Dog's personality

Dogs can come in different sizes, shape and behaviour.

Have you seen some dogs who can get along with cats and some who will bark at cats?
This occurs because they have a different personality and background.

I classify them into 2 groups: Tame and Aggressive

Tame characteristics: They are very calm, always smiling, wagging their tail often and friendly to you. The ideal pet for most dog owners.

Aggressive characteristics: They bark with a high-pitch tone when they sense movement like when a cat is around, they sniff a lot when they walk, most of the time they pull the leash real hard when untrained.

These are the 2 most common groups I notice from my observation. Tame dogs are ideal pets whereas aggressive ones are more like a hunting dogs but can be still kept as ideal pets if trained properly. Take advantage of your dogs aggressive characteristics as he can be a good guard dog when you are away or asleep. Tame dogs are less likely to bark at people, for example, everytime I go to my cousin's house, his Golden Retriever would not even bark at us (definitely tame) whereas his other dog would bark at us (definitely aggressive.) His Golden Retriever jumps on us when we come near her as a sign of saying "hello" and his other dog (aggressive) once bitten my aunt when she wanted to feed him when my cousins were away from home.
