if you want
You can buy a pre-trained dog, or if your looking for a puppy you can hire a trainer. I recommend local breeders.
Dog should always be trained because without training they will ruin your house and furniture, and they will be very mean and they will think they are the person or dog in charge, and they should not be the one in-charge, you should be.
It is not normal or appropriate for a dog to lick a girl's buttocks. This behavior should be discouraged and the dog should be trained to respect personal boundaries.
You should train him first, then feed him. It makes him work for the food.

Any dog should be compatible with a Collie if both are well-trained, de-sexed, and have nothing to fight about. There's no reason why they should not get along.
any age but no fogies should buy them
I may not be perfect, but a good dog training system is one of positive reinforcement. This means whenever a dog does what you want it to, you give the dog treat and praise. When a dog does something bad, you simply say no in a stern voice.
Any wild dog that has not been socialized or trained should be considered dangerous. Even dogs that have been socialized and trained can be dangerous.
If a service dog is trained correctly, then it will be potty trained.
It doesn't matter too much, but you should buy from a breeder. If you end up adopting, the dog will love you the same..
I think you have to be a dog handler
