Welcome! My name isXXXXX am a 2003 graduate from UC Davis, and currently a Medical Director of a veterinary hospital.

I am sorry to hear about this concern for Hudson.

The typical highest labeled dose to give a dog is about 0.4mg/kg body weight. So, let's say he is a solid 80 pounds. Well, that would be a dose of about 15mg. So, ~100mg is quite high. Excellent, that he is on fluid therapy support.

With overdose of amlodipine the vet must worry about very low blood pressure, very slow OR very high heart rates (it can be either).

Supportive treatment should include possibly some intravenous calicum, to counter the effects of a drug which is a calcium channel blocker! Definitely, ask the vet about giving intravenous calcium/

Also, if any slowing of heart or drop in blood pressure your vet could try to counter the effects with what are called beta-agonist drugs.

He should likely remain hospitalized and under 24 hour supervision for next 24 hours and maybe up to 48 hours.

I hope that information has been helpful.
