Make a list & make sure he checks it all Think Head 2 Toe
1 Ears -for redness, mites, etc
2 Eyes
3 Teeth
4 Trachea- collapsed
5 Skin/coat
6 mammary gland-breasts
7 knees- signs of crippling
8 Clean Anal Glands-ewww
Take a fresh stool sample w/you, you can also bring your other pets samples (label bags by name) even though he isnt being seen to be safe no one has parasites- if any parasites are found, know your other pets weights to get meds for them then & avoid another office visit fee, get second round for to use in 7days for any hatched larvae then a few days later you can just take stool samples in for testing to be sure its gone-no office visit cost
If vaccinations/rabies will be due very soon, go ahead & get them so you avoid another office visit fee-I hate that making 4 trips for the same problem because they know you have to worm twice in a row to kill hatched larvae, so you will be back & then you want to come back to test & make sure its gone so $30 tacked on each time, its crazy, you wont have anything left for bling bling

Dont be afraid to speak up if he forgets something.
