Just to add, I think it is a bad idea to ever sneak out when they don't know you are leaving. This causes anxiety as they don't know where you are. Once leaving and returning becomes routine the dog shouldn't stress about your absence, but if he doesn't know you've gone and can't find you she may panic. My ideal, which I did achieve with Perry, is a dog that doesn't even bother to get off the couch if he's comfy when you return, just lifts his head with an "oh, you're back" look and accepts your presence as normal routine. After all, I don't expect most people greet their returning spouse with a lot of enthusiastic hugging when they've just been out getting groceries! Dogs are generally the same. If we don't make a fuss they learn not to either......which may not feed your ego but is less likely to result in anxiety over your absence if your return is no big deal.
I learned a lot from having two separation anxiety dogs in a row, both mature when I got them. We got to the place where they could be left without issues, and being very matter of fact and treating comings and goings as routine was key to achieving it.
The first thought that popped into my head is to make her happy that your leaving. Find something that is a high value treat for her that she really likes but only give it to her once you get home and once she is quiet. Praise her for being quiet and for being a good girl for being alone. Start with 10 min and then make it longer etc. If she associates you coming home as something good, she may feel better about watching you leave. I would also have on music she likes so she isn't feeling completely alone. My last piece of advice is a sweater. My dog hates putting one on, but as soon as she is wearing it she's fine and I find the warmth really calms her. I would put it on in the morning and see if she is a bit more calm and relaxed during the day. Good luck!
I adopted an adult basenji with some separation anxiety. At first I only left him for very short periods of time, but each time, I would prepare a special "treat" for him. I tried to mix it up - sometimes a paper towel tube filled with yummy treats, sometimes a sterilized bone packed with cream cheeze or peanut butter (or a combo). I save any small boxes to fill and tape back together. As the basenji watched me assemble the special treat, he associated my leaving with a good thing that would follow. Now, he nearly pushes me out the door so he can have his treat - the anxiety is for me to leave quicker! Sometimes I would prepare the special package ahead of time and then not leave for awhile. This made his anticipation for me to leave even stronger. The one drawback is if you use a cardboard box, then any cardboard box becomes fair game for dismantlement/destruction, even if it is not meant for that purpose (yet).
The only other solution I can think of is to get a second basenji to keep the first one company!
I have an old girl, just about 16, who is the last of four dogs.
I have to strongly agree with eeeefarm, that leaving surreptitiously, or quietly isn’t a great idea.
When I leave little Tess, I’ve found that it is important that I calmly let her know I am leaving. I get the things I take with me, my purse, etc., wake her from her slumber and say that I’ll be back soon. I am upbeat, but not excited.
She’ll go back to sleep, and will be fine when I return.
Should I be in a hurry and forget, I come home to a sad, mournfully howling basenji. I might even find an accident.
She just needs to know.
The fact that I was home so much did make it a little harder for her when I went back to work.
I love the suggestion of the Adaptil. Also that of leaving for short periods of time with a puzzle treat, or frozen peanut butter in a basenji sized Kong. Slowly but surely increasing the time you are away is a good idea.
Initially, 10 minutes may actually be too long.
10 minutes in puppy time is a very long time.
I am so sorry your little dog is having separation anxiety, but I know you will help your puppy through it.
Also, I don’t recall if anyone else mentioned it, but the time for calm indifference is when you come back into the house.
Come in calmly put your things down, go about your business putting groceries away, etc., then great you dog calmly and without commiseration.
If you commiserate with your pup, your pup will think he/she was right to be upset; thing are really as bad as he/she thought.
Don’t take too long before you greet your pup, just don’t put your pup first on the agenda when you come home. 
Pawla has the best idea. Get a second Basenji !
Totally agree with Zande that Paula has the best idea -- get a second Basenji!
Short of that, get the (e)book which Zande has recommended: The Culture Clash by Jean Donaldson. It has an entire section on how you can handle separation anxiety with a lot of step by step ideas. A lot of what she says has been offered here, but the book is more extensive and in depth. (The Table of Contents isn't the best but you're looking for "Dog Social Behavior and Its Implications -- Alone Training").
All these suggestions are great. What works for 1 dog may not work for another. Keep trying, don’t give up. A tired basenji is a good basenji. Our high energy boy that suffered from separation anxiety would go into destruction mode when we left him, even though he had his sister for company. I found that he needed to be throughly exhausted before we could leave him. Walking by itself was not enough. I gave him a job! He was very proud to do his ‘special’ job for Mummy. I backpacked him with 2 water bottles partially filled for weight. As his stamina increased, I added more water to the bottles. My husband thought I was ‘crazy’ and I’d never get the dog to go along with my ‘hairbrained’ idea. BUT because he was used to me putting him in a sweater/coat, the transition to the backpack was quite easy.

