I'll give a bit of back story as it may help. Last year I bought a puppy, she is a dear little thing and has been no trouble at all (apart from the usual terrier puppy shenanigans!).
A couple of weeks ago the breeder contacted me as another of the puppies from the same litter has run into difficulties in his new home. The breeder wondered if I may be interested in taking him on. It turns out that the pup has been badly bullied in his new home by one of the other dogs there and has become very nervous and hyper sensitive. Not at all aggressive but he is a young dog and it is a danger that he may develop fear aggression as he matures. The current owners are out of the house for many hours in the day and cannot devote the time he needs. They also do not seem to have the experience required to handle the situation.
I have now been to see this dog (a 8hour round trip) and the poor little mite is terrified but a lovely looking example of the pedigree and clearly has a very gentle, sweet nature. The breeder also came to the meeting to help with introductions etc.
Having weighed up all the advantages (there are precious few) and disadvantages (many) I have agreed to take on the dog and attempt to bring him on. So I sent the owners a message expressing my interest and suggesting taking our dogs for a walk at a halfway point between our homes to make sure they all get on.
I have received a text back saying that they would be delighted for us to have him and that they want £500 for him.
TBH I hadn't even considered paying for him as I had it in my head that they needed a good home for a difficult dog. I am offering a good, experienced home but I will be investing a lot of time and money on him to get him right. I appreciate that you shouldn't give a dog away but if he goes to the breed rescue they will simply take him and then charge the new owners a fee, fair enough but the current owners will get nothing for him. I know that they have made a financial investment in buying him so I am willing to offer something for him.
I don't know what is a fair price for a 10 month old pup with behavioural problems?
