Hello
You should always call your vet for specific medication concerns. But in general this one time accident will probably not cause an issue. Please remember that medication overdoses are best handled immediately after they happen. In some cases we will recommend inducing vomiting.
Hello,
I always encourage my clients to be proactive and not worry versus sit back and wait. Is there a way you can call your vet to ask them if the incision needs to be looked at in person.? At our clinic clinic we often encourage emailing a photo before we decide whether it needs to be brought in to be seen.
