Stealthing around your pet does not actually work.
Someone said a while back that you have to make the pet attack you then stealth.
Other way is go to trap spiders in abandoned city, outside the night terror area. (Stay away from them, lol). The trap door spiders also LP go get ready for them, make sure you have protection, petals etc on.
In terms o f utility DH on pets may be an exercise in futility, probably will take quite long also, but something to do I reckon..
