I'm with one of those "power tripping" groups, and I agree we do go to some extremes. Mainly because the animals we've rescued have come from unfortunate situations where they were treated as disposable. My group (Animal Rescue of Tidewater) uses foster homes and has limited space as to where we can put a dog or cat once we get it out of the pound or where ever it comes from. We do such a thourough check (personal references, vet references, lease or mortgage check) because we want to be certain that animal isn't going to be returned to us.
If you really want the animal, you're willing to put up with these things.
With all the contracts and statements signed, we've still been wrong about the home. Out of the 72 cats I rescued last year, 2 came back home to live with me, and 4 were re adopted to people that DIDN'T lie on the applications. Out of the 12 dogs I rescued, only one came back 2x (I hadn't personally done the checks and took another member's word on it) and only one did I have to re-rescue because the Army Warrant Officer was a liar. Apparently "I'm taking the dog to GA with me" means "I'm leaving the dog with my mother who hates dogs"
I personally don't agree with the need for a back yard for a dog. If the person tells me they'll take the dog to the dogpark daily (like I do mine) or they tell me how they'll let the dog out if it's just them and the baby is sick....you get the drift? If you've got a big back yard, doesn't that make it easier for you to just tie the dog up and forget about it out there? (I'm not saying ALL people with back yards do that)
My group has legal reasons that your other pets be up to date on shots and in compliance with city ordinances.
Hope Belle finds her forever home with you!
