There will be a reason for her being afraid of the type of handling required for these procedures - it just may not be an obvious one unfortunately ;) More often than not it is either because no gradual getting used to such intimate handling has been done or when done was unintentionally carried out incorrectly (perhaps either too forcefully or too tentatively).
You don't say how old your dog is, what breed, or whether you have had her since the usual 8 week puppy stage - perhaps you could fill in the details as it may give some clue as to how best you can proceed now :)
I get youngsters used to handling as soon as we get them home (or my own litter from day one through to leaving for their new families). Have her on a loose lead, get someone else if possible to hold her lead and feed her
tiny pieces of something very tasty that she doesn't normally get (baked liver, kidney, heart for eg). When she is suitably engrossed in waiting for the next
really miniscule titbit, gently but firmly run your hand over the top of her head and continue the same pressure moving on to check her ears. Likewise, run your hand down her neck, onto her shoulder, onto her leg right to the bottom and check her feet individually. Again, run your hand down her back, over her croup and onto her tail finishing with checking her genetalia. For her mouth when stroking her head and muzzle mover to the lips and lift her front ones to check teeth - treat - check sides - treat - open jaws - treat. When she is comfortable with all that have a sliver of her baked treat on your finger and rub that inside her lips and along her teeth before letting her have it to eat.
All of the above will take time but will pay off with patience and consistency ;) I'd recommend doing it daily or even twice daily (say, before her meals) to speed the process which is ultimately to give her more confidence (and you too :) ) You may have to settle for only doing half her body in the morning and the other half in the evening as you don't of course want it to be at all stressful for her.
NB - IME the most important factor beyond patience here is that when carrying out the exercises in the beginning that the hand or hands stroking the dog
never loses contact with the dog during the process.
You may also find that a massaging technique called "Tellington Touch" will help in this process too - if you run a [search] here or use google you'll find lots of info on it.
HTH meantime, Teri :)
