One study found that 20% of the ticks in an area where Lyme disease was endemic carried the spirochete. In another words possibly up to 80% of the ticks attached to our dogs are non-infectious. Also other studies have found the host developes a hypersensitivity (i.e. allergic) reaction to the tick antigens. The result is that the immune system on this heightened state of alert (i.e. due to the presence of the tick) is able to detect and kill any spirochetes transmitted by the tick.Originally Posted by mikkehla
If it were my dog I'd just observe it for the next few weeks. If it suddenly develops lameness or a GI upset that just as suddenly disappears, then a tick titer test might be worthwhile. Note also even if infected, it could take up to 6 months with Lyme before a strong antibody response can be picked up. As Catlady suggests the quickest and most accurate means of detecting Lyme is by culturing it from the tick.
