RAVE : Took my yorkie to Dr. Overman , The Pet Doctor today. She discovered he has a heart murmur, for which she came me meds. He has a dislocated hind leg. That just showed up in the routine exam. She also told me he was allergic to fleas and the Frontline Plus was useless, hence the continuous scratching and hair loss. We got Trifexis. He tested negative for heartworms. Thank the Lord. She was very thorough and sweet as pie. I highly recommend her for your pets doctor .
