Make sure to only click if the dog remains calm during these steps. If the dog reacts or shies away, it just means you went too fast. Simply go back to where you know the dog will be successful. This may be easier if you have a dog that always holds their tail high, but my dog's tail hangs pretty low when relaxed. Also, be sure to click while your hand is still touching the tail, otherwise they are being rewarded for you letting go of their tail.
I will then repeat these steps in the vets office, with my husband doing it, with the vet assistant doing it, etc. Obviously the thermometer will eventually have to be inserted, but I don't feel comfortable doing that on my own, so I will have to work with my vet.
The video below is of step 4 and 5. This is our 5th session of only a couple minutes.
