So I got into a little discussion with my DH tonight about his brother's dog and how I wouldn't feel safe having him around our baby/toddler/child because he's shown significant aggression towards other dogs, including our submissive sweetheart of a chocolate lab. In fact, in order for them to be near each other, brother-in-law's dog has to be muzzled which was decided and enforced by BIL, not us! This dog is a very sweet and well behaved dog around BIL, his GF, and most humans to be honest... However, I've never seen him around a baby and I don't want MY baby to be the 'test drive'.
BIL's dog is one of those breeds that has a reputation to have the potential 'mean streak' and while I don't subscribe to the 'all dobermans, pit bulls, chows, etc." are vicious, I am admittedly cautious around all dogs, especially certain breeds. BIL's dog was adopted at a young age (but not puppy) and must not have been properly socialized... I'm just unsettled because we don't know his history prior to adoption and I've seen his grouchiness first hand--it's intense, violent, and to me it seems like without that muzzle he'd bite to kill.
SO... my argument is, it only takes once. One bite to scar an innocent baby face, one maul to disfigure for life, one (G-d forbid) violent attack to take the life of a small person... Am I crazy to insist to DH that BIL's dog must have his muzzle on and preferably be in the yard when we're at their house or the in-law's? DH thinks he's a sweetie... and I'm inclined to agree that sometimes he is... but still, doesn't it only take once? DH respects my opinion and will respect my wishes and concerns... this wasn't a heated discussion or argument, but more of a debate and clearly, while he's capable of respecting my thoughts on the issue, he disagrees

Paranoid? Reasonably cautious? What say you ladies?!
Re: What Would You Do? Aggressive Dog...
That said, you need to feel comfortable with the dog. I think the dog should wear the muzzle if/until he proves he can be around the baby. If he even once shows aggression, then I would absolutely ask to keep him separated.
If it means anything, my BIL's pitty was very scared and overly anxious around little ones (he was abused by children) and we were all terrified about bringing their baby home. They slowly introduced him to baby, supervised any contact etc, and now the dog is obsessed with my nephew. Loves him! And he is also very aggressive with some dogs. I say give him a chance, but be overly cautious.
I've been attacked by a large breed dog. An infant would not survive that. Don't take chances with your child's safety just to spare someone's feelings.
Edit: Also, I grew up with German Sherpards and love big dogs but we did have one that had a previous owner and was always a little skiddish around people outside our family / other dogs. She ended up biting one of my sister's friends even though she was trained.
Maybe you could use a specific blanket with LO for a few days then give it to BIL to let his dog get used to the scent?

I have two dogs a jack Russell and a golden retriever. Even though my two are great I would never leave them slob with the baby. You never know what might make them turn and bite.
I am happy to see that BiL is aware but even with a muzzle on I would not want my baby around that dog.
I would want the dog in another room or outside if they would not. I would not bring baby to the house.
Just my opinion.
I'm not new. I just hate The Bump.
If it was my dog acting a fool I would have more patience with trying to work it out, but even then only to an extent. I shared a story earlier this week about a kid in Lincoln's music class who basically got his face mauled by the family pet. Since this dog doesn't even belong to you, I would absolutely draw the line and not give a crap what anyone thought. If they don't like it they can come to your house for visits so the dog is a non-issue. This will be your BIL's niece. She takes precedence over any dog.
& @shiggybop, I did explicitly say that "I'm admittedly cautious around all dogs" in my original post.
Unfortunately I too have stories which I didn't previously share here... But the worst involves a dear friend's sweet dog of numerous years who snapped and all but killed his cat pal whom he'd grown up with from a puppy--no warning. My friends had a new baby at the time and made the difficult decision to re-home their beloved dog of 6 or so years... Thousands of $$ later, kitty is fine... Moral is, I do agree with many PPs, exercising caution w/ all pets and animals is very very important.
Ok, technically it's a cat vs dog fight but that cat has light sabers!!!!
