shaking and weeing

hi all
my staffie blake is now 1yr and 4months and i have a bit of trouble with him now and then.
when blake is bad and has done something wrong
i.e : nipped the slipper

i will say blake no and tell him bed but some times he starts shaking and will wee but it seems like a uncontrolled wee if that makes sense.

i have had him from birth with his mother but any other time he is ok. it also doesn't seem to be all the time i tell him off.

Sounds like the weeing maybe a nervous reaction to being told off. When was he last checked over by the vet, as it could be an infection.

Maybe try swapping the stolen slipper for something he is allowed to have and avoid the telling off bit.

Maybe sometimes you're more stern than others?

As Kathy says, try to swap the forbidden item with something he's allowed.
