Typical sea sickness remedies for humans work
on dogs. The 'standard' veterinary advice/dosage for the common remedies (dramamines, bonine, etc.) is up to 25mg/dog every 12 hours (but usually has to be 'hidden' in food, etc.) As equally important .... To relieve the 'anxiety' that accompanies mal-de-mar, valium @ 2-10mg/dog (dog size/wt. dependent) at 8-24 hrs. will take the "edge off'. Start with the minimum dose and work your way 'up' if needed but no more than 10mg.Just like humans, keeping the pet on deck, and 'stimulated' etc. will/may help plus gradual 'introduction' ... longer and longer trips until the dog gets its sea legs. I 'distract' my setter easily by "where are the ducks?' .... and she will scan the water for hours looking for ducks, etc. Her harness is arranged to attach to the same jackline that I use - keeps 'everyone' onboard. Of course, this is what I dose MY dog when needed but you should consult a 'knowedgeable' vet for concurrance/approval of the above. My vet 'bible'/source for onboard care for my dog is: "Wilderness Veterinary Companion for Cruisers and other outbackers" by David W. LaVigne ISBN 1-4116-6975-4 www.lulu.com/captdrdave
