I'm so glad I'm not the only one that feels this way about certain rescues, if I mention my issues with some local rescues to people I know they act like I'm a monster advocating for the execution of all fuzzy and soft animals. A lot of the rescues in my area are so stringent about their rules, insanely expensive and some of the animals requiring a lot of medical care, I don't know how they find homes for any dogs at all.
We had a really negative experience when we were looking years ago, we were looking for an older rescue dog and applied at a pet fair, put a deposit and completed the interview process. They said we were approved (FIL lived with us and was home full time so she wouldn't be home alone or crated) and could pick the dog up the following Wednesday after she cleared all of the tests but they never called, I called them for a few days and finally reached someone who told me that the dog had been adopted to another family that had a fenced in property so we were out of the running but they would happily accept our deposit as a donation to their organization. Uhhh..no. We went to the SPCA that day and paid $250 for a dog that was up to date on her shots, spayed and gloriously trained.
I got into it with another rescue lately when we went to a pet fair, we brought Huntley and a woman asked us what breeder we had purchased him from. I explained that we actually came across him online and his family was giving him away for free because they were getting a divorce and neither person was willing to commit to a 5 month old puppy, she literally started yelling at me in the middle of the pet fair and said that by getting a dog online I was contributing to backyard breeders and that my ignorance about what a real rescue is causes a lot of problems for people that REALLY care about animals and that as long as breeders were making money off of people like me innocent dogs would continue to suffer. I tried to ask her how I was contributing to breeders when I got the dog for FREE but she was so busy ranting at me that she didn't answer so we just walked away. We were at another adoption fair last year and overheard two volunteers (loudly whispering) that they hoped we didn't apply for a dog adoption because Huntley could use to lose a pound or two and they didn't want one of their babies to go to a family that would turn them into fat pigs.
If and when I get another dog it will be through the SPCA, I know there are people that work/volunteer for rescues that are amazing people but I was so turned off by these people I wouldn't go through that process again.
