Dog Training  

that depends, if you want that your dog to pup every were, then you don't need to train them.

Of cause is it necessary if you want to make sure nothing bad like your dog attacks innocent people happens .
Training a dog is kind of like a safety precaution so that they wont turns to be violent easily .
But , of cause we can keep our dog without training because it is though optional right ? Not many people can afford those pay for the trainings .

Of course you have to train your dog. It needs to know what you expect from him. Dogs are like keeds and need guidelines and since they have a p[ack mentality it is best if they know you are boss. Which they pick up through training.

Sure if you don't mind him peeing and pooping all over your house and jumping on everyone and barking all the time...but why wouldn't you want to train your dog?

I believe dog training is critical when owning a dog. They are like children that need to learn rules and boundaries. They want to please their owners, but need to be taught how. Good training early, makes for a great dog for life.

I'm not sure why you would want an untrained dog? Training a dog keeps them from jumping on others, keeps them from helping themselves to your food, keeps them from running crazy and doing what they want and keeps them from going to the bathroom anywhere they want in your house. If you mean "training" in the sense of "sit", "stay", "speak", etc. then that's not really a huge deal that they know how to do what most consider tricks. But I think any animal that is kept as a pet should be trained to some degree.

i dont think dog training is very necessary if you have basic skills of dealing with a dog.. and if you just wanna have a dog is absolutely not necessary.. but if you want special features like jumping etc, or sniffing etc... you ought to go for a training
