Looking for a new puppy and need help!!!!

[DD977GM2]

Well my wife gave birth to a healthy baby girl on the 4th and I have had the pleasure of being home this entire time and doing what I can for the family and help the kids adjust as the 16 month old is not the center of attention anymore and my 6 year old is now truely the middle child.

So I asked him (6 year old) if he wanted another dog, we have a Staffordshire Terrier that is also 6 years old, and he said yes he wanted another dog. I also have finally convinced my wife to let me get another dog and that way we have 2 and my vicious baby killer mailman eater has a buddy.

So I come on here to ask folks if they know anyone or have puppies of any of the breeds listed below and I'm not really interested in any other kind of breed. I am looking for a puppy only and no older then 6 months since i have kids and want to train them right from the start. Preferable being a male as for some reason all the females I have had are fence jumpers and escape artists.

1. Rhodesian Ridgeback

2. Belgian Shepherd Malinois

3. German Shepherd (GSD & Husky mix is acceptable)

4. Cane Corso (price will prob prevent this)

My price range is honestly no more than $500 and AKC is not a must.
I am Interested in them having good hips and generally parents having good health.
For the record I have a big backyard and my dogs are part of the family and sleep inside and usually with one of the kids and go everywhere with me when the car isn't loaded with everyone. Also my pitbull is well socialized and good around other dogs.

I appreciate the insight to anyone who knows breeders or owners looking to rehome etc.