Love this idea! LOL
@rockonrush I think the easiest solution is to:
Get them accustomed to the routine with super fast in and out trips.
The idea is that your dog will start to accept you coming/going without the anxiety. I noticed that my girl was always right at the door when I opened it and worried that she was upset while I was gone. So I set up a couple in-home cameras and checked it out. I learned that she curls up on my bed after I leave. And she seems to stay there until I put the key in the lock. When she hears that noise, she jumps up and dashes down the hallway to the door, just so she can welcome me home. I can't ask for more than that!
Thanks everyone for the suggestions. I would love a second basenji!!!! Though I don't think I can afford one at the moment haha.
There's a lot of different suggestions which is great because one will probably work and several probably won't! The key thing that everyone agrees on is not to make a big deal when returning which I've already been practicing and it has good results each time. I will experiment with each suggestion in blocks and see what seems to work best.
Thanks again, and if anyone has more stories please continue to share!
First, remember you're dealing with a puppy - nothing will happen overnight. It always takes time to form a behavior. DonC's advice about not making a fuss when you return is excellent. So is BrindleBasenji's advice to tell your pup you're leaving, he's staying, and all will be well - you'll be back soon. I can't say for sure that b's understand everything, but I do believe it really helps them when you talk to them. I always tell my b what I'm going to do and what I expect. Maybe it helps ME stay in a calm focused/assertive mind. Whatever, it works. Finally, RGK9Ruler reminds us of an important fact: a tired basenji is a good basenji.
Get your pup tired out. Don't make a big deal. Tell your pup you're leaving. Leave him with a treat that will occupy him for a while. Don't make a big deal about your return.
A second basenji might not be possible, but perhaps you could borrow a friend's dog for awhile (it doesn't have to be a basenji). It has to be the right dog - a calm, well-balanced, well-mannered dog who gets along reliably with your pup and who does not exhibit separation anxiety. If you could have this dog live with you for a couple of weeks or a month, or even off and on, it might do the trick.
I think these creatures are so interesting! They are programmed to manipulate us to get us to do what they want! Be strong and be patient.
Let us know how it's going.

So do I. Always have. maybe its just the reassuring sound of Mom's voice but 'I have to go out now, will be back very soon and its raining outside so you would hate it anyway !' seems to help.

Talking to my dogs and horses has always been my way, and they understand more than you think. Dogs especially will learn to pick out the significant words, although they also read your body language extremely well. I would argue horses read body language even better!
One thing I have practised since reading Charles Eisenmann's books is teaching my dog specifically to listen and pick out the pertinent information in my verbal ramblings, e.g. I might mention in passing that "I would kill for a red bone right now", which resulted in Perry bringing me his red bone without a "formal" request to do so....of course, if you reward the behaviour you will find your dog paying even more attention and finding the information encoded in your speech. It's a fun technique. Another example when a dog is underfoot in the kitchen "be somewhere that is not here!" or a variation on the theme. My dogs understood me very well.....and learned the meaning of many phrases that could be spoken casually and result in a response from my dog.
"In order to get along with a Basenji, you have to be at least half as smart as the dog!"
@zande
I totally agree! I talk to my basenji all the time - I swear she understands what I’m saying! (I’ll only need to be concerned when she starts talking back to me! ) 
@eeeefarm said in Training to be alone:
I might mention in passing that "I would kill for a red bone right now",
My favorite on this theme is 'you get a bickie at the bench.
Especially since my hip and then knee replacements, I welcome the chance to sit on the (very few) benches in the forest. These are all on the main walkways and because I tend to go off-piste, I have various logs and low branches I have designated 'benches' for the purposes of communication, and to ensure that, from time to time, I can be sure of their whereabouts. They wait at them for their treats.
The dogs have always received a bickie when I sit for a spell. This did not stop Hoover especially, dancing backwards in front of me long before I stopped.
Those two words have been instilled into generations of Basenjis - and now Mku !
NB, these bickies are not extra treats, they are pieces of kibble I have removed from the daily food ration and put into my bum-bag.
Sneaky but saves unnecessary weight gain !
@pawla - Just a comment, I would not use the paper towel tube as you have noticed that they will tear/eat/chew cardboard, not really good for them and as you have seen, all cardboard is fair game. And I don't agree with the comment that 5 or 10 minutes is a "long" time to a pup... Dogs have no real concept of time.... in my 30+ years in the breed (Basenjis) if we left for 10 minutes or 8 hours, the response was the same.... excited to see us and if it was 10 minutes the greeting was the same as if for 8 hours
As mentioned above Kong is great, frozen Kong even better, it lasts longer.... I'd recommend leaving her inside the house ie go to a different room, garden, out the front, and ideally try and come back and reward her before she notices, no reward is she makes a fuss or comes looking for you. Camera would definitely help to know how bad the problem actually is.
Sorry to be so ignorant, but exactly what is Kong ?
@zande
Sally - it’s a rubber chew toy that you can fill with treats - like kibble. You can also fill it with peanut butter and freeze it.

Which is great... until you realize how many calories you've given your dog! I'm sure that's why doodle gained weight when I first got her!!
