Who has a mixed breed dog/s (american bulldog & staffordshire terror)??

I have a dog whose mom was German Shephard and the dad was a black lab. The owner was mad because the shephard was full breed and he bred pure breed puppes with her? But his black lab male jumped the fence when she wss in heat and he missed a breeding season. LOL! (Gotta check that fence?) Everyone told us shephards could be mean and just because she looked like her dad, it didn't mean she would not act like a big shephard and be bad around kids? But ..it is in the way you raise them! You should treat your dog /puppy like a little baby and get toys, etc..and it'll be just fine! Talk in a high happy voice when it acts well and give praise..ignorethe dog when it makes a mistake. It wants to please you. Take the lead. Dogs are pack animals..you have to be the pack leader! (Or IT will take that position.)Tickle the puppy, talk to them like a baby and nap with them. It'll be OK. A dog has to be trained in how to behave, train a dog to be mean and it will be. But train them to be like a baby..they will be great with little kids! We took our lab/shephard puppy for free..and she has been beautiful. Looks fully like her dad..like a black lab! And she is such a baby..a little afraid of thunder and lightening and 100 pounds/6 years old now..but we love her to bits!
