Excellent video.

The PDF file says that the Leptospirosis vaccine is given in the right rear also ;)

Thank you Karla! As someone who hasn't administered a vaccine in years I appreciate you correcting that! Becky says it right in the video.

Great video! I just have a question about the reasoning for changing the needle after drawing up the vaccine, because my current practice does not and if I suggested the change in protocol, I'm sure they'd all look at me like I had 3 heads... Is it because the needle becomes more dull, or is it a sterility issue, or both?! Also, we typically don't use smaller vax needles (22g is standard, rarely do we use 25g for vax) for smaller patients because the general belief is that the injection takes longer and is more painful for the patient. Is there any truth to this belief? Thanks! :)

Samantha----the reasoning for changing the needles is to have a new, sharp needle for injection of the vaccine. Since the needle on the syringe has already gone through at least one rubber stopper and now will be going through skin, it is for comfort. That being said, most pets will probably not notice. I would like a new needle if it was for me (or my pets) so that is why we change needles. It is personal preference on the needle size, too. Some staff swear everyone needs a 25g needle and others that believe the 22g is better. The injection does take longer with a 25g, which is awful with a fractious cat, but may be more comfortable for the older cat (or very scared/nervous little dog). We try to do what is going to be most comfortable for the patient. Thanks, Samantha, great questions. Like most of veterinary medicine it is what works best for your clinic, DVM's and staff! :)

Here in CT we give lyme in the left rear and lepto in the left front and that is standard across the state.

It would be good if the checklist could be updated to correct the lepto misinformation.

Hi Lauren,

Thank you for the feedback! We have updated the checklist to now reflect the correct information regarding Leptospirosis.
