They sell to anyone.
Look at this: {Copied and pasted from an advice site}
''Hi, my 84 year old disabled husband and myself (76) have had a 10 year old Romanian rescue dog in our home for 4 weeks tomorrow. Prior to that he'd been in a foster home for 2 weeks after coming to UK.
**
Neither of us have experience with rescue dogs but we have both had dogs in the past.
I hadn't even realised that they'd be so different until reading about them on here. Miky was very shy and frightened to begin with but soon came to love his dog bed and spends a lot of time sleeping in it. He's been very good with his toileting, holding onto it all night and going in the back garden when he eventually gets up in the morning.
He's very picky with his food and I've tried him on lots of different types but he eventually eats what I give him and is rewarded with a dental chew which he loves. He seems to alternate between not wanting to eat and being so ravenous that he will eat anything.
Yesterday I picked him up and put him on the sofa which he seemed to love but when my husband tried to move him off, very gently, he was bitten. He's a small terrier type and is like Jekkel and Hyde. He has become very loving, wanting me to stroke him and putting up his paw for more but he will show his teeth and snap if he doesn't want to do something. I chastised him for biting and pushed him off the sofa. We didn't allow him back for the rest of the day, then today I let him on the sofa again but managed to move him off without getting bitten when I wanted to sit down.
He usually goes outside to do his business but last night he refused to go and peed in the passage. This morning he wouldn't go outside at all so I put his lead on him, with him skulking reluctantly and took him outside the front door where he did all of his business. I can't understand how changeable he is, one minute he'll happily go out in the back garden to pee etc then he won't go anywhere near the door.
Tonight he didn't want his dinner at first then wolfed it down and wanted seconds. This is normal for him but one minute he was a quiet, withdrawn little dog with his head down and next minute he's having a mad half hour chasing his tail and racing around the house, jumping up at me and looking very animated. He has had a few mad half hours, usually at midnight as we are going to bed!
^^
I just can't work him out and I confess I'm a little afraid that he's going to bite me when I least expect it.
Any advice will be welcome. Sorry this is a bit rambling but that's how he makes me feel!''
No way should an older {edit: inexperienced }couple have been sold a dog like this.
