No fluttering or butterflies. My Apple Watch doesn’t note any arrhythmia, just tachycardia. Thank you for your response. I think it was just transitional as this has gotten better. Thanks for your response.

Do you feel fluttering or butterflies under your sternum during these episodes?  An irregular heartbeat or arrhythmia will cause shortness of breath, and it may be brief.  Electrolyte imbalances can cause arrhythmia, but it can also be caused my much more serious issues.  

Thank you for your response. My fiancé and my father are also experiencing this. Will definitely try to increase electrolytes as well as more water. 

Awesome!  Thank you

No.
How long does the shortness of breath last? A few minutes or a few hours?
You may want to consult a doctor, as shortness of breath due to a carnivore diet shouldn't be a thing. A lack of electrolytes causes a variety of symptoms, but shortness of breath isn't usually one of them. 
Do you have any pre-existing conditions such as kidney disease or diabetes? Do you have GERD, asthma, anxiety, or panic attacks?
Try taking a small dose vitamin C supplement. This usually isn't an issue, but we don't know exactly what your particular personal diet consists of either. 
 

I use Myfitnesspal myself. Whether that is the best or not, I do not know. 

The first thing you may want to do is check your blood pressure, it may be something that requires a doctor. Check whether you get all your electrolytes and minerals, could be a deficiency.
