Ok so we just got jasper last week and everythings going good BUT I also agreed to dog sit one of my friends yorkies ( tiny) and he's mean! He's bitten all of my kids not their fault and pees and poops everywhere I mean jasper is 12 weeks and has less accidents then tiny. Tiny is almost 2 yrs old I feel so bad for this dog I don't know if this means they don't pay attention to him or what? Hes a cool little dog besides that I'm just baffled at how mean he is
