At what age are they letting you have the puppy? Most responsible breeders don't let them go until they approximately 10 or more weeks old. Tails take awhile to grow and loop more. At a month old the tails normally look much like your photo.
Make sure you have the registration numbers for the parents so you will be able to easily find the on the OFA site.
Engage a behaviorist, someone with qualifications who will work with you to help you change how you deal with Blu. Blu has had a lot of changes in a very short period of time and you are expecting a lot from him. If he never had much experience with small children he may be trying to nip her out of fear. Children are unpredictable, make quick movements, and are loud. Blu likely is terrified. As stated above, neutering will not change his behaviors.
You can contact nearby breeders to see if they have any older Basenjis (returns, failed show dogs, never going to be bred) in need of a home. The Basenji Club of America web site has breeder information by State but you should email Denise, the breeder contact, for additional breeder information.
I recently purchased these seat "tethers" for the car. You need a car that has latch bars for child car seats (required in US cars after 2-27-2014). I purchased two because I was picking up a new older dog and did not have room in my car for a crate (2000 mile trip x 2). The carabiner latch is easy to use. I was concerned they might chew the straps but so far so good. I read too many account of Basenjis slipping out of car harnesses or getting tangled up in them on various Facebook groups. These tethers are working very well for me. My dogs wear martingale collars (when they wear collars). http://a.co/4Z873Wy
Whatever you do, do not purchase anything that secures using the normal seat belt latch. The seat belt latch can break or get jammed and can cost you plenty of dollars to fix.
My old girl Ella had a shattered rear leg from being hit by a car. My options were amputation or surgery. I opted for surgery. She did have a plate inserted but that was because she had bone pieces removed and the plate was there to connect what was left of her leg bones. We had casts, lots of casts. The vet told me to keep her quiet, not let her roam around, absolutely no stairs, and to wear an e-collar if not well supervised. Ella did not listen to the vet. I blocked the stairs with a baby gate but she managed to jump it while wearing the cast which went all the way up her leg. She perforated her e-collars to where I could use them as colanders. I also had to find a high calorie food (not high protein but high calorie) because the veterinary surgeon said she would need twice the caloric intake in order to heal quickly. I ended up hand feeding her a mix of kibble and canned food. She healed fast and well. Ella ended up with a slightly shorter rear leg but she could still run like the wind. She lived 11 more years and died at age 14.5.
I have seen photos of the halo type device on one of the Facebook groups, "Basenji". You may have to join the group but here is the link to the post https://www.facebook.com/photo.php?fbid=1904813413071092&set=gm.1407068002664730&type=3&hc_location=ufi
I am sure you can contact the owner of this dog, Maria Eriksson, but please remember that English is not her native language as the "Basenji" group is international.
@debradownsouth My editing of my post was terrible. Thank you for clarifying what I meant to say. I did have a female that tested "probably affected" in the early testing. She was bred to a clear (later most accurate test) and produced 3 pups who were all carriers (again, the latest most accurate test). While I found it necessary to put her to sleep at age 14.5 (seizures related to brain damage from being hit by a car) she never developed Fanconi or any symptoms of it. None of the pups were bred for various reasons (development, temperament) although one did become a lure coursing champion.
How did you introduce the two dogs? Did they first get to meet in a neutral place? The lab is the invader of Blubert's "personal space", everywhere and everything in Blubert's home is his. You have a teenage dog and a middle aged dog, how would humans in those age ranges do together? You should probably consult with a behaviorist to see what you can do to "fix" things.
Here is a link to the American Kennel Club's web site page that lists and explains the various breeds of dog considered hypoallergenic. Basenjis are not on this list.
All dogs can bite. You may be talking about chewing up belongings. We all have our personal experiences with our belongings being chewed up. In my experience, Basenjis can and will chew up your stuff until they die of old age.
