If you can, try to avoid it. My Darcy had his first at 10 weeks and the second lepto 3 weeks later (it is unavoidable in my country) .After the first he was fine ,no side effects or anything ,after the second he was very sleepy for 12-14 hours and after all bad things I’ve heard about the vaccine I’m worrying all the time for his liver . If you have a choice skip this one. |
