This is a reach, I know, but does anyone have any data about Covid-19 infection in dog owners? 

As previously mentioned from the Nature published study, if we have been exposed to other coronaviruses, even not SARS or SARS-CoV-2, we can have T-cells that recognize and launch attacks against SARS-CoV-2.

It appears betacoronavirus is carried by dogs and impacts their GI and is short-lived. Humans can be exposed to it and not develop infection symptoms. But such exposure apparently creates T-cell reaction to SARS-CoV-2 that activates antibodies and kills the virus.

Puppies are most susceptible to Canine Coranavirus (CaCoV), but all dogs can get it. Having had two puppies 8 years ago who went to dog parks and have since had their share of “questionable” poops, my odds of exposure to CaCoV are high. It might be possible that some very minimal exposure to SARS-CoV-2 might have triggered antibodies from a previous CaCoV exposure that would kill it. How would I get tested to see if this is the case? And even not exposed to SARS-CoV-2, is there a test to find any previous coronavirus exposure that doesn’t rely on finding antibodies? We know the body clears Covid antibodies relatively quickly, which has made this puzzle that much more vexing.
