Homeopathic remedy for Minna

I had been worrying about Minna's recurrent colds for couple months now, she already had several treatments of antibiotics from the vet so I started to look for homeopathic remedy for her...Minna has been taking one tablet of Respo-K four times daily for two weeks and she seems to get better; however, I am not sure if it has to do with the warm weather lately or Respo-K is working, I should write a follow-up after she finishes the bottle.
