Okay, now I've read the entire thread...LOTS OF GREAT POSTS here! And I'm really happy to see that it has not become confrontational
That being said, here's my two cents:
Personally, I could never rehome Ginger, Bernie, Kirby or Mr. Fun Kitty...BUT, I don't want to discourage those who do. Anyone who is feeling the need to rehome should be supported. Think about the animals. What is better for them? To be in a home where they are at best ignored and at worst mistreated? Or to be rehomed to a place where they are loved and wanted? If someone is to the point that they want to rehome a pet (I'm not talking breeder here, they have an entirely different set of circumstances) there is a good chance that they and the pet will both be unhappy until this takes place. So why fight it? Let's help them find the best home they can. Sometimes personalities just do not mix!
I'd also like to say (admit) that when I was MUCH younger, we made an "impulse buy" and ended up with a dog we were in no place to handle. Yes, we did find him a new home. He was happier, we were happier, and our other dogs were happier. What did I learn from that???? Well, since then every animal (with the exception of Fun Kitty who just kinda moved in on his own terms) that we've ever had has been researched and fully committed to before we brought it home. No more impulse buys for us, every one I bring home now is here for life!
