My Rottie Boy is a good traveller but has no appetite for a few days after a long journey, so he has lost a fair bit of weight, he then regains some of the weight lost in the following few days, but the same thing is happening the next time, has anyone else experienced this problem? if so. how did you overcome it?

Only thing I can think of is to over feed him slightly for 3 or 4 days beforehand!
