I haven't used any flea or tick meds. So I know nothing. I did take Chelsea in yesterday, again for her ears and for a flaky spot on her back and a sore under her chin and for the constant itching and chewing she does. He helped clean her ears out, gave me a salve to use in her ears and on her sores and she had a steroid shot, antibiotic shot and I got another demo and instructions on cleaning ears.
I love hearing how things are going in your play pen!!!
