I tried for over 2 years to re-home a dog via about 15-20 rescues. I live rurally in a house with land, I have older DC, one of whom is mostly home educated and I'm self employed so home most of the time.
All except one turned me down without even speaking to me because our garden isn't securely fenced - whilst this is technically true, the actual "garden" is in fact only a very small portion of our land which extends to 30 acres of meadow, orchard, and fields - all enclosed with stock-proof fencing. We are nearly a mile from a tarmacked road, and our farm backs onto a large woodland nature reserve. I tried to explain that I was happy to keep a dog on a lead to cross the garden and only let it off once in a secure field with the gate closed, but not one rescue wanted to hear it. I tried sending in a screenshot of the OS map showing where the house is and how we would be able to only let a dog loose in secure fields, but that didn't help either.
One rescue did agree to do a video home check, but then turned me down because of our existing animals (1 cat, 2 peacocks, some chickens and a few sheep).
I refused to even consider buying a dog from a breeder for a long time as I was concerned about puppy farming and also the money being asked - £1.5-2k for a puppy? Jog on!
And then a friend mentioned my search to her parents, who were breeding one litter from their working border collie (crossed with a working black Labrador). They had several homes lined up already but contacted me and said they'd let me know if anyone changed their minds. We got lucky, and for £400 (including jabs, microchip, and 4 weeks insurance) we now have the Best Dog In The World ™️, raised by people who genuinely adore her mum and took the time and care to give her the very best start. They have no plans to have another litter (in fact I think her mum has since been spayed) and every single puppy went to people they took the time to talk to, to question, to make a careful decision on. I was the only owner they didn't already know personally, but as their daughter knew me they were willing to consider us.
I'm sure I'll be told it was unethical, a backyard breeder, that if rescues deemed me and my home unsuitable I should have accepted it and remained dogless. But... she is so happy, so healthy, she truly is living her best life here with us, she gets woodland walks every day, she spends hours following us round while we are doing farm shit, she gets fed properly and always gets the broccoli stalk and has been an absolute joy to train. And, dare I say, she has brought us so much joy...
