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.
