A tip for getting her in the car without being bitten.... use a crepe bandage as a muzzle..... put the bandage over her muzzle and tie it with one knot under her mouth, then bring the 2 ends up behind her ears and tie them in a bow.

Had to do this with a Jack Russell bitch we had once, when we took her to the vet, or tried to clip her nails.

How old is she?

Hope the pills work for her.
