Just because you haven't gotten caught yet doesn't mean it's a good idea...
But it's your decision. The one thing I do want to point out though for this time or in the future is be careful or mail order/buying at tractor supplies. Certain vaccinations that need to be at a certain temperature become less effective when left at room temperature for too long. So if for example you get it from a tractor supply store, they could have left it out before refrigerating it which could affect the shot. This is just going off of what my vet told me and what I have learned so far through vet tech schooling.
Hmmm I never thought about that... I knew they like package it with an ice pack but yeah what if it got hot or something but my old barn owner used to order her shots and still do and they havent had any ill effects on the horses... so I think as long as I stay with the same company or I get it from my vet(which I might do) then I am good... thanks for the info!
