I figured I would elaborate on the post above me, and my previous one.
Puppies-
*Need CONSTANT supervision. In order to housetrain, they need to be taken out every couple of hrs, and be tethered to you when not crated. If you take them out, and they don't go to the bathroom, you need to wait 15-20 min and try again. There WILL be accidents. You need to clean those with an enzyme cleaner. Will your 2 yr old find the poop before you do? They chew on anything they can get their teeth on. Baby's toys and pacifiers are fair game. If the puppy swallows it, then you may need to make a late night ER visit to vet. Do you have child care at all hrs so you can get to vet? Funds for ER vet?
*Puppies can be noisy and bark and cry- waking the baby you finally got to sleep.
* Puppies need to be socialized and trained- Can you have other friendly dogs over that are also good with kids, so you can do the needed socialization? Can you attend puppy training classes?
* Puppies have VERY sharp teeth, and bite- Your 2 yr old may not like being used as a chew toy. Do you know how to train bite inhibition? Will the biting puppy scare your toddler and baby and make them dislike dogs? You do not smack dogs to discipline them, and if you do that to a dog like an Akita, you can make them mean and distrustful
* Akitas are high energy- Do you have the time to do an hr walk/jog in am and another in pm? Without proper exercise, Akitas will be destructive. They can escape yards without high fencing, dig proof fencing.
* Akitas grow a fluffy undercoat and require daily grooming. Even doing so, they blow their coat twice a yr and shed yearround. Are you ok with having fur everywhere, with babies crawling around? Do you have time to vaccuum daily?
*You cannot just leave your dog outside. It needs to be socialized. Left on their own, they will be destructive, jump on people, bite, and may become aggressive or bite people coming into the yard. They will also bark and howl nonstop, bothering you and neighbors.
Read some of the stickies at the top of the first time owner and training forums. Notice how many threads people have about "I'm at my wits end with puppy" "Help! Destructive puppy" "Help! Puppy Bites" Help. Puppy won't stop peeing in house".
Puppies are cute, but not great for first time owners and definitely not for a first time owner with a 2 yr old and another on the way. Then add in that it is a "harder" breed like an Akita, and it really isn't a good idea. Please reconsider. Not only for your own sanity, but also for the puppy's benefit. Too many people jump into getting a cute puppy, and then when they find out how hard it is, throw the dog out back, or get rid of it. Please don't put another living creature's life/happiness/wellbeing at risk, because of some idyllic dream of your child growing up with a puppy. It doesn't normally work out. If your heatr is set on a dog, wait until after the new baby is born, and is sleeping thru the night and get an adult dog that has proven to love kids. I promise you, you will be much happier.
