Recent studies have shown that doesn't seem to affect separation anxiety as much as previously thought. More study is needed, but if your dog doesn't have separation anxiety, it doesn't seem like having high excited energy when you return will increase their chance of developing it.

From the abstract

"From both experiment 1 and 2, our results indicate that high excitement and playful levels of owners during departures and arrivals is not associated with the development of increased separation-related behavior in newly adopted dogs. It is important to make the distinction, however, that low arousal departures and arrivals are a well-documented treatment for separation-related behavior, and our results only reflect that these arousal levels do not appear to play a causal role in the development of an increased frequency of them."
