My now 4 month old pup Milo, have progresses from play bites/nipping to ripping sleeves, pants and almost drew blood. I must have done something wrong?? I tried the "ouch" and time-out technique, but that didn't seems to deter him.
His bad behaviour almost always started in the afternoon and during the time I take him out to the backyard (to relieve himself). For the past week, after he was done, he would take one look at me and jump for my pants and chomp as hard as he could. Any attempt to stop him (either by keeping still, holding him down or redirecting him) was rewarded by bite marks and torn sleeves.
By then I would run back to the house (with him chasing and trying to bite me) and closes the screen door. Normally it would take 3 tries and time-out to cool him down. Then when I allow him to enter the house, he would return to his sweet self. It's frustrating... any advise would be greatly appreciated.
Btw, is there any correlation to his somewhat aggressive play with other pups and his over excited reaction towards strangers? with this burst of violent behaviour?
