I found a tick on my pup. Removed it completely and was pretty small, hasn't been in long. Should I be worried about Lyme disease? What are symptoms?

A tick must be attached and actively feeding for at least 24 hours before the Lyme organism can be transmitted. If the tick was not engorged, it has not yet fed. Monitor for lameness, lethargy, painful joints, fever or loss of appetite. You can present the tick to your vet for identification if you still have it. Consider a topical preventative, collar or oral preventative to prevent fleas and ticks. Discuss options with your veterinarian.

    There's alway a concern about Lyme disease transmission, but you did the right thing by removing the tick right away. Symptoms to look out for include a fever between 103F-105F, lameness, swelling in the joints, lethargy, loss of appetite, and swollen lymph nodes. If you see any of those signs, take your pup into the vet. Lyme disease can be treated with doxycycline.

    Clinical illness typically occurs 2-5 months after infection, however only about 10% of positive dogs will ever develop clinical illness from infection. So your dog may not become clinical even if the tick was carrying Lyme. The best thing is to screen for the disease with a yearly test, especially if you live in an endemic area for Lyme disease. Also, make sure to use a flea and tick prevention, like NexGard, Frontline, Bravecto, etc. Also, talk to your vet about vaccinating for Lyme disease if your dog is not already protected.

    I'm glad that you were able to remove the tick from Tom. Deer ticks need to be attached for about 24 hours in order to transmit Lyme disease. Other types of ticks can transmit other tick borne diseases, such as Anaplasma and Ehrlichia. In many cases, it can take up to 6 months for antibodies to develop and register on ELISA blood tests. As long as Tom is doing well, there is no need to take him to his vet at this point. Make sure that he is receiving a high quality flea and tick preventative once a month year round (examples include Nexgard, Bravecto and Adantix), and be sure to mention this tick exposure to his vet at his next exam.
