My first B started challenging at 16 months, we neutered him shortly after and it did seem to help a little. However it was only a small part of the solution not the whole solution. The closest thing to a magic solution is the excercise and mental stimulation. Basenjis are one of the most intelligent dogs and need more excercise and stimulation than most. I have generally found males to be much easier to work with and less aggressive than females. Correct discipline, structure, positive reinforcement, patience / stubbornness and enough excercise are the keys. Usually when people have problems with their dogs it is the humans which are the cause, not the dogs.
Sounds like he is challenging you and he is about the right age for it. Two important questions, is he neutered? If not that may help. Second who walks him and for how long? He will probably need around 2-3 miles a day with structured walks. Other than that behaviorist yes.
Yes you can be unlucky with anything, but doing everything you can to ensure a healthy dog should be the top priority.
My girl has had blood work every year just as routine after my firsts problems. She has no symptoms, we just caught it on the yearly two years ago she slightly elevated, last year she was more elevated.
We first started just Nutramax denamarin, three months later it made no difference to her readings.
We switched her to Dr Dobs detox diet and Nutramax denamarin, went back after three months and her levels went up!
So now we have her on regular food, denamarin in the morning, milk thistle in the afternoon and twice daily 1000mg of fish oil.
Due to go back in February and see if that works. If not we will probably have to ultrasound. All her other blood work is normal so that is a good thing.
I had a male when we introduced a female puppy, they got on well. Then the male passed so we had a six year old female and introduced a nine month old male, they get along well.
My best advice would be to introduce them in summer on a nice day, during a long walk. Start by taking you dog for a mile or two, then have the new dog walk along with you for at least a couple more miles before heading home.
That way they will both be tired and used to walking together on neutral ground.
So sorry for your loss, I lost my first buddy four years ago in March and I still miss him. I got a new buddy a month after he died despite reservations over whether it was too soon\the right thing to do. So glad I did, just as my first wriggled his basenji way into our hearts, my new buddy has done the same. I still miss my first and always will, but another basenji knows just how to help you heal, the really are a special breed.
Having been a 'dog person' all my life I decided to get a dog after starting a family with my wife. Tried the local shelters but couldn't find a dog that I felt was 'right'.
My first B came from a pet store, I knew nothing about Basenjis and the owner said they are great dogs, good with kids and very loyal etc, he came with an AKC pedigree. I figured he would be great as he had a pedigree.
Many years later I found out by research he came from a puppy mill in Kansas. His health was problematic after the first two years, he was also prone to pancreatitis. At six years old he developed diabetes, with the constant testing, insulin and needles. It worked out around $2000 a year for five years until he passed at eleven, so around $10,000. Still, I didn't really care so much about the money as he was such a good dog. The constant care was hard, he needed monitoring almost 24/7 as he was a brittle diabetic and his sugar was hard to control. Many late nights staying up late and every morning was early to test him.
He coped with it well although I know he did not like the injections sometimes, we got different size needles which helped and became experts at injections. Still, I would wish no dog to have to go through that.
Our other two Basenjis we got from a reputable breeder, our oldest is ten in a few days and has been very healthy her whole life. She is showing elevated liver enzymes now on routine blood work but shows no other symptoms. Our youngest is three and is also very healthy.
So, to me it seems insane to buy any basenji without full health testing and from a reputable breeder.
Growling is only the first step, if not corrected it will get worse.
I never attempt to touch a dog that is growling, as the top dog you should never do that. Try telling her to get down but do not attempt to touch or grab, it may take a few minutes but is worth it.
The top dog never has to do more than persuade the lower dogs, nor do they try.
If that does not work, leave her collar on with a leash of maybe four to five feet in length. When she settles you can then grab the leash when it is bed time and gently pull her off using the leash.
With Basenjis determination, a positive attitude (you are going to move) and stubbornness work best (you are going to move no matter how long this takes).
At one year she is challenging you somewhat, it is very common once they are adult between one and five years old. Never scold her or get annoyed, just be calm, determined and stubborn.
Also consider more walks, chasing squirrels in your yard is excercise but the walks you take her on should be long (at least two thirty minute walks a day) and structured. When she chases squirrels in the yard she is the leader, when you walk her you are the leader.
