Our new puppy is doing well, she has been with us for 2 weeks, she's 13 weeks now, she was easy to potty train, has learned some commands, etc. However, for the last 2 days she’s been nervous around my husband. She was fine with him the first 10 days home, would go sleep on his lap or shoulders. But now if he tries to pet her, she runs off and trembles. Nothing has changed in our routine, it’s like she suddenly didn’t recognize him. Has this happened to anyone? I work from home so she’s fine with me. She gets to see my husband only in the evenings, when he gets back home. She's also great with our two daughters. My husband loves her and feels bad that he can't even approach her anymore. Oh and yesterday evening she started peeing on the sofa while looking straight at him... and she normally goes outside to pee... maybe she was upset that he was home? I told him to hand feed her this weekend, I’m hoping this will help but any other advice would be greatly appreciated! I’d like to fix this ASAP. Thank you! 
. Thank you for mentioning the fear stages, let's hope it goes by quickly! 
Hi - a few thoughts in case they are helpful, although ours doesn't bite.
For biting:
Figure out the reasons for biting first.
-if she does bite someone, then immediately isolate her in a basenji-proof room where she cant destroy things. And when letting her out, ask her to sit and be calm for a few seconds first so that she's not hysterical and she learns to watch and listen to you. There may be something else that one does for biting, so maybe others or a trainer would have good ideas.
For pulling on walks, 2 things worked for us:
A gentle leader - suggested by our trainer. This means she can't control her head (if they pull forward their head moves to the side like a horses halter) and so she won't be able to forge ahead. It will give your arm/shoulder immediate relief while you work on the rest.
In the yard and on walks start rewarding with small treats every time she looks back at you/checks on you. At first she'll do it by chance, or if she is checking to see what you are doing, and sometimes it's a side glance. As soon as she does it - give big verbal praise and get her to come to you and give her a treat and lots of pets. She will begin to do this more often. initially treat every time she looks at you, and once she is good at it, then randomly. On walks you'll find her looking back and coming back to you more often, and as a corollary less pulling, which is a relief. We usually keep the leash in one hand and a handful of small, soft treats in the other - so you don't run out and have to keep going into your pocket to get treats. So, she'll come and nose your hand and you can pet some times, treat sometimes, etc.
The one thing is to progress slowly, praise the right behavior and don't get impatient (count to 10, stop training or go do something else for a bit till you feel ready to try again). When doing the praise really have an excited voice and go overboard even! Our basenji really loves being praised. It takes more time perhaps than other methods, but it's long lasting because they see these behaviors as rewarding so you don't have to get into a battle of wills. And once they get the idea, they'll improve rapidly, even over one walk.
Good luck!
