Wouldn't feel bad about the behavior of your basenji. I got mine six years ago and he acts a lot like yours. I kennel trained him and when I have company he goes in the kennel till he settles down. When I let him out I just tell people to be still till he checks them all out then he is fine. A lot of times he acts like he is going to attack me if he doesn't get his way vicious snarls and all, but I have learned it is just that an act . He also acted vicious around other dogs but after introducing them properly he gets along great. We have recently got him a new basenji mixed sister to play with, after the snarls and viciousness he loves her very much. I wouldn't be afraid to rehome your basenji, it at least give someone a chance to see what they can do.
You are right to find a vet that is familiar with the breed, I had a very bad experience with one that didn't understand them at all, every since I left him there to be neutered, he has had terrible trust issues. Then I also found that her vet tech hated basenjis, So don't be afraid to question them on how much they know. I was a new basenji owner at the time, my guy is 6yrs old now.
You might want to try a better quality of food and try grain free… many dogs don't really do well on lamb.... I love Fromm's Surf and Turf
I think It may be owner error , When everyone started throwing questions at me I got to thinking about his eating habits, he does eat his food but I wondered if he was eating enough as he has gotten a lot of treats through out the day, for doing good things, maybe to many which have no nutrition to speak of. So I have cut back on them, and since he would rather have them then his food. I give him some canned food with the hard food and he thinks it is a treat. So hope this works. I think I can tell a difference already or maybe it is wishful thinking. We are still taking a trip to the vet also, to check on red dry spots on his tummy. So thanks for all the input it has helped me think more clearly on this.
Are you saying that I should just pick his food up and let him have access to it a few times a day, I feed him Pet Smart authority lamb and rice. I also feed him a couple tablespoons of canned food a day ,he also gets training treats and other treats. I am going to try the vet again to see if he has lost any more weight. He lost a few oz. the last few times I have had him to the vet. He is very hyper active as I guess most Basenji's are. I tried to send a pic. of him with my first message but have a hard time figuring the photo page out. I am communicating with his breeder long distance I text her a pic. of him and she also thinks he looks thin. She is trying to help figure it out.
He has been dewormed and is current on all medical. The vet doesn't seem to think he has anything physical wrong, but she is not familiar with the basenji breed. I sent a picture to his breeder and she also thinks he is to thin. She has been trying to help me figure it out long distance.
