Thank you so much for your answers, The only other weird behavior speedy has is if my mother comes to visit me, speedy automatically clings to her and he turns on me he growls and tries to attack like if i was a stranger and its even worse if i bring him to visit at her house. Is that an OCD behavior or just an aggression problem? Speedy does tend to hump the stuffed animal and he is not neutered. The only change he has gone through is just that i switched that junk biproduct food to a healthy organic food.
So other chihuahus do this? But not as extreme as mine? lol it was starting to really worry me.
The stuffed animal is not made for specifically for dogs, but he even did this since he was a puppy and at times he becomes very defensive with the toy like lets say i get near him and he is laying down and i walk next to his stuffed animal he will jump out of bed and stand in front of the toy and growl at me and even try to attack. Is that normal? I dont know what to do his aggression is getting pretty bad and nothing seems to help.
Yesterday i took the stuffed animal away and he cried for s little while and just roamed around the house searching for it, but now he is getting out of bed a little bit more but not much he just wants to sleep now like if he is sad or something.
Thank you so much for your guys help!!
