Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. I’m sorry to hear that Lucky ran off but I’m glad he is back with you. I would recommend bringing Lucky to your veterinarian as soon as possible to have all of his ticks removed properly. Ticks can be challenging to remove and if not done properly, can form abscesses in the skin. Ticks carry a number of diseases such as Lyme disease, anaplasmosis, ehrlichiosis, and Rocky Mountain spotted fever, that can make dogs very sick and have long last effects on their organs. Some of these diseases, such as Lyme, require the tick to be on a dog for 24 hours before the dog becomes infected, so the sooner the ticks are removed, the better. Your veterinarian will want to remove all of the ticks and likely submit bloodwork to evaluate Lucky’s blood cells and kidney and liver function. Also, if Lucky is not already on a flea and tick monthly preventative medication, I recommend asking your veterinarian about starting him on a topical or chewable medication that will help prevent infection with these tick-borne diseases in the future. I hope this is helpful!
