Nice reply Grif.
As with any new pet, research before receiving the pet is the best course of action. But, its going to happen, pets purchased from pet stores with bad store advice, no prior research, and spur of the moment purchases will continue no matter how we try to apply what we learned to a new pet owner. Many only find us after the purchase and an issue arises or they want to now learn. Although we take so much to heart, we have to remember that our best course is to try and help and keep the member coming back so that he/she learns to better the life of their pet and then maybe pass on what was taught.
As for needing to euthanize. its a hard thing, and everyone has different tolerances to what they can bring themselves to do, no matter whether its the right thing or not. No matter how big and tough they seem or how meek and soft spoken they are. I'm cold and tough when I need to be and sad and broken when its over and alone. Others are different and some can't bring themselves to do this and some can. Just something to keep in mind when we want to help since we're going to get many different responses when it comes to putting down or losing a pet.
