I’m so sorry you have to go through this. Even though you are located in Spain, I would highly recommend reaching out to BRAT to see if they would be willing to help you re-home, or to see if they have any contacts there.
Looking Male basenji puppy before the end of this year hopefully (uk)
Looking for a reputable breeder in the uk for a male basenji puppy
Try Sally Wallis of Zande basenjis. She maintains a catalogue of Basenji stock from year dot, and updates them regularly. She may have some or know of some, but look at her website to see if you pass her acceptance tests.

Read the Put-Off and other articles on www.zandebasenjis.com first and then email me privately. There is one about not doing the breed a disservice which kind of follows from the put-off.
Then email me privately. There is an address on the website. Don't forget to tell me whereabouts you are in UK.
