WE have had our dog1 for 12 years, since he was a pup. He has always hated the postie since one tormented him through the door years ago. He has bitten them on 2 occasions (with 2 near-misses), and regularly eats the mail.
In the 6 months since ds has been born, the following things have happened:
He destroyed his change-mat, which was left on the floor while we were out, probably when the postman came. (He does attack items near the door if he can't eat the post, but this wasnt near the door).
Since then he has been muzzled when I am on my own with him and ds.
Then, dh was in the garden when the postie came and dog1 was loose. Dog1 attacked postie, but dh got to him first and dog1 bit him (not hard, and also immediately realised his mistake).
Then today, I came back from visiting friends, and dog1 was unmuzzled when we were out. Dog2 got excited, as always, and tore around the house, with his bone. Dog1 attacked Dog2 and I had to literally kick him off twice. This is while I was carrying ds.
Dog1 has grown up round other people's children, and has never bitten them even under duress. He has never shown any aggressive tendencies towards ds. He is also extremely obedient in every way, except when it comes to the postie.
Dad has offered to take him, but he doesnt really want him. He has had dogs all of his life, and his died recently. Dh wants to keep him, but have him muzzled whenever ds is awake. This dog is an old family pet, and we love him dearly, but obv ds's safety comes first.
What do we do?!?!
