We have a 16 week old F2 who is absolutely wonderful until you try to sleep with him at night. During the day there is no biting or attacking if he is in the human bed but at night when you settle in for bed his behavior completely changes and he ends up having to sleep alone or should I say us the humans have to. I want him to be able to sleep with us but his demeanor completely changes and he get very rowdy and BITES and pounces. Any suggestions?! If you are anywhere else in the house with him at night his behavior does not turn to this. It is in the bed only.
