Afternoon guys
Now this is a long tricky one but I'll try and explain the best I can
5 weeks ago I got a call from a so called friend who was desperate for somebody to look after his dog as he was moving house and allegedly couldn't take this dog.
I collected her and I kid you not she was in an undescribable state!! She had dermodex mites and you could see her ribs/hips as well as her being covered in sores all over her legs and belly!!!
I took her to the vet who treated her and I've been getting her in good health whilst having her
This "friend" said he had rescued her from someone he knew.... All lies as I chip checked her and found out she wasn't the dog he said she was. He said she had a different name and also a different age to what her chip details are.... I called the registered owner on the microchip and he told me he gave the dog away 2 years ago and not to the person I got her off.

I've asked this person when they will be collecting the dog to take to their new home and he then asked me if I'd buy her....
For £500!!!!!
I said no! I don't want to buy the dog although I feel so sorry for her and don't want him to have her back as I know what condition she was in but I can't really keep her due to already having plenty of dogs.
She's not worth £500 but I did offer £100 just to stop her going back to this person but he wouldn't except the offer.
So I asked him to collect the dog.... Said he would yesterday..... Nothing.
Asked again today... Nothing again!!
What do I do?? I've paid to look after her for 5 weeks including vet treatment and this guy is a complete a**hole
Any advice kindly appreciated
