My name is ***** ***** I am an experienced small animal veterinary surgeon, I will be very pleased to work with you today and will try my best to answer your question to your satisfaction.
I have prescribed surolan a great many times in my life and from time to time dogs ingested it. I can tell you that there is nothing in this product which will be toxic to your dog.
You may perhaps see a mild transient gastro-enteritis but probably not even that ...
There is nothing you need do in this sort of situation, your dog should be fine
I hope I have covered your question fully enough but if you would like further clarification or to talk things over a bit more then I will be on-line for the next hour or so and I will be more than pleased to continue working with you.Regards,Scott
