Good that your B-boy is on medication to help with his various issues. He is only 4 years old and that is very young to conclude that his behaviors are unchangeable. Those of us that have worked with rescue Basenjis know that behavior changes take time. I have had some sad little dogs with weird behaviors come through my home. I had the luxury of being able to work at home and work with the dogs more hours than most. Behavior change takes time and with the anxiety issues your dog is displaying it will take longer than most. You are very good people to see this "project" through.
Did you get any help suggestions from any of the Australian Basenji clubs?
You might want to talk to you vet about antidepressants or antianxiety medication for the dog (not you 
).

njdeb,
You are talking about Sue Coe of Akuba Basenjis. She retired to Oz a few years ago but is still very active with the Basenji Club of America (BCOA) as their website management chairman. I have her book too. I met her years ago quite randomly at a local dog park where she was meeting another Basenji breeder to evaluate a couple of B's for potential breeding (mine did not meet her standards even though a show dog). She is a strong personality (does not suffer fools) but I am sure that she more than willing to help advise reneemay about his dog. Her contact address is jcoe@bigpond.net.au.
@njdeb You purchase cans of pure pumpkin at the supermarket. If you live in the USA, since it is so close to Thanksgiving, you can purchase a case of canned pumpkin at Costco for a good discount.
At least Basenjis aren't too heavy. You can carry them around your neck and they won't protest, at least none of mine have.
Most difficult thing I have ever done in my life was to set my beloved tri Ella free at age 14.5. I am so very sorry for your loss.
@reneemay I am an American but for two years I lived in Geraldton, Western Australia, about 450 km north of Perth. Not much between the two places - a road house and dead kangaroos. I understand the challenges of living in (relatively) large but fairly isolated communities. Interesting times.
@reneemay Castration is likely to have little to no effect on your boy's behavior. Do not count on it helping you. Have you contacted the nearest Basenji club to you for help and advice? Not knowing which state you live in makes it difficult to to give you more information specific. There is the Basenji Club of Victoria - http://www.basenjiclubvic.org.au/ , the Basenji Club of NSW - http://www.basenjiclubnsw.org/ , the Victorian Basenji Breed Association - http://www.vba.org.au/ . These organizations could be useful in helping you find the best professionals to help you with your Basenji boy's issues.
Good luck.
