Has he always been aggressive or just since the baby came ? If this is new then he is claiming the baby & feels he needs to protect her from your daughter & husband & this is not uncommon & could also explain the potty issue. If he's feeling protective then he will feel the need to mark territory to let others in HIS pack (husband & daughter) know that this is HIS territory & HIS new puppy (your baby ). It sounds like he doesn't know where he stands in the pack anymore & you need to reestablish who is ALPHA in the house. |
