My yorkie Jack gets randomly insane when we are playing with toys or sometimes just sitting in the house and especially if i tell him no when he bites me. he'll start barking and barking and barking... he's to fast to catch- i've been told to hold his mouth shut. i've started walking away from him and he'll stop and follow me, but it isn't enough to calm him all the way down. in a couple minutes he'll start again. i've recently started time-outs in his pen with no toys, but he still persists. he never does any of this to my husband, or guests, just mama. any suggestions?
