God takes care of his critters and provides a home for them. Sad but true. Losing a dog was always a horrific event but I think this goes beyond what is reasonable.
Think about it as private donation for research. Not excessive spending on a pet. I love dogs but can't afford that type of expense. I have to provide for my family first.
However those who have money and no children will often spend the type of money on a loved pet as they would have had on a child.
Besides, it is their money to waste as they choose..
Our golden/brittany mix, Samantha, developed lymphoma, and we tried chemotherapy. Sam kept going into and out of remission and after 3 months we were forced to put her down. I have no idea how much we spent; I never totaled the bills, 'cause she was worth it.
Looking back, I don't believe we would do it again. It was hard on the dog and hard on us. Two months after Sam died we adopted another 'older' dog, Gypsy. There are always 'thrown away' dogs who need homes; and 'the hole in one's heart' left by a dog's death, can be filled by tending to a new dog.
If these folks can afford it, more power to them, but this dog will not live forever. Ultimately, they will have a hole in their hearts left by this dog's death and they will discover that healing will occur with a new dog.
Well, it is in the kill-the-babies, save-the-whales state.
