When should I start training my puppy?

Training your puppy should start as soon as he or she is weaned.  Prior to this the puppy is learning about life from its mother and the rest of the litter.  

What can I start teaching my puppy?

Things that can begin right away: Housebreaking, learning to walk nicely on a leash, no jumping/biting, how to socialize with other dogs and humans, etc.

I can't seem to teach my dog anything!  When should I contact a dog trainer?

It is time to hire a trainer when you sense that your dog has mild/moderate issues, and the methods you have been using are not working.  It is best not to wait until things get REALLY bad.  It is easier on the dog (and you!) to get the problem solved before it gets out of hand.  Very often small problems can escalate into big ones, very quickly. 

What are some warning signs of bad dog behavior?

Examples of things that should be handled right away:  Your dog lunges at other dogs/people when out.  Your dog jumps on everyone, and is always very excitable.  Your dog has no manners.  You have more than one dog in the home and they are growling or fighting with each other.  Your dog growls at you when you go near him if he has a toy or something of value.
