Ha, yes the first thing I did when he went back into his crate voluntarily this morning was check out those gums, they are wet and carnation pink. I offered him water and he drank. It's not hot here...yet. Supposed to be up to 90 here in upstate NY but we have 2 air conditioners and the house stays below 76 on days like these. I also have a fan in front of their crates circulating air. Just took his temp again (3x) and it's dropped an entire degree. Now it's 103.1. I called the vet and rescheduled the appt for another 2 hours from now to see if it drops further. He gets VERY carsick and I don't want to stress him out further if his temp will go down on its own. In the meantime I've got both AC units running and a bowl of cold water in his crate with a few ice cubes in it. Crossing my fingers eyes and toes that his temp drops another degree at least.
Honestly it would not make a hill of beans if he puked in the car.If he were mine,he would be at a vet ASAP!
A 104 temp is nothing to be messing with.Even with his short bursts of "acting normal". I say he needs vet care. It could be beginning signs of an array of issues.
I have had shelter pups here fine one hour,and come down so deathly ill within a short amount of time.At 15 weeks,it could be anything.From Cocsidia,to Giardia.To something worse even.
Don't be messing with it,get him there~
