Yes, it's usually a part of a protocol for maintenance of canine lymphoma. It's dosed at 2.5 - 5 mg/m squared and so 5 mg for such a large dog represents a very small dose. How much does he weigh, please, so I can be more accurate for you?

125 lbs

Thank you. 125 lbs = 56.8 kg = 1.5 m squared. 2.5 - 5 mg/m squared x 1.5 m squared = 3.75 - 7.5 mg. I mispoke as 5 mg isn't a very small dose but, instead, a recommended dose for this drug. I would induce emesis by administering 45 mL (3 measuring tablespoons) of 3% hydrogen peroxide by means of a small poultry baster placed between his cheek teeth and cheek. He should vomit within 15 minutes. If not, please repeat the same dose. This is predicated upon his recently (within 90 minutes) ingesting it. Please keep me posted.
