The very first time, I was put a the life or death situation, was many years ago, (of course, in the middle of January), when a little Dachshund, walked into it's families swimming pool, and proceeded to sink immediately to the bottom of the pool! These little short legged pups, are a little bit, like rocks with legs! Just not built for long distance swimming, or any other kind! They are , perhaps, better built for sponge diving in the ocean! (as long as there is a lifeguard on duty!
A responsible Pet Care professional, or not, will do as I did... and jump in the pool to save the pup! I did, and the little girl was ok! I'm no hero...only someone that knows how to make responsible decisions, based on the events at hand! Sometimes you don't get much of a chance to think, only the choice to respond (or not)! If this sounds like an advertisement for my services, then, maybe it is! I don't take chances with my own animals, and I regard, your animals as mine, while under my care! I have studied animal first aid, and feel comfortable in most any sort of emergency! I feel that this is one of the things that separate a good Pet Sitter/ Dog Trainer, from one that perhaps, should be passed by, as not a good choice to watch your precious babies!
