Hi all, looking for a bit of advice. First time breeder here and sold a pup to this lady who I had sent daily photo/video updates. Even collected her to meet the pups when they were old enough, paid for all their vaccinations and agreed I would collect the pup again to take her for her 2nd dose. Within a week of having her she asked me to take her back as her other dog was barking. Absolutely agreed and said I would be over after work. She then spent the rest of the day messaging me not to come and she just had a bad night etc etc. I still went for a cuddle and discussed ways to stop her other dog being jealous etc. Got regular updates from then on about how well she was doing. Suddenly 3 weeks later, she tells me to collect the puppy it’s not working out. Duly collected, whilst driving home (50 min round trip) she is already messaging asking for her money back. I get the pup home, she is no longer toilet trained, head shy and very nervous. I replied that at that moment I wasn’t sure what I would be doing with pup as she had some behavioural issues and would be in contact if or when I rehomed her. I have then received a barrage of threatening and nasty messages from her which I haven’t responded to. Whereas once rehomed I was going to offer her some money back she has been so rude to me without reason that I do not want to have any contact with her at all. What are your thoughts?
