Many dogs with Lyme disease have recurrent lameness of the limbs because of joint inflammation, according to petmd.com. Others may develop acute lameness, which lasts for only three to four days but recurs days to weeks later, with lameness in the same leg or in other legs.
Better known as “shifting-leg lameness,” it is characterized by lameness in one leg, with a return to normal function, and another leg is then involved; one or more joints may be swollen and warm; a pain response is elicited by feeling the joint, and it responds well to antibiotic treatment.
Some dogs also may develop kidney problems. If left untreated, it may lead to glomerulonephritis, which causes inflammation. Total kidney failure sets in and the dog begins to exhibit such signs as vomiting, diarrhea, lack of appetite, weight loss, increased urination and thirst, fluid buildup in the abdomen and in the tissues especially the legs and under the skin, according to petmd.com.
Ticks transmit two other diseases besides Lyme, Dr. Esplin said: anaplasmosis and ehrlichiosis.
