Sounds Easy:

 One of the most important parts of Rex's heartworm treatment is to keep him calm so the dying worms don't break off in large chunks and cause blockage in vital organs. If his heartrate goes up the risk is greatly increased. That sounds "easy enough" but in reality it is not as easy as it seems. 

Take last night for example. Some of our nearby neighbors were setting off fireworks and firing guns until almost two in the morning. That set two of our dogs into full blown uncontrollable panic.  Calming  Rx did not faze them and they were totally out of control. While Rex was not directly effected by the loud explosions he was indirectly effected by two full blown out of control dogs.  

Under normal circumstances we have been able to keep him calm but then there are inconsiderate people who we can't control that impact our lives. While fireworks are illegal in NC it is not something the local law enforcement is willing to handle. It was not a good night and seeing two of our dogs in full blown, uncontrolled panic and not being able to help them was a nightmare. For five hours they were in full eye bulging panic.
