Husky not eating regularly

I have a 1-year-old female Siberian Husky (~50 lbs) who has just recently became finicky about eating her food. We feed her 1.5 cups of food twice a day, which is the recommended amount from what I have read. A couple months ago she just stopped eating when we put her food down, and has to be coaxed into it and rarely finishes it all. We’ve taken the fact that she doesn’t finish it all to simply mean she doesn’t need as much, which is fine, but the behavior toward her food in general is what concerns us. She will simply ignore it until coaxed to eat, and while eating she acts as if it is unpleasant. When she does eat she will pick a couple bits up at a time and carry them to another corner, then nose them around for a minute before eventually maybe eating them. We have switched flavors twice, and both times she gobbled up the new flavor for the first few days but then returned to this state of disinterest. She shows no other outward signs of pain or discomfort, so I tend to discount that there is something wrong with her teeth or that she is sick, but we can’t figure out exactly what brought on this change in behavior or if we should be concerned about it.

In the next few weeks she will have a couple kennel stays and I am concerned that she will end up going without food there because I don’t expect the kennel workers to coax her into eating. We are also growing tired of having to do it every day and don’t know if she needs a trip to the vet to evaluate the situation. Since there are no other signs of illness I feel that it’s likely just a phase and she will eventually grow out of it, or perhaps we are just misunderstanding the behavior, but I’d like some other input on the subject.
