Once a tick has been on your pet for 48 hours or more, they become engorged with your pets blood and can now transmit lyme disease to your pet. This is why it is so important to do daily tick checks and remove the tick as soon as it is found. If an engorged tick is found on your pet, we will wait 2 months and perform a lyme test. This is a test that we can run in house and only takes 3 drops of blood. The results will develop in 10 minutes. This test can also check for other possible tick borne diseases that may have been transferred to your pet.
