I had my girl spayed last month and when they tested her for heartworm, part of the test also tests for lyme. Her lyme came back high so they wanted to do a specific lyme test to see if she needed to be treated for $75. I couldn't really afford the extra but did it. It came back positive so they gave her antibiotics (not sure why they couldn't just do it in the first place). So today I brought my australian shepherd in to get neutered and his also came back high so they wanted to do the same test. I told them I thought it was a waste of $$ and please just give me the antibiotics. They are going to but didn't seem happy about it. I told them they stay together in the house, run together in the same pen, walk the same places so to me it just seemed silly to spend the extra $$ for a test and then still have to spend the $30 on antibiotics. Would you have paid the extra $75?
