I’ll get some more picks of my little monster posted here shortly.. I recently transferred all pics from my laptop to an SD card for storage (replaced the laptop).

Also wanted to mention — with ivermectin/heartgard, dosing should start one month AFTER heartworm season begins. Since heartgard doesn’t build up in the system and kills L3 and L4 stages, if there has been no bite there can be no L3/L4 to kill. And it would have been impossible for the L1 stage larvae to show up on the test if you had been using. That could have made knowing the stage/class harder??
