My dads gf just bought a new puppy a few weeks ago. I know my dog smokey has to get used to it, but he keeps attacking her every time she walk near me or i play with her. I give him way more attention that i did befor she got here. I spend alot of one on one time to let him know hes still #1, but everytime i play he either gets really angry or really sad. I have tried to play with them both as the same time and I always greet him 1st when I come home. I dont want him to hurt her and we do have a crate for her for when we are gone. Im not sure what else to do and now he wont eat food unless i sit next to him while he eats and pet him or he will want me to feed it to him.
