yesterday for a check up and his last round of puppy shots. He's 16 weeks and weighs in at 30.4 lbs. He's getting big. I also have a question. I asked this before but I didn't get too many responses. Has anyone's dogs had the Lyme's vaccination? We do get lots of ticks around here and they seem to be really bad right now. Just wondering if it's something my babies should get. Oh, and I also made an appointment to get him nuetered and microchipped on the 23rd. He's doing great!
