I think your oldest is just establishing himself as the 'alpha' from day 1. While I would not allow biting, try not to intervene too much if you can help it - provided no one is actually getting hurt.
My Westie would stand over top of Lucy (yorkie) and growl . . and it was very scary. She would yelp like she was dying - but he never, ever bit her. He was just showing her that he was boss.
That settled down quickly but only AFTER we quit correcting him (unless he went overboard) AND we tried to pay more attention to our oldest than our new puppy. This let him know that he was still 'top dog' and had not lost his status in our home. This helped him with jealousy and they get along fine now. We are still careful about feeding them separately though.
It took about 3 weeks; and YES, I too wondered if I should return the pup for her sake! Now, I don't know what they would do without each other.
So, don't feel guilty! Keep your patience and keep us posted. |
