Thank you.   Thanks everyone else too.
Thinking this over more (because I'm not normally an anxious person) I think this may be the problem.  My pug was 6 1/2 years old when she died.  Perfectly healthy and happy when we left and then about 3 days before the end of our 7 day vacation, I got the phone call.  I can't even begin to describe agony I went through.  Guilt, pain... agony.   
Now I have a wonderful pugapoo (poodle mama, pug daddy) who is one of the great loves of my life.  I just yesterday found out that he has a problem with his thyroid that has resulted in hypothyroidism.  His vet appointment was this past Friday, got the results yesterday, so he's only had 2 doses of his medication.  After he is on his meds for 4 weeks my vet is going to test his thyroid levels again to see if she needs to make any adjustments to his dosage.  Because of this he needs to be given his medication EXACTLY as directed.  If he had been on his meds for a while then maybe I wouldn't be feeling so anxious about this trip.  To top it off, something is going on with his eyesight.  His pupils aren't constricting like they should and his vision isn't right.  AND (maybe the clincher here) he is 6 1/2 years old. 
  
Anyway, thanks for letting me vent, it is helping me think things out.
