My puppy just turned 6 months and about 3 days ago something "new" started... He usually always goes right to bed when I put him in his cage (around 9 or 10 o'clock) but for the past three days or so, someone might walk by my room and he'll start to growl and bark, is this normal? Is he just getting protective? He seems to do it even at like 2 or 3 in the morning and it scares the sh*t out of me. Then he looks at me like "oops sorry", is this something to get use to?
Any input is greatlyyy appreciated.
