Biting The Baby

Most definitely herding behavior! Hopefully someone else will be able to give you advice on managing it.

Luvntzus is right, buy at least you know its not a aggression issue and you are knoweldgable about the breed. This has been discussed many times before so someone will be along shortly to help out. In the meantine we have a search section, you might try typing in keywords to see if something comes up. Maybe try
nip, nipping, heels, hearding, stuff like that!

Definitely herding...I've no idea how to change behavior that's instinctual.

I really don't think you will ever gid rid of her 'zest' to herd or chase, only controll it...
      By teaching her, whats right and wrong, i know how you feel to an exstent, because my sheepdog run's and tries to bite your ankels as you move, and if my kids are running,,,  'Watch out'
    But she is still young, and it needs nipping in the bud
 
    What i have done, is stuck to no!  means No!   and backed it up with the shake bottle...
   Hope this helps in some way...

Personally I would leash the dog to me while I was around the baby.  So that you can correct her as soon as the behaviour starts.  Never ever leave them alone.  Praise her heavily when she does something that you approve of like laying down and relaxing by the baby, or letting the baby pet her.  

Please note that I could be totally off on this as I have never had to deal with this behaviour before.  It's just the way I would correct any behaviour problems that involved immediate action.

the other reason you need to get it under control is for other children playing at your house.  There are two basic approaches  train alternate behaviors and management.  Basic obedience commnads (come and stay) are a must.  Train all day every day (practice sits, downs, come, stay) for a minute or two.  While doing dishes, watching TV, dusting, brushing your teeth, changing the kid, etc.  Management means restricting the dog's access to children in motion,  designated areas, leash to you, alternate location for the dog.

thanks! I will definately have her on a leash when shes around the baby, I was doing this while housebreaking but i guess its back on the leash for her!

Teach her "leave it" (check the archives - I wrote a protocol for it a while ago) and don't allow the kids to run while she is present.  Jumping on them is unacceptable and so is mouthing - she is treating them as equals.  The cure for jumping up is "sit", and the cure for mouthing is withdrawal of attention.  No eye contact - nothing - just quietly escape to the bathroom for 2 minutes.
If I can call a working Aussie off, and others can call a Border Collie off what they are focused on, I know you can learn to do it, too.  []

Two Words: Shock Collar

I'm a little disturbed that nobody's a little more concerned about your baby. You don't even seem that concerned. Teach the dog to "leave it"? Really? That means the dog will have to bite your child a few times. What if it gets riled up and puts one of those sharp puppy teeth into your child's eye? Or throat?

You think that social services will just let it go when your child has a gaping wound if you just explain that you were teaching the dog to "leave it" and that it would understand soon?

Two more words: Hell no.

Put a shock collar on that dog. Next time it's mouth opens NEAR the child, zap it good. If it's a stupid dog, it'll take two or three times before it starts to think "damn, this sucks, maybe I won't put my teeth on that thing".

Your baby should be your first priority. If you can't find a REALLY fast way to teach your dog not to bite your child, even if it's just nipping, the dog should immediately go or you should be put in prison and have your child taken away.

Harsh, but that's your child. Period.

Get a shock collar now. It'll help immediately and it only startles the dog. It's only a three volt battery. Seems like more though.

ABSOLUTELY DO NOT USE A SHOCK COLLAR TO STOP THIS PROBLEM!
 
If you want to use a shock collar that is fine, but train the dog on it properly.  The process takes about 24 days, and then you can use it to stop the nipping.  In the mean time keep the baby and the dog seperate. 
 
If you just strap on the collar, and shock the dog when he tries to nip your kid you have absolutely no idea what reaction you will get. I have seen some dogs lash out, some run away, some don't even react.  The above posters advice is lazy and dangerous.
 
I have no issue with shock collar (several of my dogs are trained on them), but this is NOT how you use one. 
 

I once had a dog that would nip visitors in the behind (never broke the skin but would leave a nice bruise).  I put a basket muzzle on her whenever we had company. 

That cute thing your dog does when she puts her paws up on your babies back when he's crawling around sounds more like a dominace thing to me.  Your dog needs to know that it is below your baby in rank and everyone else in the house for that matter. 

Having the dog tethered to you at all times around the baby is probably a good idea or at least have her on a drag line.  A prong collar might be something to think about as well to administer the proper level of correction.   If that doesn't work go with the shock collar like someone posted above. 

This behavior should not be tolerated at all.  Make sure you get the proper training/info to use these types of collars before you  try them of course.

gee, a shock collar/prong collar both sound like over-kill to me. This is a herding breed puppy. They chase things and nip them. All puppies regardless of breed are mouthy. Yes, all puppies do need to be taught to not mouth humans, but that is best done by withdrawl of attention.
Actually, what I find most shocking about this scenario is that the dog and baby are being allowed to interact. I don't think dogs should be allowed to interact with young children, and definitely not with babies. It's too dangerous.

Thanks Mic, for that reply.  I hate to see people use these things when they have NO IDEA what they're doing.  Like you said, there's no way to gauge the immediate reaction of the dog.
