I'm not sure what your wanting to know exactly. Are you asking if it is normal to tie that many times? They will tie as many times as allowed and/or until the bitch turns him away. You can bet she is pregnant. When did this all happen? How much does each dog weigh?

Your brother needs to know that it is irresponsible and potentially dangerous to let them breed. If he tends to continue with the pregnancy I suggest he starts studying up on what he needs to do to prepare his girl. A lot can happen & a lot can go wrong. He needs to be responsible with the pregnancy and whelping now.
