While I have not been officially hired to care for pets in my past, for 9 years of my life I have owned a 210-pound Great Dane, a 50 pound (very active) cockapoo, and 5 cats. I would say I gained most of my experience caring for pets with my great dane, as he surely was a handful. He had quite a few health problems, so I am fully capable of giving dogs pills as well as liquid medicine, eye drops, and ear drops. I also have no problem keeping dogs maintained on a leash despite there size and love caring for active and playful pups.
