If you find a tick on your pet or on yourself, it is important to know how long the tick fed before you discovered it. Was the tick flat (then it recently attached) or engorged (meaning it had fed for an extended time)? Research conducted has indicated that transmission of Lyme Disease begins at approximately 24 hours after tick attachment. Other diseases may vary. Proper tick feeding stage identification can assist you in making a decision on whether to visit your doctor if you find a tick on yourself. The decision is yours. If you keep the tick to show your doctor, protect it from dehydration by wrapping it in a damp (not wet) paper towel. Should dehydration of the tick occur, it can be extremely difficult to identify.
