#1)If you want to buy a dog that is not ill tempered than you should try this when it's a puppy. Of course make sure the dog is some what playful but also intelligent. Hold it in your arms, if it starts to squirm or wiggle and try to get away would mean it may be a hyper dog when it grows older. If it cuddles up and seems to be more relaxed it probably will be a lot calmer in it's dog years to come.
#2)Allergic to dog fur? Get a Shitzu. They actually have hair instead of fur.
#3)Chihuahuas are born with a soft spot in their skull. Which is very similar to human children. Human infants also close that gap in their skulls with age.
#4)Simply hold their arms and gently step on your dogs hind paws when they try to jump on you. This will cause them to feel a slight discomfort by making them realize it's also uncomfortable for you as well.
#5)Watch out for leaving antifreeze lying about for vehicles that are not animal safe. Usually Lethal... It fools animals because it smells and it taste good to them.
#6)If in case a dog attacks the first reaction might be to stick your arm out? Which actually could be the correct reaction. The reason it could be correct is because, instead of they're natural instincts, which is to attack your neck, they instead get a hold of your arm. Better to protect your self than to be harmed.
