My horse that had lyme was stiff lame in the hind end. Would work out of it after 10 minutes then was fine for rest of ride. Would be stiff lame next day this went on for months.
Then he started going lame in front then shortly after that he went dead lame on all four hardly could walk. It took over 3 months before he stayed lame and was very very sick horse.
I had never dealt with lyme before so had no clue till he got super sick.
