Puppy not too happy with me :(

Question
Hi, about 3 weeks ago I bought a puppy labrador (her name is lucy), it was
great at first, the puppy seemed very happy. But then I discovered she had
vaginitis, so the vet told me to administer antibiotics for 7 days. And for 7
days I had to force her mouth open and throw the pill on her throat, as she
would spit if I just left there or refuse to eat if mixed with food. But the
problem is that each time I forced her mouth open I also had to hold my knee
on her body onto a corner so she didn't move, but she cried every time I gave
her the pill. It broke my heart when I got near her little house and she ran
away crying, like she was scared of me. Her illness got better and I started to
bring her treats every time I went to see her, and her tail began to wag again
to my presence, but she runs directly to my hands and sniff it to see if i
brought food. When my brother or friends come see my dog, she seems way
happier and playful with them than to me, she also use to follow me
everywhere I went, now she prefers to follow my visitors and ignores me.
Is there anything I can do so that she'll treat me like when I first got her?

Answer
I sort of did that to Pepper.  I got her Sunday, and Wednesday the vet gave me eye and ear drops for the next 10 days.  What an abusive home.  Give her some more time and lots of belly rubs.  Try this:

''Elevation for small puppies: Sit on the floor and gently put your hands around your pup's middle, below his front legs, and lift him up. He is facing you. Hold him for 15 seconds. Repeat until he no longer struggles. If he is past 10-12 weeks, lift his front feet off the ground, but don't pick him up.

Cradling for small puppies: Hold your puppy gently on his back, as you would cradle a small baby. If he struggles, hold him firmly until he quiets for 10-15 seconds. With larger pups, you can do this as your sit on the floor, with your pup between your legs.

Quiet lying down: Place your pup on the floor on his side, with all 4 legs pointing away from you. Use your hands on his neck/shoulder area and middle, to hold him in this position. When he is quiet, praise him. Lengthen the time that you keep him quietly in this position. When he accepts this position well, handle his paws and muzzle, while keeping him quiet.''

The quotes mean this isn't my original work. It is copied from my Puppy Raising Manual. I have long used these or minor variations of them, and they are very effective. You may want to give him a belly rub while he is on his back too. Helps bonding. There is a big difference between him rolling over and demanding a belly rub, and you choosing a time to roll him over and rub his belly. The latter cements your place as pack leader.

Unfortunately, sooner or later you will be back to pills.  Try rolling them into a glob of peanut butter.  My 14 year old has cancer of the jaw and I can't shove pills in.  The peanut butter sticks to the pill, and the dog can't spit only it out.
