I don't mind roaches as much. If I see a roach running around my kitchen, I see it for a second then look away..nothing special. If I see a tarantula running around my kitchen, my blood pressure will definitely go up. Then I'll try to catch it and put it in a mayonaise jar and feed it a roach.
Nah..I'd release the tarantula, and I'd try and squash the roach...if I'm not too lazy to get up and do it.
Sombra..what do you want to train your dog to do? Do you want a circus dog?? Just play with him. Oh, wait...I guess you should train him not to bring down your laundry when hung out to dry. Or dig too many holes or get out of your backyard... Hmm.. I think you can just smack him on the nose when he does something wrong (AT THAT VERY MOMENT ONLY) and scold him with an authorative tone..but don't hit him so hard that you make him whimper...that breaks my heart.
