Puppies are puppies, they are usually high strung, energetic, and all over the place. Bully breeds NEED a strong, even tempered handler that understands the breed. These dogs have a strong urge to be in the alpha position. A lot people think these dogs need punishment and smacking to train them, this is not the case with any dog, let alone a powerful dog like a pit. Remember they key in a good dog is not having them fear you, but respect you. You want to make sure you are the alpha of the pack.
Most alpha's in the wild are actually even tempered. When you yell, it makes your dog panic, thinking you don't know what to do and are "barking like mad". Your dog will step in and try to gain control. Using simple commands like "sit", "down", "stay" and "leave it" are among the most important to have mastered. Like mentioned obedience will be your BEST FRIEND with this breed. Yes it's expensive, but it's so WORTH it to have a well adjusted dog in your home.
Dogs by nature are protectors. If you are looking for a guard dog in the sense that your dog will bark and bare teeth to un wanted strangers, most will. Beside most "burglars" only need to see a big dog, and they will think twice about entering a home. Unless you have a license for an actual guard dog, and the papers to back it up, a biting dog usually ends in a law suite.
Now I will touch on the spaying of your pet.
PLEASE, PLEASE, PLEASE get your girl spayed.
Here are some statistics to think about.
Approximately 5 million to 7 million companion animals enter animal shelters nationwide every year, and approximately 3 million to 4 million are euthanized (60 percent of dogs and 70 percent of cats). Shelter intakes are about evenly divided between those animals relinquished by owners and those picked up by animal control. These are national estimates; the percentage of euthanasia may vary from state to state.
Only 10 percent of the animals received by shelters have been spayed or neutered.
Five out of ten dogs in shelters and seven out of ten cats in shelters are destroyed simply because there is no one to adopt them.
And here are some facts on spaying and neutering your dog.
Spaying removes the risk of pregnancy.
Spaying makes for a cleaner, calmer dog.
Spaying keeps your dog healthier.
Spayed pets tend to have fewer health problems. Spaying is the removal of the ovaries and uterus. Without these organs, ovarian cysts, uterine infections and cancer of the reproductive tract are no longer a concern. Studies have shown that dogs spayed before puberty have a significantly lower chance of developing breast cancer than unspayed dogs or dogs spayed later in life.
Spaying keeps animal shelter populations LOW.
