This drug can be safe for use in dogs if doses properly. Unfortunately your dog received a large dose and may suffer some side effect such as vomiting, diarrhea, sedation, agitation, hyperactivity, hyperthermia, disorientation, anxiety, aggression, ataxia, respiratory depression, coma, and seizures. I would watch Bella very closely today. If she begins to exhibit any of the above mentioned symptoms you will need to take her to the vet for supportive care. I hope this helps and that Bella will be ok. Let us know if you have any additional questions. Thanks for using Petco Pet Education Center, formerly Petcoach.
