i have a question for u guys. my chi does the weirdest behavior. at night when he winds down he becomes very very crabby. he starts to growl if u touch him while hes laying down and while he grows he starts kissing u. never snipps at us but has a very aggressive behavior. cant help but laugh at him cause he sounds like a little car engine trying to rev up while hes licking your face. i dont get it. hes also very protective too when company comes over. i know we spoiled him to much in early stages. hes a male,6 pounder, thats a little over a year old. he sleeps with us in bed too. cause were big push overs and didnt like him whinning by the bed and felt bad. plus we love to cuddle with him. what can we do except yell at him to stop when he does this growling kiss thing? what caused this to happen?
