I love dogs, but I'm not sure if I could own one. I grew up with dogs in the family, and was there when they were inevitably put down. What will always bug me is dogs rarely die of natural causes. We make the decision ourselves to kill them when we decide it's right, based on whatever illness they have.
As much as I love 'em, I don't want to watch another dog slowly get old and crippled in it's twilight years, until it can hardly get out of it's basket, and then decide for myself to terminate it's life, without it having a say. It's very easy for people to say it's the kind thing to do, but really, most of the time people put their pets down to avoid their own personal pain at watching them suffer. It's for their benefit. They just convince themselves, the arthritis ridden pet, who's in discomfort, and a bit sad he can't walk easily any more, is desperate and pleading to be murdered.
My legs are sore, and I may piss on the carpet. So PLEASE KILL ME NOW!! You're kidding yourself.
Sorry to post a depressing rant like that! It's just a strong feeling I have had for many years and this thread just made me think of it again.
