Acrid breath from my female JRT

[Shmee]

Hey guys,
My 1yr old spayed female JRT is having a small problem and I wanted to see if anyone had some better insight on it than I do.

Kaytee will from time to time, have an acrid sweet smell to her breath. It isn't foul so to say, but it makes me question why it's there. My male 3yr old eats the same food, Dick Van Patten's All Natural Brown rice and chicken and he has no problems. They both get healthier table scraps, biscuits and other small treats.

Other than the acrid smell, Kaytee has no other problems visible. She has her yearly checkup in 2 weeks and I am going to run this by my vet and see what she says.

Any help or similar experiences out there?

Thanks guys,
