Well i just got back in town from a week long trip (Sunny came with) and i noticed a real change in personality from him. I dont know if its just him growing up and not being so much of a puppy anymore or what but its so weird. He is 8 months old and got neutered kinda recently. Anyways so he has never been a real lap dog, if i get a hold of him he would sit still for maybe a few min but lately he at just been jumping up on my lap and sitting there for like an hour (not nessesarly bad but a huge change) in general he is just a lot calmer, letting me put in hair up in differnt ways and clip his nails and stuff like that. But then he also has gotten really protective of me, like if he is alone or if its just him and my mom and someone comes up to him he will just sit there but if i am holding him or if he is near me and someone comes near my he flips out barking and growling (not bitting but growling) and if another dog comes up to me and is sniffing me (we saw there 2 tiny maltese on our trip they must have been less than 3lbs full grown) he really freaks when the little malt jumped up on my leg while i was holding him he made sounds i have never heard from him....its not like he is bad around other dogs either i take him over my a friend of mines house whole has a lab mix he plays with just fine all the time. I guess what i am asking here is if this is normal for him to change? or is it even premenent?
