My 4 Month Old Papillon Is Being Aggressive At My Dad And Just Tried To Bite Him. Help?

My 4 month old male papillon loves everyone and covers them with kisses. Except my dad. My dad loves animals and it bothers him that the puppy hates him. He tried giving him treats and toys but it hasn’t helped. It started with just barking and growling while hiding behind me, but now he tried to bite him. I have been strict and tell him no over and over when he barks and growls but it has not worked. Help please!!! how should I handle this and train my puppy so he is not aggressive?

I Am 14. I Have A 1 Yr. Old Papillon. My Parents Say I Have 2 Months To Housetrain Him. Help.!?

He also, like most Papillons, does not like kids, and I have an 11 year old brother and a 2 1/2 year old brother. All during the day Louis ( my papillon) will play with the kids, but when he lays down on me and is napping, if my brothers touch him he growls and nips. But they aren’t just touching him, they are pulling on his ears and his tail. I mean I would bite too if I was rudely awakened. But my mother says that needs to be fixed too. I really want to keep my Papillon. Please help me with tips on house training him, and stopping his nipping. thank you.!
