DULUTH — Cases of a serious and sometimes fatal fungal disease in Minnesota dogs are off the charts so far in 2019 as blastomycosis spreads in a wetter, warmer climate.

So far in 2019 there have been 170 cases of blastomycosis in dogs reported to state health officials, up nearly 50% from last year at this time and already topping the previous record of 155 set in all of 2017.

Exposure to the fungus starts in the spring, with reports peaking in October and slowing after snow falls.
