don't think you have much to worry about. However, if the vomiting starts again you may want to restart the zofran and have Lola examined by an emergency veterinarian (especially with her history of PLN). I hope Lola continues to feel good and you have a good holiday weekend!
