Once he realises he's going into the front examination rooms though, he's suddenly much less pleased with things and wants desperately to return to the Happy Land of smells (cat food!) and treats (not cat food). He's not that bad about it, but he's stubborn in his insistence of pointing and edging towards the door (open or not). He's still in relatively good spirits. Getting weighed... well, that's okay too, except he uses it as an excuse to get more attention (he doesn't pass up many of those). Then the realization dawns; it's time to go into the back examination room.
That's where Bad Things(tm) happen. Poking, and prodding and goopy stuff in ears, and neeedles! He's a good dog, but it . He's always glad I'm there; leaning and trembling some. Tempted by the opportunity to jump off the table (which would make a rather bad landing and possible real trouble for a dog of his age (13 now)), he leans more. Eye contact and he relaxes a bit.
Suddenly it's all over, and it's back to Happy Land. Tail going in circles, mugging the assistance for treats, back to sniffing the cat food, and the longer, leisurely stroll home (1.5km).
It was a tough day for him, and it's not even noon. Fortunately, his schedule for the rest of the day includes plenty of nap time.
