Working as a large animal veterinarian in the summer has its challenges.  Much like other jobs that are outside, the weather plays a huge factor in how you do your job.  In this case, not only your comfort or ability comes into play, but the animals’ as well.  Heat stress and heat exhaustion can be deadly to livestock and horses.  Cattle are overly sensitive to this in most cases, and you often have to schedule appointments for them early in the morning to avoid causing undue stress or even death.  Most cattle producers in the south avoid breeding their cows during times when calving would be undesirable for the cow as well as themselves.  Afterall, if trouble occurs, you must step in and help.  No one wants to pull calves in subarctic weather, but neither are tropical conditions any less desirable.  I always dreaded getting a call for a cow in labor during the summer.  The calls always came in around 2-4pm (absolute hottest time of the day).  This meant that the calf was likely dead, and, in the summer, dead calves turn rotten very quickly.  You can easily find the cow in question as she was one with the multitude of large, green blow flies circling her very odorous rear end.  If you have never been exposed to decomposition, then let me describe a rotten calf still inside its host.  The hair starts to fall off with even small amounts of pressure, the skin starts to fall apart and easily rips when pulled on, teeth fall out of the mouth, and the entire body swells with bloating from bacterial growth.  All of this combined gives you a fragile, enlarged, smelly and overall, poorly manipulated subject to remove from an already tight space.  You will have to work to remove the disgusting dead body all the while being harassed by countless blow flies, sweat dripping into your eyes, decomposition assaulting your nose and a nasty staph infection on your arms for the 10 days after you are done.  If you are lucky and the cow is not a tiny first calf heifer that has no chance of delivering even a cat sized calf, you will be successful in your endeavor.  If not, you will likely have to euthanize the cow as a C-section is not a desirable option with this much infection present peritonitis is a sure thing.  Summer calving is not for the weak stomach or the faint of heart.  It is hard, dirty, smelly, exhausting and far from my favorite way to spend a summer afternoon.
