Notice illness, not just ticks
Low energy, loss of appetite and fever can occur with tick-borne infections, but also with many other illnesses. Pale gums, unusual bruising or bleeding are concerning. Contact a vet promptly if your dog seems unwell, whether or not you have seen a tick. Collapse, breathing difficulty or heavy bleeding needs emergency care.
Explain what has changed
Tell your vet when the illness started, whether you have noticed ticks, and which prevention products or medicines your dog has had. Bring earlier test results if available. Finding a tick does not prove an infection, and not finding one does not rule it out.
Ask what the tests can tell you
Your vet may recommend a blood count and tests for particular infections. Some tests look for the organism or its genetic material; others look for the immune response. Results need to be considered alongside the examination and the stage of illness. A low platelet count alone does not identify the cause, and further or repeat tests may be needed.
Complete treatment and follow-up
Treatment depends on the infection and how unwell your dog is. Do not use another dog’s prescription or start leftover medicines. Follow the prescribed course and return for the checks your vet recommends, even if your dog seems brighter. Ask which changes mean you should call sooner, and review tick prevention to help reduce future exposure.
